High Power selectable charger 24V/20A for LiFePO4 and LTO batteries with BMS support.



GWL/Power industrial battery charger for lithium batteries with DIP switch for setting of proper voltage level of LFP or LTO cells.
You can set easy the charger to 4 LFP cells, 10 or 12 pcs of LTO cells. It means the 24V nominal voltage of the battery pack.

Main Specification:
  • Input AC 230V (Power cable to Grid is included in package)
  • Output DC 26,5V/29,2V/30,4V
  • Over-voltage protection
  • Protection anti short circuit and reverse polarity
  • Timing protection for failure of charge
  • LED indicator of charging status
  • Active cooling - fan
  • BMS option - connector for connect to the BMS (Battery Management System)
  • Small size and low weight

Application notes: Even though this charger is designed as a fully automatic charger, it is always recommended to operate this charger under continuous supervision and with additional monitoring of the charging parameters for the battery pack. It is necessary to make sure the cells of the battery pack will not be over-charged or misbalanced. We also suggest installing over temperature and fire protection alarms.

Check our GWL Technology Blog to know more about the propper charging characteristics of LiFePO4 battery.

Please see how to set the charger.




Please, make sure that you have set these DIP switches according to your battery chemisty (in case LTO, you have to set 10 or 12 cells)



Connecting charger BMS with BMS123


Charger includes the management connector for BMS. BMS system should control the charging process. There are three states for BMS:

  1. Full charging 20 A
  2. Slow charging 5A
  3. Stop charging 0A

Charger is also fully automatic for stand alone using without BMS connection with advanced processor-controlled lithium battery charging process for 24V nominal voltage. This GWL/Power charger is an industrial battery charger for lithium batteries, that allows charging the lithium cells in a safe and reliable way.


For disconnect charger via BMS123:

connect black (GND) from charger to pin 2 on OUT board on charge relay contacts.
connect Brown (ON/OFF) from charger to pin 3 on OUT board on charge relay contacts.

For reducing charge current via BMS123:

connect black (GND) from charger to pin 2 on OUT board on charge relay contacts.
connect Blue (HIGH/LOW) from charger to pin 3 on OUT board on charge relay contacts.
