Hey Guys, having an issue with my JBD 120A 4S. When charging one cell reads higher than the others, genrally around 0.02 amps when charging at less than 10a. However when charging at higher than 15a cell #3 takes off to the point where its constantly hitting the over charge limit (3.55v). As soon as it hits the limit charging stops and the cell drops back to 3.35ish with the rest of the cells (at rest theres no difference). When charging resuems the cycle continues. Thinking it could be a dud cell I tried swapping around cells, and bus bars; bascially changed up the pack however its the same #3 position cell on the BMS that spikes which leads me to think its the BMS and not the cells themselves. Tried replacing connector on the #3 cell but no difference in reading. ANy ideas on what else I can check before binning the BMS? Ive got no other BMS's to test the pack with.
