Hey guys. I have seen these battery parallel boxes at most ebike shops around here.
They claim to be able to run batteries in parallel with differing capacities. You can also set it up to auto switch to a different battery when one runs flat instead of parallel.
How does a splitter even out the difference in capacity and cells with a parallel setup?
Are these legit? I have a 36v 630wh narrow silverfish battery, and recently purchased a 720wh 36v pack for the top tube and would love to be able to run them in parallel. But I wouldn't normally trust two packs with different capacities and different cells to pair well in parallel.
I'm getting about 90-110km range running throttle at max off the 630wh battery on rough rail trails. It would be good to have two batteries in parallel to limit the voltage drop as well as get better range. Should get over 200km easy.
Had a mate run two different capacity batteries on his scooter and one kept trying to charge the other and the BMS would shut down and go into charge mode as soon as the batteries were unbalanced. Would this just run like a second BMS which balances both cells?
