OK, now this is getting seriously fun !
Third test today on flat terrain with these modified settings: Batt max: 30A Battery cutoff start: 39,6V Battery cutoff end: 38,4V Max ERPM: 40000
Stats: Distance: 21,38km Avg speed: 20,35kph Top speed: 37,5kph Charge used: 4850mAh
No more cut-offs when accelerating. No nunchuck dropouts either. Me happy
I tried hitting 40kph but got speed wobble because I had my trucks way too loose so I backed off. I’m pretty sure that within a few rides 40kph will not feel fast at all.
Towards the end of my ride the VESC unexpectedly cut off the power twice but my wattmeter was still showing 44V by the time I turned the board over to look. The wattmeter was also reading a peak power of 4125W, which is impossible. I think it can’t cope well with the regenerative braking. It may fail soon. I was probably hitting the lower cutoff voltage so I kept off the stick and rode the last few hundred meters at snail pace. Because you know, pushing sucks
So, the batteries ain’t as bad as I first thought. I’d say acceptable for the price. Anyways, my Zippy’s arrived today so if the weather keeps up I’ll give those a try later this week to see how they compare.
I hit a few rough patches with some loose gravel, the Flywheels just ate that gravel up. The R-SPEC’s on the other hand, got pummeled: But hey, a good tool wears signs of use well
I removed the unused motor though. No use dragging it around for nothing. I hope my VESCs from @chaka come soon, dual drive will be insane.
I also started an offensive against rattle. I found one of these dampening mats at the local hardware store and put some in my control box, to prevent wires rattling. I also added some thin dampening material to keep the wattmeter from rattling against the lid:
