🔒 1-Year Warranty
We stand behind the quality of our LiFePO₄ (LFP) cells and offer a 1-Year Warranty that covers manufacturer defects. If your battery experiences a verified factory defect within this period, we will provide a replacement.
Terms:
Warranties apply only to the original purchaser and are non-transferable.
Warranty claims require proof of purchase, serial number verification, and test results.
A properly configured BMS is mandatory. Warranty is void if a BMS is not used or misconfigured.
✅ Covered Manufacturer Defects:
Internal short circuits due to factory defects.
Electrolyte leakage (not caused by physical damage).
Cells failing to meet advertised capacity under proper use.
Factory defects in welds or terminals.
❌ Not Covered:
Overcharging, over-discharging, or exceeding rated current.
Failure due to lack of a proper BMS or incorrect BMS settings.
Cells installed into pre-existing battery packs where failure results from pack imbalance or BMS issues.
Physical damage, including punctures, crushing, or exposure to heat/water.
Natural capacity fade due to aging and cycle life.
⚠ Important Safety Warnings
Improper handling or misuse of this Lithium Iron Phosphate (LFP) battery can result in ELECTRICAL DAMAGE, FIRE, or THERMAL RUNAWAY, causing personal injury, property damage, or equipment failure. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.
- Voltage Limits: Always operate within the recommended voltage range (2.5V–3.65V). Exceeding these limits can degrade performance, damage the cell, or pose safety risks.
- Thermal Stability: LFP cells are thermally stable, but short circuits, overcharging, or physical damage can still cause overheating or failure.
- Storage & Transport: Always store cells in protective cases or fully assembled battery packs with proper protection circuitry (BMS). Never store loose cells in bags or near conductive materials (e.g., tools, wires, or metal objects) that could contact the terminals and cause a short circuit. Store in cool, dry conditions away from physical or electrical hazards.
- Inspection: Do not use if the battery casing, wrapper, or terminal is damaged, dented, leaking, or bulging. These are signs of instability and potential failure.
- Charging: Use a smart charger specifically designed for LFP cells and ensure that the charger's voltage matches the battery's specifications. Monitor charging and avoid leaving batteries unattended.
-
Prohibited Activities:
- Do not expose the battery to high heat, fire, or liquid.
- Do not short circuit, puncture, crush, or modify the cell.
- Do not charge or discharge beyond the manufacturer’s specified voltage range.
- Do not dispose of in regular trash—always recycle responsibly.
- Emergency Response: If the battery overheats, emits smoke, or swells, move it to a non-flammable surface (e.g., sand or concrete) and stop use immediately. In case of fire, use a Class D fire extinguisher or sand. Do not use water.
