4.6. Series or Parallel Connections
When connecting batteries in series or parallel, please make sure each battery is within 50mV (0.05V) of each other
before putting them in service. This will minimize the chance of imbalance between batteries. If your batteries get out
of balance, the voltage of any battery is >50mV (0.05V) from another battery in the set, you should charge each battery
individually to rebalance. Please reference RELiON's LiFePO
relionbattery.com) for series and parallel charging.
5. Battery Storage
5.1. Storage Temperature
LiFePO
batteries can be stored between -20°C to 60°C (-4°F to 140°F).

5.2. Storage Conditions
Store batteries at 50% SOC to minimize irreversible capacity loss.
If batteries are stored for long periods of time, cycle the batteries at least every 6 months.
6. Battery Discharging
6.1. Discharge Temperature
Lithium Iron Phosphate batteries generate a fraction of the heat of other lithium chemistries making them very safe.
LiFePO
batteries can safely operate between -20°C to 60°C (-4°F to 140°F). All RELiON LiFePO
4
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.
6.2. Discharging your LiFePO
LiFePO
batteries can be discharged up to 100% of their capacity. However, to optimize the performance of your LiFePO
4
battery, and to avoid the BMS disconnecting the battery circuit, we recommend limiting the discharge to 80%. Please
refer to your battery data sheet for the continuous and peak rates of discharge for your specific battery model.
7. Battery Charging
7.1. When to Charge your LiFePO
If LiFePO
batteries are not fully discharged, they do not need to be charged after each use. LiFePO

damaged when left in a partial state of charge (PSOC). You can charge your LiFePO
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) to minimize irreversible capacity loss.
