Hello guys,
I have a problem with my LiHV battery. When I charge it it starts normally, voltage level is continuously increasing, and after it reaches around 4.2V on the cells, the first cell internal resistance jumpes and reaches lvl 122 mOhms, my all cells at the beggining level is (44, 8, 40) Ohms, but after this IR jump is (122, 8 40). I use some ballancing board and self made connectors to use my charger - maybe its the reason of slightly high resistance level, but it is not explaining why internal resistance rises only on first cell. I have few batteries and not all of them have this problem.
Also the reading is fake then - it says 3,8V on first cell, I noticed that when discharging, it back to primary resistance, when other cells have 4.2V, then the first one also shows 4.2V, even though at the beggining it was 3.8
Anyone seen something similar before?
I have no idea why it behaves like that.
