Charging Process

Boost charge: Charge according to the maximum current until the battery voltage reaches the constant voltage charging voltage.
Constant voltage charging: When the battery voltage rises to a boost charging voltage, the current begins to fall and enters constant voltage charging for 2 hours.
Voltage Adjustment: When the battery voltage is > 12.6V, the constant voltage charging is cancelled and the floating charging is directly charged.
Floating charge: After constant voltage charging is completed, the floating charging starts, the current decreases, and the battery maintains the floating charging voltage.
