Hello everyone. Today I faced the problem that I hoped I will never face. Overdischarge.
This morning I went to the fridge to get out my lipos for my board from there. I am using 4x 3s 5Ah lipos from HRB to be specific. Then i decided to check all of the voltages and faced the problem: the 4th pack’s 3rd cell voltage was at 1.36V. In other words, it was dead.
I managed to restore it using the IMAX b6 in NiCd mode at 0.1A. Well, I know that it is dangerous as f…k, but I’ve did it anyway.
So now I actually dont know what to do:
-1: I can try to use it in my old setup 6s2p (with one half-dead cell) at my own risk
-2: I can replace this cell just by buying single cell from the HRB. (but it will have higher capacity, which is not good either)
-3. I can desolder this cell as well as one good cell and build my own 10s lipo pack.
-4. I can swap to the absolutely new li-Ion pack but this is an overkill IMO.
So what do you guys think? What should I do?
