Hi. So I switched the bike to 72V and there is a ton of power. I understand why the throttle is set to soft start 5 now (1-10 and soft and hard). I havent really opened it up yet to see what it can do but I went on a 10 mile errand ride that I typically take with my 500W rear hub and recorded it. Since I dont have a watt meter with the 72V setup it was difficult to do a direct comparison. On the 500W, I averaged like 2 miles per 1 aH. Here on the 72V Cyclone, I think going to the store (5mi) I used about 3V drop in resting voltage and coming back it was only like 2V drop, which is 1.5V and 1V respectively on my 36V 500W ebike. I think that is pretty decent. For the efficiency test, I pedal about the same as I would on my 500W.

Also, during this ride, I understand the limits of the scooter batteries. There is significant voltage sag when I really want speed +30 mph. Gonna muck around with it a bit more and clean it well then start gathering and brainstorming about phase 3 (gas generator). I am not going to do phase 2 (more batteries and aerodynamics) right away as I need to make sure my battery configuration matches what I have so the batteries dont blow up when I parallel charge all of them. But, the gas generator is key to this build. At the moment, if I get about 2-2.5 mile per V that is about 30-40 mile range (discounting some) from full charge 84V to 66V (not gonna hit that). I want more than that.

Here is the video. I am still learning but I fixed the awful static noise. Music is on and off. I will fix camera angle in next ride. :ROFLMAO:

Last video for a bit. Just wanted to post the ride back from store if anyone is interested. Cleaned bike and changed the white zip ties to black today. I will start the phase 3 work soon. Here I am coming home (5 mi) and dropped 2V. Much better than ride to store (2.5-3V).
