E-scooter milage test

Epilogue
It's been almost a year and three months since I bought Ninebot ES1 scooter. The odometer shows 2200 km.
The scooter is slightly scratched in some places, but is still a rugged machine. I think it's time to see how far can it go on a single charge and to find out its battery capacity.

Preparation
I could not find a single long stretch of time for proper evaluation, because it would take 2 to 3 hours straight. Moreover, the track has to be leveled and precalculated to avoid unexpected depletion of the battery and to avoid riding the thing by kicking foot (it's hard). So I decided that it is best to just commute like normal and keep an eye on the odometer.
I charged the scooter overnight to 100%.

Measuring
Yesterday's commute to work was 13.51 km, back home - 13.54 km. Both ways the scooter was set to the "S" (Standard) mode. When I got home the battery still had 38% of the juice left.
Today I took another way to work and it totaled at 12.39 km in the "E" (Eco) mode. Why eco? I couldn't be sure of the milage and took it as a precaution. Besides, I think the official measurings are all done in this mode.

Conclusion
The sum of all three commutes is 39.44 km. 12% left.
Let's account for the advertised 45 km on a single charge: (39.44+12%)/45*100 = 98.16%.
I think it's a great result.
