So I * plotted* the driven Distance With the Battery percentage. The ride was fairly even and quiet consistent in power consumption. I rode it until the battery was dead ( OneWheel V1) 15 km .

Then I plotted the Battery Voltage to the Battery Percentage (km of the ride / 15 km )

Then I figured out the **spline interpolation function** for the points given

Here the points x value = Voltage y Value = Battery percentage

[47,1], [47.9,4], [50.9,4],[51,8,18],[52.7,4],[52.8,43],[53,58],[53.1,68],[53.2,73],[53.62,85], [53.71,94],[58,100]

for Voltage 47 Volt- 53.75 Volts

**Battery Percentage = Voltage / (33.99221994 * Voltage - 507.8752687 Voltage(^1/2) + 1896.895271)**

for Voltage 53.75 - 58 Volts

**Battery percentage = 100 + (4.4-100)/(1+exp((Voltage-53)/0.42))**

I will make a little App for myself to **bypass the difficulties** of the Official OneWheel App.

Hope this proves * useful* to some of you out there...![alt text]

Here the graphs of the sigmoid and exponential function plotting voltage to Battery percentage

Cheers
