Litime Batteries - WattBuild

**This report provides an in-depth analysis of LiTime (formerly Ampere Time) Lithium Iron Phosphate (LiFePO4) batteries for the consumer do-it-yourself (DIY) solar and battery backup market. The central finding is that LiTime products represent a significant "Value-Risk" dichotomy. The brand's primary value proposition is its highly aggressive price-per-amp-hour, with extensive independent testing confirming that its batteries consistently meet or exceed advertised energy capacity specifications.[1]
This value is counter-balanced by a high-stakes gamble on long-term reliability and, most critically, post-sale support. The research identifies two major risk vectors for consumers:

Manufacturing and Design Inconsistencies: Despite heavy marketing of "Grade-A" cells[3] and advanced, automated manufacturing processes[3], there are documented consumer reports of severe quality control (QC) failures, including units arriving with liquid sloshing inside.[5] Furthermore, independent safety testing has revealed latent failures in the Battery Management System (BMS), including one instance where the BMS "smoked" during a standard short-circuit test.[6] Additional analysis of community reports reveals non-obvious BMS logic flaws that are detrimental to common DIY applications, such as parallel-connected battery banks.[7]
Adversarial Warranty Support: The most significant risk identified is the LiTime customer support and warranty process. The 5-year warranty[8] is a cornerstone of the brand's marketing. However, multiple detailed consumer reports allege a pattern of denial, user-blaming, and "run-around" tactics when valid warranty claims are filed for failed products.[5] This extensive anecdotal evidence is externally corroborated by an "F" rating from the Better Business Bureau (BBB), issued for the company's "Failure to respond to... complaint(s)".[11]

This report concludes that the 5-year warranty functions more as a marketing asset than as a reliable consumer protection. A LiTime battery is a suitable purchase only for a technically proficient DIYer who is capable of diagnosing and repairing the unit (e.g., replacing a failed BMS)[12] and who treats the purchase price as a sunk cost, effectively "self-insuring" the product.

I. Manufacturer Profile: Shenzhen LiTime Technology Co., Ltd.

Corporate and Operational Structure

The manufacturer of LiTime batteries is Shenzhen LiTime Technology Co., Ltd., a company based in China with facilities in Longgang.[3] The company claims over 14 years of experience in lithium battery production and renewable energy solutions.[3]
LiTime operates a direct-to-customer (D2C) model, minimizing costs by selling directly through global online storefronts[13] and cutting out traditional distributors.[4] This model allows for aggressive pricing. In addition to its consumer-facing brand, the company also operates LiTime Solutions, a dedicated B2B division for industrial and customized solutions.[16] The company's product scope extends beyond batteries to include a full energy ecosystem, offering solar panels, inverters, and solar charge controllers.[15]

Manufacturing and Quality Claims

LiTime's marketing heavily promotes its manufacturing sophistication. The company claims to utilize automated assembly lines, AI-powered defect detection, and a 12-point inspection system to ensure quality.[3] It also states that its batteries are built using "EV Grade-A LiFePO4 Cells"[4] and adhere to a range of international standards, including ISO-certified protocols and certifications for UL 1642, CE, RoHS, and UN38.3.[3] The company further claims its products are "Tested Beyond Industry Standards" in an in-house lab that simulates harsh conditions.[4]
A central theme of this analysis, however, is the significant gap between these sophisticated claims and the reality of consumer-reported quality control. Reports of batteries arriving with liquid "sloshing" inside[5] and, in a formal teardown, a BMS "smoking" during a standard short-circuit test[6] directly contradict these assertions of high-level quality assurance.

Analysis: The Strategic Rebranding from Ampere Time to LiTime

In late 2022, the company fully rebranded from its previous name, "Ampere Time," to "LiTime".[3] The official company narrative framed this as a natural "evolution" and an opportunity to "better represent who we are"[21] and "innovate the new energy industry".[22]
However, forum discussions from the transition period reveal significant market confusion and provide a more nuanced explanation.[23] Consumers noted identical case markings, identical website "Our Story" pages, and even the same eBay seller ('amperetime_us') shipping both brands. One user astutely observed that the Ampere Time brand (the older one) retained the "higher capacity options" and "self heated options," while the new LiTime brand was being introduced at a lower price point.
This evidence suggests the rebrand was not a simple rename but a "brand flanking" strategy, similar to an "Acura/Honda or Lexus/Toyota" model[23], to segment the market into "high end" and "low end" tiers. The company eventually consolidated its entire portfolio under the LiTime banner.[24] For the DIY consumer, this history is critical: all technical reviews, forum complaints, and failure analyses for "Ampere Time" are 100% applicable to "LiTime," vastly expanding the body of available consumer data for assessing the product's long-term performance.

II. Product Portfolio Analysis for DIY Solar Applications

LiFePO4 Voltage Tiers (12V, 24V, 48V)

LiTime offers a comprehensive range of voltage-tiered "drop-in" LiFePO4 batteries, making them highly relevant for all common DIY solar architectures. Their product lines include:

12V Batteries: The most common standard, for smaller RV, van, and marine systems.[25]
24V Batteries: Used in more efficient, higher-power RV or small off-grid cabin systems.[25]
48V Batteries: The standard for larger, residential-scale home battery backup and off-grid solar systems.[14]

The company also offers specialty voltage batteries (e.g., 16V and 36V) targeted at specific markets like trolling motors.[14]

Feature Segmentation: Decoding the "Good, Better, Best" Model

LiTime's product line is heavily segmented by features, which can be confusing to a new buyer. These features are additive and are primarily differentiated by the capabilities of the internal Battery Management System (BMS).[14]

"Classic" Series: This is the price-leader, entry-level model. It features a basic BMS with standard safety protections (e.g., over-charge, over-discharge) but offers no external monitoring or cold-weather mitigation.[14]
"Bluetooth" / "Smart" Series: The mid-range tier, which includes a Bluetooth 5.0 module. This allows the user to monitor the battery's State of Charge (SOC), individual cell voltage, and BMS status via the "LiTime" mobile app.[14]
"Low-Temp" (LT) Series: This feature is critically important and frequently misunderstood. This is Low-Temperature Charging Cut-Off Protection.[19] The BMS will prevent the battery from charging at temperatures below 0°C (32°F).[19] This is a crucial safety feature to prevent irreversible cell damage (lithium plating), but it does not enable charging in cold weather.
"Self-Heating" Series: This is the premium cold-weather tier. These batteries include both the low-temp charging cut-off and an internal heating mat. The BMS intelligently uses the incoming charging current to warm the cells to a safe temperature (e.g., above 5°C) and then allows the charging current to flow to the cells.[14]
Other Tiers: The company also offers "2C-Rate" models for high-discharge applications[14], "ComFlex" models with RS485 communication ports for data logging[14], and various case sizes (e.g., "Mini," Group 24, Group 27, Group 31, 8D) to fit specific vehicle and marine battery trays.[19]

The LiTime Ecosystem

LiTime aggressively markets a complete, vertically integrated ecosystem, encouraging users to purchase LiFePO4-specific AC-DC chargers, DC-DC chargers (for vehicle alternators), solar charge controllers, and pure sine wave inverters.[17]
While this strategy encourages users to stay within the LiTime brand, it does not guarantee seamless component communication or system stability. In one documented user report, a consumer who had purchased a full LiTime system (battery, DC-DC charger, and Inverter-Charger) still experienced critical system instability, with 12V loads flickering and voltage fluctuating.[30]

Table 1: LiTime Feature-Set Comparison (Common 12V 100Ah Models)

Model	BMS Rating	Bluetooth App	Low-Temp Protection	Self-Heating
12V 100Ah "Classic"	100A	No	None	No
12V 100Ah "Smart" (Bluetooth)	100A	Yes (LiTime App)	Cut-Off at 0°C	No
12V 100Ah "Self-Heating"	100A	Yes (LiTime App)	Cut-Off at 0°C	Yes

Note: This table represents common configurations. Specifications may vary. Data sourced from.[14]

III. Core Technology Analysis: Advertised Performance and Specifications

The LiTime Battery Management System (BMS)

The BMS is the "brain" of a LiFePO4 battery, responsible for safety and performance. LiTime claims its self-developed BMS provides "20+ protections and warnings".[19] Key advertised protections include:

Over-charge and Over-discharge protection
Over-current protection (with auto-recovery)[20]
Over-heat and Short-circuit protection
Low-temperature charging cut-off[4]

Despite these claims, there is evidence of confusing and contradictory specifications in LiTime's marketing materials. One forum user analyzing a 48V battery noted the product page listed a "200A BMS" but a "100A Max Discharge," while the corresponding Amazon listing for the same battery claimed "10.24 kW Continuous Power Output" (which would be ~213A at 48V).[31] This level of specification ambiguity is a significant red flag for DIY builders, who depend on accurate continuous and peak discharge ratings to safely size critical components like fuses, wiring, and circuit breakers.

Cell Quality and Advertised Cycle Life vs. Depth of Discharge (DoD)

LiTime advertises an extremely long lifespan for its "Grade-A" cells, with common claims of "4000+ cycles@100%DOD"[19] or, more broadly, "3000-6000+ cycles".[32]
This "4000 cycles at 100% DoD" claim is an aggressive marketing figure. While LiFePO4 chemistry can be safely discharged to 100% (unlike lead-acid batteries, which are typically limited to 50% DoD)[32], an inverse relationship between DoD and total cycle life is a fundamental principle of all battery chemistries. General industry data for LiFePO4 cells shows that while 100% DoD might yield ~3,000 cycles, a shallower 50% DoD can increase the lifespan to ~8,000 cycles or more.[33]
The most effective way for a DIYer to ensure longevity is to oversize the battery bank, thus ensuring a lower average DoD (e.g., 50% or less).[33] LiTime's "4000 @ 100%" spec, while technically impressive if true, is poor guidance for designing a long-lasting and durable system.

Charge/Discharge Ratings and Voltage Curves

The BMS rating typically dictates the continuous charge and discharge current. For example, a 100A BMS allows for 100A continuous discharge[19], and a 200A BMS allows for 200A continuous discharge.[20] For optimal battery life, LiTime recommends a much slower 0.2C charge rate (e.g., a 20A charge current for a 100Ah battery).[29]
LiTime provides voltage charts[35] that illustrate the characteristic flat discharge curve of LiFePO4. A 12V battery is 100% full at its charging voltage of 14.6V, rests near 13.4V, holds a "nominal" voltage of ~13.2V for the vast majority of its capacity, and is considered 0% when the BMS cuts off discharge at ~10.0V (based on a 2.5V per cell cut-off). This extremely flat curve makes monitoring the State of Charge (SOC) by voltage alone notoriously difficult, reinforcing the practical value of the "Smart" models that use Bluetooth and a coulomb-counting app.[19]

IV. Independent Validation: Expert Teardowns and Community Benchmarking

Synthesis of Expert Reviews (The "Prowse" Effect)

The DIY solar community heavily relies on technical reviewers, most notably Will Prowse, whose tear-downs and tests are considered a benchmark.[5] LiTime has actively targeted this network of influencers, providing free products for review and testing.[1]
A review by Prowse is referenced[40] as being largely positive, noting that LiTime's build quality is "getting better over time," the new BMS is an in-house design ("it says lie time on the BMS"), and the battery offers "fantastic for the money" features like low-temp charging protection. His review concludes, "I would buy this battery".[40] This sentiment has, in part, fueled the brand's popularity.

Comparative Teardown: LiTime vs. Premium Brands

A 2024 comparative teardown and stress test by Mortons on the Move provides a stark and critical counter-narrative.[6] This test put the LiTime battery head-to-head against premium competitors like Battle Born. The findings were damning:

Build: The LiTime battery was the cheapest in the test and exhibited "weaker build quality" and "lacks proper certifications" when compared to the Battle Born.
Cell Matching: The LiTime unit showed "significant voltage imbalance" among its internal prismatic cells, indicating poor or non-existent cell matching at the factory. Poor cell matching is a primary driver of premature capacity loss and battery failure.
BMS Safety: This was the most critical finding. The LiTime BMS failed overcurrent tests. During the short-circuit test—a test of the BMS's most important safety function—the LiTime BMS "smoked," indicating a catastrophic failure of the protection circuit.

This creates a serious dichotomy for the DIY user. While some reviews find the battery to be a great value[40], this more rigorous safety test suggests it is a risk.[6] The implication is that the battery may pass basic functional tests but could fail to protect the battery (and the user's property) in a real-world fault condition.

Community Capacity Test Results

On one point, all independent testers and community members are in universal agreement: LiTime batteries deliver on their advertised capacity.
Multiple independent YouTube reviews confirm this. One test of two 100Ah batteries found they "passed the discharge deep cycle. test" and both had "in excess of 100 amp of capacity in them".[1] Another review of a 100Ah "mini" battery noted that it "overdelivers on capacity".[2]
This is the core of LiTime's success and high sales volume.[41] Customers are verifiably not being cheated on amp-hours. The brand delivers the promised energy, which builds a strong baseline of trust and makes the value proposition compelling.[42] The gamble is not on capacity; it is on longevity and safety.

Table 2: Advertised vs. Independently Tested Performance

Specification	LiTime Marketing Claim	Independent Lab & User Test Results
Energy Capacity	100Ah	Pass: Meets or exceeds 100Ah.[1]
Quality Control	"12-point inspection"[3], "AI-powered defect detection"[3]	Fail: "Liquid sloshing" in new unit.[5]
Cell Quality	"EV Grade-A LiFePO4 Cells"[19]	Fail: "Significant voltage imbalance" (poor cell matching).[6]
BMS Safety	"20+ protections," "short circuit" protection.[20]	Fail: "BMS smoked" during short-circuit test.[6]

V. Long-Term Reliability and Real-World Application Reports

The real-world, long-term consumer experience with LiTime batteries is extremely polarized. It is not a bell curve of "mediocre" 3-star experiences, but a bimodal distribution of 1-star and 5-star outcomes.
On one hand, there is a significant cohort of satisfied long-term users.

One review of a 24V off-grid solar system, after one year of use, was positive enough that the user was in the process of doubling their battery capacity with more LiTime batteries.[44]
Long-term reviews from the demanding marine and fishing community show batteries "holding up" well after 8 months[45] and 1 year[46] of real-world use.
Forum users echo this sentiment, with reports of being "totally happy" after 1 year of use[47] and one user claiming "No problems in 4 years".[48]

On the other hand, a significant and vocal cohort of users reports catastrophic failures, ranging from physical defects on arrival to latent BMS flaws.
This bifurcation implies that the risk is not that the product is mediocre; the risk is that the product is inconsistent. When a consumer receives a "good" battery (one with properly matched cells and a non-defective BMS), it represents a 5-star value that performs flawlessly for years. When a consumer receives a "bad" battery (one with a manufacturing defect, a latent BMS flaw, or poor cell balancing), they face a 1-star outcome. The key variable is manufacturing consistency, which is opaque to the buyer.
The following sections will analyze the "1-star" outcomes, as this is the core of the DIYer's risk assessment.

VI. Analysis of Common Failures and Technical Support Incidents

This analysis of documented user-reported failures provides actionable intelligence for prospective DIY builders.

Case Study 1: The BMS "Bricking" Scenario (LVC Mismatch)

Incident: A user on the diysolarforum.com reported their new 12V 200Ah battery was drained to 8.82V by a small parasitic load from their inverter. The user expected the BMS to perform a low-voltage-cutoff (LVC) at 10V, but it did not.[49]
Consequence: The battery was effectively "bricked." Their Aims inverter-charger required >10V of input to begin charging, so it could no longer "see" or revive the dead battery. Their smart charger also failed to recognize it.
Community Solution: The user had to "jump-start" the LiFePO4 battery by connecting it in parallel to a standard lead-acid battery to raise its voltage.[49] This incident reveals a critical system integration warning. The BMS's LVC is the last line of defense. A DIYer must program their inverter and solar charge controller (SCC) with a higher LVC (e.g., 11.5V or 12.0V) to shut down all loads before the battery is deeply discharged, preventing this "bricked" state.

Case Study 2: The "Parallel Bank" Imbalance (BMS Logic Flaw)

Incident: A user with two new 100Ah batteries connected in parallel found them discharging at wildly different rates. After a few days, one battery showed 27% SOC while the other (connected to the same bus bar) showed 100% SOC.[7]
Community Analysis: This was not a simple cell balancing issue, but a fundamental flaw in the BMS logic.[7] The LiTime BMS has a "Full Charge Protection" (FCP) feature. When triggered (e.g., voltage >14.3V and charge current <3A), the BMS artificially lowers its own terminal voltage by approximately 0.5V.
Consequence: In a parallel bank, the FCP-tripped battery "hangs" at 100% SOC. The other battery is forced to take all the system load until its voltage drains all the way down to match the "hanging" battery's artificially low voltage. This is a non-obvious flaw that actively defeats the purpose of a parallel-balanced system.
Community Solution: The community-sourced solution is highly technical: the user must intentionally program their solar charge controller's absorption voltage to a value below the FCP trigger (e.g., 14.2V or 14.1V) to prevent this state from ever occurring.[7]

Case Study 3: Physical Defects & "Dead on Arrival" (DOA)

Incident: A user on diysolarforum.com purchased two self-heating batteries. Upon unboxing the second unit, they noted "the battery was sloshing whenever I tilted it. There was some sort of liquid sloshing around inside," and they did not install or charge it.[5]
Consequence: This is an egregious QC failure that invalidates all marketing claims about "12-point inspection".[3] It proves that fundamentally defective units are being shipped. The user's subsequent customer service experience (analyzed in the next section) highlights the financial risk of receiving such a unit.

Case Study 4: BMS Failure (Lock-up)

Incident: A YouTuber with a large, 24-battery off-grid system reported that one of the units failed. The "BMS lock[ed] up with low voltage and refusing to respond".[50]
Consequence: This represents the non-zero failure rate of the internal electronics. In a large, expensive bank, a user must assume individual unit failures will occur. The critical question this raises is: What happens when the warranty is invoked?

Table 3: Summary of Reported Technical Issues & Community-Sourced Solutions

Issue	Symptom	Technical Root Cause (as per community analysis)	Community-Sourced Mitigation Strategy
BMS "Brick"	Battery voltage drops below 10V; chargers will not recognize it.[49]	Parasitic load drains battery below LVC; BMS LVC is too low to allow inverter/charger to restart.[49]	Program Inverter/SCC LVC to 12.0V (or higher) to be the first line of defense. "Jump-start" with a healthy battery to revive.
Parallel Imbalance	Batteries in parallel discharge unevenly (e.g., one at 27%, one at 100%).[7]	Flaw in BMS "Full Charge Protection" (FCP) logic artificially lowers one battery's voltage, forcing the other to take 100% of the load.[7]	Do not charge to 14.6V. Program SCC absorption voltage below the FCP trigger (e.g., 14.1V - 14.2V).
BMS Lock-Up	Battery suddenly stops charging/discharging; app unresponsive.[50]	Spontaneous BMS electronic failure.[50]	Attempt to "jump-start" or reset. If it fails, the BMS is likely dead and requires replacement.[12]
Physical Defect	"Sloshing" sound from inside new battery case.[5]	Unknown liquid; catastrophic failure of manufacturing QC.[5]	Do not charge. Contact vendor immediately for return/replacement (within 7-day window).[51]

VII. Customer Support and Warranty Claim Analysis: A Critical Risk Assessment

This analysis concludes that the primary risk of purchasing a LiTime battery is not technical, but financial, and is centered on the company's post-sale support.

Deconstruction of the LiTime 5-Year Warranty Policy

LiTime offers a 5-year warranty on most of its batteries[8], a policy that is central to its value-conscious marketing.[4] However, the warranty policy contains several "gotcha" clauses that provide the company with vectors for claim denial:

The warranty is voided by "Misused, abused, modified, damaged by accident".[53]
It is voided by "Attempted repair by anyone other than an authorized facility" or "disassembly".[51] This is problematic for advanced users who may diagnose a simple BMS failure and opt to replace it themselves.[12]
Critical Exclusion: The warranty "does not apply to the battery cell unless the battery cell is fully charged by you within seven days after you purchase the product and at least once every 3 months".[53] This "charge every 3 months" clause is a significant loophole. It is ambiguous for a battery in a constant-use off-grid system and provides an easy justification for a support agent to deny a claim.

Analysis of Real-World Warranty Claims

The "1-star" consumer experiences, when analyzed in aggregate, show a consistent pattern of adversarial customer support.

Case Study 1: The Reddit 16-Battery Bank Failure[9]
- Incident: A user with 16 LiTime batteries (a significant "prosumer" investment) had a BMS fail at 1.5 years.
- LiTime's Response: The user described it as a "run-around".[10] The support team allegedly engaged in a series of user-blaming tactics, including:
  - Stalling: "Why would they ask me multiple times... about how I charged my batteries?".[9]
  - Confusion: "she thinks I said I was charging... with a power inverter!".[9]
  - Blame: "they are still trying to blame me... saying the pictures show both terminals are BLACK! and that 'I hooked it up wrong'.".[9]
- User's Conclusion: "If your customer service sucks... you really have no warranty at all.".[9]
Case Study 2: The "Sloshing" Battery[5]
- Incident: The user who received the DOA, liquid-filled battery.[5]
- LiTime's Response: Denial. The provided email exchange[5] shows the support team refusing the return, citing suspicion over the timeline because the user reported the defect 2-3 weeks after delivery, not immediately. Forum members noted this was an unreasonable response and the company "should have replaced just the one"[54], demonstrating a company culture of "customer suspicion" rather than "warranty fulfillment."
Case Study 3: The "Bizarre Exchange"[30]
- Incident: A user with a full LiTime system (battery, DC-DC charger, Inverter-Charger) reported 12V loads "flicker" and the system is unstable.[30]
- LiTime's Response: The support agent "continues to believe that I'm just being annoyed by the lights flashing on the unit".[30] This is not a language barrier; it is a failure of technical support. The agent dismissed a critical system stability failure as a cosmetic annoyance, rendering the support channel useless.

External Corroboration: The Better Business Bureau (BBB) "F" Rating

These anecdotal reports of a "run-around" strategy are externally and objectively validated. The LiTime Better Business Bureau (BBB) profile has an "F" rating.[11]
The reason for this rating is not simply "the company receives complaints," as all businesses do. The reason listed by the BBB is: "Failure to respond to 3 complaint(s) filed against business.".[11] This aligns perfectly with consumer reports. It suggests the company's support strategy is one of attrition: to stall, blame, and, if that fails, simply ignore the customer complaint, even when filed with a third-party arbitrator.

VIII. Strategic Assessment and Recommendations for the DIY Builder

Final Risk-Benefit Analysis

Benefit: Market-leading price-per-amp-hour.[42] Independently-verified high capacity (the user gets the amp-hours they pay for).[1] Good feature set (low-temp, Bluetooth) for the price.[40]
Risk (Moderate): Manufacturing Inconsistency. A non-zero chance of receiving a unit with poor cell matching[6], a latent BMS safety flaw[6], or a "lemon" QC failure.[5]
Risk (High): Undocumented Design Flaws. "Smart" features, like the FCP, may be actively detrimental to common DIY builds (e.g., parallel banks).[7]
Risk (Virtually Certain): Adversarial Post-Sale Support. If a failure does occur, the 5-year warranty is effectively void. The evidence strongly suggests the user will face a support team that misunderstands[30], blames[9], or ignores[11] their claim.

Identifying the "Ideal" LiTime Customer vs. the "At-Risk" Customer

The "Ideal" LiTime Customer: A technically proficient "Advanced DIYer" who:
1. Treats the battery as a component (cells + BMS in a box), not a "solution."
2. Is technically capable of diagnosing and replacing a failed BMS themselves.[12]
3. Is building a simple, single-battery system (thus avoiding the parallel bug[7]).
4. Is willing to "self-insure" the purchase, accepting the full cost as a loss if a failure occurs.
The "At-Risk" Customer: The "Beginner DIYer" or "Set-it-and-forget-it" user who:
1. Is building a large, complex, parallel-connected bank.[7]
2. Requires high-reliability (e.g., for critical home backup).
3. Believes the 5-year warranty[8] and "Grade-A" marketing[4] will protect them. This user is being set up for financial loss and significant frustration.

Mitigation Strategies for Potential Purchasers

Purchase Channel: Consider purchasing from a third-party vendor with a robust, "no questions asked" return policy (e.g., Amazon) rather than from the LiTime direct website. This mitigates the risk of receiving a DOA unit[5] or one that fails in the first 30 days.
Immediate Testing: Upon receipt, immediately (within the 7-day no-reason return window[51]) inspect for physical defects[5] and perform a full charge/discharge capacity test.[1]
System Design (Parallel): If building a parallel bank, you must consult community "tribal knowledge"[7] and program your solar charge controller's absorption voltage below the FCP trigger (e.g., 14.1V or 14.2V) to prevent the uneven discharge bug.
System Design (LVC): Program your Inverter and SCC's Low-Voltage-Cutoff settings higher than the BMS (e.g., 12.0V) to be the first line of defense and prevent the "bricking" scenario.[49]
Warranty: Assume the 5-year warranty is a marketing talking point, not an enforceable contract. The real warranty is the money you saved, which you may have to spend on a replacement BMS[12] or a replacement battery.
