Applications

  • This DC Power supply can be used as a charger to test the following:
    • Li-Ion battery pack up to 1 -7 cells in series ( 25.9V max. ) per Channel (strongly recommend to have pcb or pcm install in the pack before charging).
    • LiFePO4 battery pack up to 1 -8 cells in series ( 25.6V max. ) per Channel. (strongly recommend to have pcb or pcm install in the pack before charging).

Warnings

To charge a Li-Ion pack safely:
  • Must set up constant voltage correctly, e.g Charging Voltage = 4.2V x Number of Li-Ion Cell in series, or 3.65V x Number of LFP Cell in series
  • Must set up constant current equal or less than specified charging currentper cell
  • Too highcharging voltage may cause Li-Ion battery explode
