Never brake at full battery charge, just under 95%.
E-scooters in general as the max doesn't handle KERS while braking with a battery state above 95%. When you try to brake neverthanless, you're overcharging the battery over 100% which causes severe components damage.
Always set KERS to low or off for that case. Never or just slightly brake and freewheel at the beginning of your ride, this ensures, that you still will have fun with your max!
