@Glyph @causticgrip The onewheel doesn't have normal brakes, so it has to use regenerative braking. When it does that, it has to store the power somewhere. If it doesn't it could overheat. This means you either just have to not be at 100% when going down a hill, or your board overheats and shuts off anyway. Either way the board would shutoff eventually.
The difference between the charger and regenerative braking is the charger just stops producing power. Whereas the regenerative braking continues to generate power because the rider decides to keep going down a hill.
