  The PCM ensures the safe operation of the battery by providing protection against overcharge, over-discharge, overcurrent, and short circuit conditions. This helps maintain the battery’s health, extend its lifespan, and prevent potential damage. The Blue Square designation likely refers to the specific design or appearance of the module, which could indicate a particular brand or series of protection modules. This PCM is typically used in 4-series LiFePO4 battery packs, offering an optimal balance of protection and power handling for various applications.
