电池保护电路

每次更换电池,都会导致电池保护电路锁死。(缺少一颗电池的瞬间会使保护电路认为缺少的那颗电池已经坏了,从而锁死整个供电)。更换完后,要按一下图中的按钮S2或者插一下充电器,重新启动保护电路。

At the moment you remove any cell of the battery, the protect circuit consider the cell has been failed, so halt up all the power supply. You need press S2 once to re-start the protect circuit. Or plug the charger for one second to re-start the protect circuit.
