Charging Batteries
A specific LiFePO4 battery charger is required to charge the Neuton Power LiFePO4
batteries. Chargers that require the detection of voltage may fail to wake the LiFePO4
battery from a state of under-voltage protection. Constant Voltage (CV) chargers
may result in an inrush current due to the low impedance of the cells,
interrupting the
charge. Reset the charger and continue charging normally if the charger trips.
The constant current (CC) charger is strongly recommended.
To charge a single 12.8V battery, the maximum charge voltage is 14.6V and the maximum
charge current is referred to Table 1. Any inrush current may cause over current or short
circuit protection.
Once you reach end-of-charge voltage, apply a constant voltage, and hold at this voltage
until the current decays to almost zero. This charges the cells to 100% state of charge
(SOC). Refer to below figure for an illustration.
