Its brand new scooter, from local store, stock oem, had no hardware or firmware modificatioms before me.
Was: bms v115; ble v81; drv v151; prod: nov 2018
Modfied to: bms v107; drv v138, tested few modifications, now it runs on: kers 40, max speed 45, eco 19, start speed 3, power const. 33000, remove limiter of35 pached, and remove charging pached.
runs good, but has limiter on 31 kmh anyway. feels like power inough for much higher speed, but motor shuts down or brakes downhill on 31 kmh
maybe my mistake, that i flashed modified v138 on 151 directly? ble version can have affect? WHATS WRONG??
yes, have made external battery, does not feel torque difference, but ofcourse less voltage drop on high currents, anyway it does not solve limiter problem. BMS measures less currents, im sure its not of battery overload
What firmware and max speed are you running?
Searching for Ninebot BMS (or cheap battery).
