Hoping someone might be able to chime in on what Ninebot/Segway uses for the BMS.
I have a es1 with the dual battery setup however I would like to add extra power for range.
via craigslist i bought two broken es1 and the battery packs look fine, voltage was putting out 35 on both packs however the 4pin which i thought was balancing leads dont put out anything on the multi-meter. Off the top of my head I was thinking just pop them in parallel and somehow disable regen but... since I dont know the BMS or how to tap into it i held off.
open to ideas =)
