Charging Process
1
Boost Charge: Charges at maximum current until battery voltage reaches the constant voltage level based on battery parameters.
2
Constant Voltage Charging: When boost voltage is reached, current falls and constant voltage charging continues for 2 hours.
3
Smart Bypass: If battery voltage is > 12.6V, constant voltage charging is cancelled, moving directly to floating charge.
4
Floating Charge: After constant voltage phase, current decreases while maintaining the floating charging voltage.
