Note
Phase I： CC (Constant current)
B. Charging Mode
Method 1: Battery charger
Recommended charging voltage: 14.2V to 14.6V
Recommended charging current:
Use a dedicated 14.6V LiFePO4 battery charger to maximize the
battery's capacity.
The 20A (0.2C) battery will be fully charged to 100% capacity in about 5 hours.
The 50A (0.5C) battery will be charged in about 2 hours at 97% state of Charge.
Initially, a discharged battery will be charged at a constant current, and
the voltage will rise steadily until it reaches a constant voltage point,
which varies with different charging method.
Phase II: CV (Constant Voltage)
In this phase, the battery maintains a constant voltage while the current
rating drops to 2A (0.02 c), which is also known as constant current mode.
To accurately test the battery's real voltage, disconnect all connections
and measure it after resting for over 30 minutes. The expected true
voltage should be around 13.4V.
