PCM or PCB ( protection circuit module or board ) is the “heart” of the Lithium battery pack. It will protect the Lithium battery pack from overcharging, over-discharging and over-drain, therefore it is a must to have to avoid a Lithium battery pack from the explosion, fire, and damage. A Battery Equalizer is a specialized DC-DC converter, designed to convert electrical power from one voltage to another at high efficiency. They’re used to balance battery loads in dual voltage systems.
