I got a hold of some pretty high quality genuine Sony Murata 18650 cells for a project. I know each cell has a 30A max output capability but will the cells be damaged if I run them in series of 3 for just over 12V charged and then pull 70ish amps through all of them simultaneously? Or will the resistance of each cell cause overheating?
I'm hoping to run an inverter on them and I figured 4.2V x 3 = 12.6V with 90A so 1134W then I thought no, that's stupid, it's probably 4.2V per cell @ 30A = 126 watts per cell times 3 = 378 watts max. So let me know if that second one is more accurate and if it's safe to run that many amps through each cell if they're in series of three. I have enough cells to make 3-4 parallel lines of 3 in series for a 400W inverter if that's safer.
