Hello,
I have a pool robot that runs on batteries and stopped working. I took it apart and found the battery pack.
The label states 10.8v and it has 6 cells so I assume 3S2P. I also checked how the batteries are connected and it fits the 3S2P layout.
The readings are a bit off though:
- When I check each pair of cells individually I get 4.1v.
- When I check over the 3 x pairs I get 12.3v.
- But when I check via the BMS chart/discharge port, then I only get 4.1v.
This leads me to believe the BMS is faulty. Does that make sense?
Thanks!
