This charging board has built in under/over voltage protection circuits for safe charging and battery longevity. It balances different voltages between batteries in case one battery discharges faster than the other ones. A 19 VDC, 1-5A power adapter works best for charging batteries contained in this board.

Failing to do so will prevent the amp board from powering up. Specifications: ? Included cable: 8" 4-conductor ?
