Chargers for 48V Lithium ion Batteries Battery Chargers for Lithium ion batteries that 13 cells connected in serial. This kind battery may be called 48V battery, with maximum voltage 54.6V.
When select battery charger, please also make sure the charger maximum output current is within your battery charging current limitation. If you do not have specifications for your battery charger limitation, it is recommended to choose a charger that its maximum output current is 1/3 or less of battery maximum Ah capacity. For example, for a 48V 9 Ah lithium ion battery, it is recommend to choose a charger with maximum output current 3 Amps or less, maximum voltage 54.6V. Using smaller charging current to charge a lithium ion battery will take longer charging time, but it will be better for battery.
