pack
oAdjustable Charging voltage from 54-75VDC
oMust select charging voltage correctly based on battery used below
Li-Ion / LiMnNi = 4.2V / cell
Ex. Charging voltage for 51.8V (14Cells) Li-Ion/LiMnNi = 4.2V
x 14 = 58.8V
LiFePO4 = 3.55V / cell
Ex. Charging voltage for 51.2V (16Cells) LiFePO4 = 3.55V x 16
= 56.8V
SLA = 2.43V / cell
Ex. Charging voltage for 48V (24Cells) SLA = 2.43 x 24 =
58.32V

•UL / CE listed
Charging cycle:
Stage 1: Constant Current Mode (CC):
The charger changes to constant current 18A+/-0.5A. When the
battery voltage reaches up to 54-75VDC (Based on voltage selection),
the charging stage changes from CC (Constant Current) to CV
(Constant Voltage) mode.
Stage 2: Constant Voltage Mode (CV):
In this stage the voltage of each cell in the battery is
equalized.The charger holds the battery at 54-75VDC (Based on
voltage selection) and the current slowly reduces.
