Powell,
So far the Eplus performs well. No power cut offs. It rides smooth with surprising speed. A couple times, the throttle didn't respond on the first press but engaged on the second. It's always after slowing down and/or using the brakes. I assumed it was just a sofware delay since the throttle is suppose to stop when either brake is touched.

The battery shaped bar meter is full and the SOC is 100% after an overnight charged. It goes to empty after 5 or 6 miles (20 mph on the flat with moderate pedaling). The digital SOC on the display agrees. Still the bike will go at least another 5 miles under those conditions with the battery voltage holding above 33v. I wish I had an easy way to independently measure the remaining working capacity of the battery after all these years. If I switch the display to PWR, full throttle, the display shows 200 to 700 watts as you change the drive mode from 1 to 9.

So the electronics actually measures the amp hrs used and then calculates SOC% ?. Is there any way to read amp hrs instead of SOC%? Does the SOC calculation adjust for battery degradation due to age and number of charge cycles. I don't understand how it can show SOC = 0% and I can still go?
