Tool/software:
Hi,
I setted up as below battery and charging voltage & current.
The device works well to change CC mode to CV mode, but it started current swing at close to termination current. (not touch to thermination current)
- Supply voltage : 24V
- Charging voltage 28.99V
- Charging current : ICHG_REG : 4.5A / ITERM : 500mA
- Battery : Li-ion 25.41Vdc(7S2P)
