The protection board has over charge protection function, over discharge protection function, over current protection function and short circuit protection function.
Board charging and discharging are the same port, board is included balanced circuit.
When the charge balance, the board will be a bit warm, even after disconnecting the charger, some are still in balance, will continue to warm for a while until below the equilibrium break threshold.
The protection board can not be used for iron lithium polymer battery (for other batteries, no matter what material, as long as the overvoltage and put voltage can be used for cutting), electric fishmachine batteries, electric bicycle batteries, car and motorcycle starter battery protection.
