4. USE OF THE LIFEPO4 BATTERY PACK
4.1 Charging
• LiFePO4 batteries do not need to be recharged after each use, leaving them in a partially char-
ged state is not harmful to the battery.
• The battery can be charged with high charging current to shorten the charging time, max.
charging current per battery, see data sheet
• If the BMS disconnects the battery due to low voltage to protect against deep discharge, the
battery should be recharged as soon as possible. Otherwise, the cells could be permanently
damaged.
• LiFePO4 batteries can be safely charged in the temperature range 0°C - 55°C.
• Charge with any IU charger that does not exceed a final charge voltage of 14.6V or with a
charger with LiFePO4 characteristics.
• The BMS switches the battery off if it gets too hot. When the temperature drops, it automati-
cally switches the battery back on.
• If necessary, the cells are balanced automatically during charging or during a standby phase.
4.2 Discharging
• Discharge up to 100% of capacity is possible, but a discharge of max. 90% is recommended.
• Safe discharge in the temperature range -20°C to 60°C.
• The BMS switches the battery off if it becomes too hot. When the temperature drops, it auto-
matically switches the battery back on.
