Prototyping and Engineering Tips from Robogears:

Always charge the battery using a dedicated 4.2V Li-ion charger or a compatible Battery Management System (BMS).
Never short-circuit, puncture, crush, or expose the battery to excessive heat or fire.
When building multi-cell battery packs, use matched cells of identical capacity and age along with an appropriate BMS for safe charging and discharging.
Store the battery in a cool, dry place and avoid complete discharge to maximize cycle life.
