7. BATTERY CHARGING

7.1. When to Charge your LiFePO4 Battery

If LiFePO4 batteries are not fully discharged, they do not need to be 
charged after each use. LiFePO4 batteries do not get damaged when 
left in a partial state of charge (PSOC). You can charge your LiFePO4 
batteries after each use or when they have been discharged up to 80% 
(20% SOC). If the BMS disconnects the battery due to low voltage, at 
100% depth of discharge, remove the load to reconnect the battery 
circuit and charge immediately. Please note that we recommend storing 
batteries at 50% state of charge (SOC).

7.2. Charging Temperature

Lithium Iron Phosphate batteries generate a fraction of the heat of other 
lithium chemistries making them very safe. LiFePO4 batteries can safely 
charge between -4°F to 131°F (-20°C to 55°C). However, at temperatures 
below 32°F (0°C) the charge current must be reduced as follows:
1.   32°F to 14°F (0°C to -10°C) charge at 0.1C (10% of the battery 

capacity)

2.  14°F to -4°F (-10°C to -20°C) charge at 0.05C (5% of the battery 

capacity)

LiFePO4 batteries do not require temperature compensation for voltage 
when charging at hot or cold temperatures. All RELiON LiFePO4 come 
with a BMS that protects the battery from over-temperature. If the 
BMS disconnects due to high temperature, wait until the temperature 
reduces and the BMS reconnects the battery circuit before using or 
charging the battery. Please refer to your battery data sheet for BMS 
high temperature cut-off value.
