I just finished my electric skateboard and tested it yesterday. It was a lot of fun until my battery ran out. I have 2 3s batteries and 1 2s battery. I went back inside to check the voltage on the cells and found out that on my 2s battery the voltage is 3.7. One of my 3s batteries had 3.4v on each cell. The other 3s battery cell number one had 2.96v cell number 2 had 3.31v and cell number 3 had 3.28v.
Does anybody know how my cell went down to 2.96v. my 2s battery used to be a 3s but one cell died. I hope somebody can help me before i lose another cell
