Well, this sort of works but not as I expected. I set it to auto and "voltage" and it captures a fairly accurate initial SOC but then varies in real time up and down as the motor current causes the voltage to dip under power, then rebound as you coast. The way I had envisioned this to work would be that with the watt hours and voltage set and saved in the display, then when you pop on the battery in an intermediate SOC the system would estimate remaining WH % and then reduce by WH usage until depleted. So voltage would only be used to establish the initial SOC, not to keep running the SOC calc in real time since voltage is never stable while underway. My CYC bikes operate as I describe so I am not sure why we can't do this in OSF? Perhaps there is some reason I am not aware of?
