Does a lithium battery need a charge management module if it has a protection board?

Required. Due to the characteristics of lithium-ion batteries, they must be equipped with a protection board (PCM) or battery management system (BMS) before they can be used. Lithium-ion batteries with protective plates also require a charge management module. It is strictly prohibited to use lithium-ion batteries without protection plates or a battery management system. Without protective panels or battery management systems, lithium-ion batteries pose a safety hazard and even cause fires or explosions. Safety is always the first priority when it comes to batteries and battery management systems.
