Charging Parameters

The variable "n" is a multiplying factor for parameter voltages based on battery system voltage (12V: n=1; 24V: n=2; 36V: n=3; 48V: n=4). Example: Equalize charge voltage for 12V FLD is 14.8V*1=14.8V; for 24V FLD is 14.8V*2=29.6V.

Activate Lithium Batteries

To enable lithium battery activation, set the battery type to ALI. When the connected lithium battery voltage is 0V, the activation function triggers automatically. The controller activates the battery at a constant voltage of 14.4V (12V systems), 28.8V (24V systems), 43.2V (36V systems), or 57.6V (48V systems).

After constant charging, the LCD will display "AALI". Activation is successful when charging current exceeds 300mA, and the controller exits activation mode.
