CHARGING INSTRUCTIONS
Charging with an Inverter or Charge Controller Charger
Inverter and Charge Controller Charge Parameters
Below are the typical charger inputs when using an inverter or charge controller with LiFePO batteries. LiFePO batteries do
not require equalizing. LiFePO batteries do not require temperature compensation for voltage when charging at hot or cold
temperatures.
CHARGE PARAMETER 12V SYSTEM 24V SYSTEM 48V SYSTEM
Bulk Voltage 14V – 14.6V 28V - 29.2V 56V - 58.4V
Absorption Voltage 14V – 14.6V 28V - 29.2V 56V - 58.4V
Absorption Time 0- 15 min 0- 15 min 0- 15 min
Float Voltage 13.3V - 13.8V 26.6V - 27.6V 53.2V - 55.2V
Inverter or Charge Controller Voltage Parameters
VOLTAGE CUTOFFS 12V SYSTEM 24V SYSTEM 48V SYSTEM
Low Voltage Cuto 11V - 12V 22V - 24V 44V - 48V
High Voltage Cuto 14.6V 29.2V 58.4V
Charging with an Alternator
Depending on the quality of the alternator it may work fine with LiFePO batteries. However, the current and voltage spikes
associated with lower quality alternators or with high loading, can cause the BMS to disconnect LiFePO batteries. If the BMS
disconnects the batteries the alternator may be damaged. To protect your LiFePO battery and alternator please be sure to use a
compatible high-quality alternator or install a voltage regulator.
