So I had a chance to get some riding in yesterday and was able to optimize some of my VESC settings for the Carvon Single Hub V2 motor + Enertion Space Cell with the help of @chaka and @onloop. I can’t conduct range tests at the moment because the weather is too cold but speed is easy.
First I used recommended VESC settings for the Space Cell:
Motor Max: 80.00 Motor Min: -60.00 Bat Max: 30.00 Batt Min (Regen): -12.00 Absolute Max: 130.00
1st ride had FOC enabled and while it was a super smooth and a quiet ride, my top speed seemed to be capped at around 18mph which felt safe, but slow. The stealth of the Carvon hub is pretty sweet. Along with a 29" deck size and FOC, I attracted very little attention. At the moment FOC feels like incognito mode. There are times, especially traveling through the city, when I won’t go past 18mph and I want to attract as little attention as possible.
2nd ride I had BLDC enabled, much noisier, but performance is beefier. I hit a top speed of 27mph before I got the speed wobble and chickened out. Pretty sure I could have gone 30mph+. Also noticed the VESC would back off after hitting the brake at max speed which is a little scary with the coasting ability of the hub motor. I definitely attracted more attention with this setting. However, the Carvon hub noise compared to the E-GO belt drive noise is way less obnoxious and kind of a pleasant whirring.
3rd ride I had BLDC enabled but changed the Space Cell settings to:
Motor Max: 50.00 Motor Min: -30.00 Bat Max: 30.00 Batt Min (Regen): -12.00 Absolute Max: 130.00
Hit a top speed of 21mph, definitely could have gone faster but was being conservative. Brakes seemed to be more responsive and didn’t notice any cut outs. I believe this setting is probably the best all purpose setting for the Carvon V2 Single Hub + Space Cell + VESC.
I’d love to compare settings with anyone else using this combo but I’m definitely satisfied that I can hit 27mph+ on a single hub.
