Below is a list with battery cell combinations and charging voltages so to select the proper charger.

Normally single cell charging voltage for Li-ion is 4.2V
Single cell charging voltage for LiFePO4 is 3.65V
Single cell 12V charging voltage for lead acid battery is 14.7V

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

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

24V Li-ion battery (6 cells in series): 6x4.2V=25.2V

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 (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
