Today I made my battery pack ready to test if the pack would charge with my BMS.
- 12A max charging current
- 20-26V input
- 24V adjustable so I had to adjust it to 25.5V
- Max 300W so the power supply can give enough current
Batteries: 6S2P 222Wh pack
The batteries are nicely balanced due the BMS because when the cells arrived, the voltages of the cells weren’t exactly the same and after connecting the BMS, every cell is 3.72V so that’s a good sign I guess. I connected everything like it should, but the battery is not charging. Also the fan of the power supply is turning but it doesn’t get warm the touch. I guess the problem is the power supply but I don’t know why. Anybody who might know why this isn’t working?
