Back to the battery
So in another thread, I mentioned that the 36V 10Ah LIPO battery on my bought used Xtreme Baja folding wasn't taking a charge. Charger goes red for about 15 minutes and then shows green again.
Total battery voltage after charging reads 39.4v. So I took the battery out of the metal slide-in case, removed the blue shrink wrap and found 40 cells LS LR1865SZ which aren't LIPO, they're lithium ion.
After testing the cells, I found various voltages, some cells read 3.8V, some cells read 4.0 or 4.1V and four cells read 3.2V. Am I right to think that I should change out the 4 cells that are at 3.2V and see if
the BMS will balance and charge all the cells to 4.2. I would just cut the nickel strips and solder new ones in since I don't have a spot welder. Finding 4 similar speced batteries for $10-15 (maybe less) total shouldn't be a problem.
I'm thinking this might get the battery back up to 42 volts when charged. Any thoughts?
