away from batteries. If this charger is used with lithium-ion type batteries, an integrated battery
management system (BMS) must be used. The BMS must ensure that in all operating modes, the battery
cells are protected from inappropriate levels of voltage, current, temperature, and state of charge. Do not
operate the charger in a closed-in area or restrict ventilation. Never charge a frozen or non-rechargeable
battery. Obse
rve all battery manufacturers’ precautions (e.g., maximum charge rates and if cell caps
should be removed while charging).
