I was chatting with a friend who also has a home-made EV about my pack issues. She also uses CALB batteries, but went with the CALB100AH (blue) instead of the CALB60AH. She’s in the process of parting out the EV, so I get her batteries.
This means I will rebuild the pack using CALB100AH – lower voltage but much better current. I now need to figure out how many I can fit into my existing space.
She had another suggestion: take the good CALB60AH and double it – turning two 60AH batteries into one 120AH battery. I’m going to play with that idea and see how well it all works out.
On the bad news front, CleanPower has sold their business, so I’m not sure if I can get more of the MiniBMS. I’ll just have to be careful with what I have for now.
