Ordered 48 of these. High discharge cells are only 2500mah but with 4 in parallel I can hit peak discharge ability of 80 and these have a lot more stored energy at 3000mah
Maybe 28 mile range?
Going to pot them all in clear 70duro rubber stuck to the board with no bms and just the 12s series connections and those 4 in parallel. Will form small recessed holes in the rubber and it’s mold to reach each cell so I can monitor and balance. Very manual. Will use a couple to-be found 4 or 4.2 volt chargers and some light bulbs to discharge.
I don’t like my Icharger and am trying to sell it (to u?!) Any advice on thickness of bus bar or wiring necessary between the cells and paralleled packs? I plan to just solder the cell connections.
charge all in series on a bulk charger to 50v
If you’ve ever gotten 18650 do u bother testing or cycling them a coule times to cheek on them before u connect or did U just buy what u needed?
