After I rode my board, I took off the enclosure because I needed to charge up my 2 Turnigy 5Ah 3s Lipos.
I immediately noticed only one of the 3s batteries was puffy. What would cause only one to puff up? Could it have to do with the fact that I charge them separately as 3s packs? The cells on the puffy one are at 2.8v/cell but when I plugged the not puffy one into the charger it showed 3.6v/cell. I am using an FVT120a ESC with the e-board firmware which doesn’t let you select the LCV
Isn’t this theoretically impossible in a series circuit like the because the ESC pulls from the cell with the highest potential?
Also, now I don’t know what to do. I probably shouldn’t use this battery anymore, but can I just go buy 1 3s pack, or do I have to have a matching set? The set only has about 8 cycles on them
