So just expanding thIs again for comment... if I ran 10 3000mah matched IR 18650 cells in parallel, that would give me a 1s 30ah pack. If I link that to an identical one in series, I end up with a 2s 30ah pack. As long as I set up a balance connection to charge each individual 1s bank of cells, I could end up with a 2s pack I could balance charge effectively on my 4010 iCharger.
If each individual cell had a 20A rating does, does this increase linearly with cell count ie 10x20=200A or am I completely wrong here?
