💡 Charging Process Overview
The Smart Battery Charger uses a fully automatic 4-step process. The Pre-charge step activates low voltage batteries and protects extremely discharged units. The CC step charges with Constant Current at high speed. The CV step uses Constant Voltage as the current drops, and finally, the Floating step maintains 100% capacity with a small trickle charge, preventing overcharge.
