I started building some 18650 batteries. I'm quite familiar with almost every about them but I'm not sure of one thing.
I know that when charging one 18650 cell the cutoff current is around 50ma + or -. How does that translate when you have a large bank. Say you have 10 in parallel. You could assume that would be 10 x 50ma, or 500ma. But what if you have 100 in parallel? I wouldn't think that you would stop the charging when the current gets down to 5 amps?
How does that work out with such a large bank?
How does it work when you have a large series bank also?
Any thoughts on this will be appreciated!
Thanks, Ken
