max charge 64v
14s 54~56v , bottom 3.4v top 4v (then Ican still use my regular48v 500ah solar battery bank )
16s 64v , bottom 3v top 4v
(can not use any other battery bank here unless I cheat with a DC-DC step up buck converter)
I am just trying to decide how I should make a bank that will be made from scrap 18650 cells with capacities under 1000Mahwithout using balancers (I will still fuse every cell)
I was thinking of just making small packs of either 14~16s 1p cells or 28~32s 2p cells then just parallelthem all on the main bus bar (makes it easier for me to find matching sets)
I have been finding it hard getting 18650 cells as just about every laptop that passes through the store lately are not 18650
currently I have70KwH worth of solar power going to waste (offgrid) and use 120KwH daily
and need to have more storage while18560 cell qtytrickling in
6 years and only 1/4 of my goal
I will not pay more than 50 cents per 1000mah , I normally buy 12v batteries for $50 / 100ah
