How to calculate charging voltage for battery? Normally single cell charging voltage for li-ion is 4.2V, and single cell charging voltage for LiFePO4 is 3.65V; Single cell(12V) charging voltage for lead acid battery is 14.7V, therefore charging voltages for batteries are as follows:

24V LiFePO4 battery (8 cells in series): 8x3.65V=29.2V;

24V Li-ion battery (7 cells in series): 7x4.2V=29.4V;

24V Lead acid battery (2 cells in series): 2x14.7V=29.4V

36V LiFePO4 battery (12 cells in series): 12x3.65v=43.8V

36V Li-ion battery (10 cells in series): 10x4.2v=42V

36V Lead acid battery (3 cells in series): 3x14.7v=44.1V

48V LiFePO4 battery (16 cells in series): 16x3.65v=58.4V

48V Li-ion battery (13 cells in series): 13x4.2v=54.6V

48V Lead acid battery (4 cells in series): 4x14.7v=58.8V

60V Lead acid battery (5 cells in series): 5x14.7v=73.5V

If your battery is different voltage, please inform us. Or if your battery is with different cells number in series, you can calculate the charging voltage yourself.

The lead time for the charger is about 2-5 days because different customers have different demand for the charging voltage and we need a few days to set and test before shipping.
