Safety Guidelines & Warnings
⚠️ IMPORTANT NOTICE ⚠️
All rechargeable batteries require proper handling, charging, and storage. Misuse can result in fire, explosion, injury, or property damage.
General Safety Guidelines
✔ Only purchase and use if you understand the safety requirements for the specific battery type.
✔ Always charge using the correct charger designed for the chemistry of your battery (LiFePO4, Li-ion, NiMH, etc.).
✔ Store in a cool, dry environment away from heat, direct sunlight, or flammable materials.
✔ Follow the manufacturer’s specifications for voltage, current, and temperature.
✔ Use a Battery Management System (BMS) where required to ensure safe operation.
✔ If assembling packs, ensure proper balancing and testing before use.
✔ Resellers must pass these safety warnings on to end users.
