For pack builders
Use a BMS/PCM with overcharge, over-discharge, overcurrent, over-temperature, and short-circuit protection. The protection circuit should monitor each cell and stop charging or discharging when limits are exceeded.
For long storage, keep cell voltage between 3.50V and 3.95V. Recharge periodically to prevent over-discharge. Follow the datasheet for charge and discharge temperature limits.
