Charging Parameters
Rated voltage	2V	N	N stands for different rated voltages, the variable for battery charging voltage is based on the value of 2V. For example, if the rated voltage is 360V, the overvoltage disconnect parameter value is 360V/2V*2.65V=477V.
Overvoltage disconnect	2.65V	=2.65*N/2
Overvoltage reconnect/complete charge	2.5V	=2.5*N/2
Equalization charge	2.4V	=2.4*N/2
Float charge	2.3V	=2.3*N/2
Equalization charge recovery	2.2V	=2.2*N/2
Under voltage alarm	1.75V	=1.75*N/2
Equalization charge timing	120 min
Charge current limiting	＜ rated current
All charging parameters are adjustable by users based on the battery properties The charging parameters for lithium battery need to be customized according to the properties of the lithium battery Charge current limiting can be set by users with a value less than rated current
