Safety & Maintenance Warnings

BMS Required: The label explicitly states it must be used with a compatible Battery Management System (BMS) only. A BMS is critical for balancing cells and protecting against overcharging or short circuits.

Handling: Do not short circuit, disassemble, crush, or incinerate. Keep away from fire and water to avoid thermal runaway or explosion risks.

Storage Tip: For maximum lifespan, follow the "40–80 rule," keeping the state of charge between 40% and 80% when not in use.
