I have a universal lead acid charger with high charging current; can I use it instead to charge LiFePO4 batteries?
AUKPower does not recommend using lead acid chargers for LiFePO4 batteries. Lead acid batteries charge at 2.30V to 2.45V per cell whereas LiFePO4 batteries require 3.60V per cell. Your battery would potentially be undercharged, so you will not get use of the full capacity of the LiFePO4 battery, nor will balancing be triggered in the LiFePO4 battery pack, both of which are not desired. Furthermore, the floating charge of the lead acid charger is not expected by the battery and can cause problems. We recommend purchasing the battery with the bundled charger.
