Hey everyone!
I am currently working on a conversion and spotted these packs for sale on eBay. Now I know the dollar per kilowatt isn't that great on these, but I am trying to keep the costs low, so I plan to start out with a few of these for a proof of concept and then upgrade down the road.
My question is, how would I go about charging these? They're an odd voltage, 40v, most chargers for lithium batteries are 36 or 48. I don't want to undercharge or overcharge, as I know that is a huge risk with lithium, so what's the best method to proceed? I plan to get 3 or 4 of the modules, I just want to understand what the process is to get them charged up.
