Good afternoon everyone.
I've run into a bit of a problem in designing my DIY electric motorcycle. Turns out the CBR125 isn't the best frame to hold a single large format battery so it seems I have to go with two smaller batteries.
I've decided to go with pre made 18650 batteries and I want to have a 96v (26s 109.2v) system with 40-50Ah and it seems the best way to hit those numbers is to buy two packs and run a 2s configuration.
(I know 4-5kw is not much capacity for an electric motorcycle but I'll have two and make the packs removable)
The only thing I don't know about is how the BMS's will handle the configuration.
I'm not overly worried about discharging as both BMS would be rated for 120A and the max i would be pulling continuous would be 100A, so it seems like it would work fine, but I don't know if charging will be an issue. Ideally I'd like to just use one single charge port but I'm not sure if connecting 2 different BMS in a 2s configuration will work or if it would just confuse the BMS and end up not charging at all.
Is this possible or would I be better off biting the bullet and getting a custom (read as "expensive") battery made up for my specific application.
Thanks in advance
