So this thing is nice.
I've put 70+ km in like a week or so.
Custom firmware is a must though. SHFW is good, as I can set current or speed based throttle control.
I've settled on 22A and 15A.
22A is snappy, but kills battery fast, and 15A is slow 15-20 km/h ride, but calm and "it is good weather outside no need to hurry" types of ride.
Ninebot ES2 is a weird thing. At first glance chink didn't know what the fuck they are doing as it rides like shit, but if you start checking every park of the scooter without considering whole picture, it is pretty good engineering.
Battery - has smart BMS (no comparator bullshit, balances battery all the time with small current). BMS can report battery cell voltage, current, temperature.
Controller - FOC control. Regen current is <2A which doesn't kill battery (but is kinda pointless as most of energy is dissipated on controller and windings)
This makes me wonder, what did they change in E22 and E25 models.
