So, I have spent several weeks (thanks to Covid,we can't go out much) building a trolling motor battery from salvaged 18650 laptop batteries.
Individually charge, test, pass or fail, until I got 240 cells at 2000maH or better.
I now have a 60p 4s pack.
My question is . . . How do I charge it ?
To charge single cells, I use is a CC CV 4.2v 1A lab supply.
To charge the pack at that rate, I need 16.8v, 60 Amp.
It doesn't have to be fast. Overnight is fine.
Also, I have spent about $50.00 so far - I don't want to spend $500 on a charger.
Any suggestions ?
Thanks !
