Thank you Monstarr
Have to still fabricate some bus-bars and parallel the cells...
btw, what do you think? I guess paralleling those cells balance wires should be enough I guess?
Or should I go with something thicker gauge?
I don't just need to parallel the packs. O also need to parallel the cells within. If you wonder what I mean.
I have four pack a 10s2p. I need to reconfigure them to achieve 20s4p.
Sorry for late reply. Been somewhat of a pretty hectic period the last weeks for me.
But yeah looking good! They seem like a great fit for your frame.
What I know about paralleling packs is that each series combination (so 20s2p in this case) should need their own BMS device which can shut it off. Thats the way it is also done in large storage batteries etc. Making designing the protection electronics side a bit tricky with off the shelf 'dumb' BMS systems.
I don't really have a lot of experience with the way you are paralleling them. So cant give any advice about it. But if you manage to physical parallel them while still being mounted in the double 20s2P config then kudos for you!
