2. Two Core Functions

1. Smart charging function
Three-stage fully automatic charging: constant current fast charging → constant voltage equalizing charging → gradual current floating charging. The device automatically stops power supply when fully charged to prevent battery overcharging and swelling; it features multiple safety protections against reverse connection, short circuit, and overheating. The wiring clip can be used in the reverse direction without damaging the machine.
