One Set Button intuitive programming for Charger and DC source Mode.
The programmable charger design for Lithium base batteries with constant monitoring of the battery state so that it can be connected to the battery at all times.
Selectable for Lithium Ion group (NMC, NVA, LCO, LMO) and LiFePo4 type battery or DC Source Mode.
Soft Start charging to ensure gentle initial charging of deeply depleted batteries and charger will return to normal charging once battery state of charge picks up.
10%/ 25%/ 50%/ 100% Max Charging Current selections allow an optimal charging current for a wider range of battery capacities.

4 Stage Charging Profile

Battery Type Batt. Volt V-Low Batt. Volt V-Normal Bulk/ Absorption V Float V (ON) Recycle V level
Lithium Ion 12V/ 24V: 10.2V/ 23.8V 10.8V/ 25.2V 12.6V/ 29.4V 12.2V/ 27.2V 10.8V/ 25.2V
LiFePO4 12V/ 24V: 12.6V/ 23.2V 12.8V/ 23.6V 14.6V/ 29.2V 13.8V/ 27.0V 12.8V/ 23.6V

The maximum time period for Absorption Charge or end of Boost Charge prevents abnormal or faulty batteries continuously drawing current from the charger under high voltage condition.
The Float Charge can be set to ON/ OFF to cover various BMS (battery management system) and operating conditions of the battery.
Thermo fan cooling and works with supplied battery temperature sensor for high temperature limiting charge current to 3A at 60°C
self recoverable when temperature returns to about 45°C.
Low Temperature Protection : at minus 2°C charge current drops to 3A and returns to normal at minus 0.5°C.

The DC Source Mode
Output Voltage adjustable from 10.6V to 14.6V by 1 volt step & 0.1volt step.
Max Output Current adjustable by 10%/ 25%/ 50%/ 100%.
