Recommended Charging Parameters Table for Lithium Iron Phosphate
Batteries
Note: "Overcharge Protection Voltage” and "Overcharge Recovery Voltage" in the table above
refer to typical parameters in the BMS or battery protection board and are for reference only.
The "Charging Voltage" corresponds to the Boost charging voltage of the controller, the
"Over-discharge Recovery Voltage" corresponds to the over-discharge recovery of the
controller, and the "Over-discharge Voltage" corresponds to the over-discharge voltage of the
controller.
