Constant current/constant voltage (CC/CV) with protection module TP4056 and DW01A IC. When the voltage is lower than 2.4V, it triggers over-discharge and power-off. When the current exceeds 3A, it triggers short-circuit and power-off. When the voltage is lower than 3.0V, the release voltage is released. A trickle charging current of 130mA will be used to repair the battery.
