Charging Process
 

1. . Boost charge: Charge according to the maximum current until the battery voltage reaches the constant voltage charging voltage. Different battery boost charging voltages refer to the battery of charging parameters
2. . Constant voltage charging : When the battery voltage rises to a boost charging voltage, the current begins to fall and enters constant voltage charging, and the constant voltage charging time is 2h
3. When the battery voltage is> 12.6V, the constant voltage charging is cancelled and the floating charging is directly charged
4.  Floating charge : After the constant voltage charging is completed, the floating charging starts, the current decreases, and the battery voltage maintains the floating charging voltage. Reference charging parameters
