With protection board function. Function introduction: When the charging current drops to 100mA after reaching the final floating charging voltage, the charging cycle will be automatically terminated. When the battery voltage drops below 4.05V (approximately 80% to 90% of the battery capacity), the charging cycle starts again. When the battery voltage is lower than 2.9V, the battery will be pre-charged with a current of 100mA. With protection plate, overvoltage protection, over-discharge protection and over-current protection. Overdischarge protection value: 2.4V; Overcurrent protection value: 4A. For the first use, connect the power supply to activate the protection board.
