if you want more range then you could set it for cutoff at 36v and full charge at 50.4v assuming you have 12s li-ion

Can also limit your amps, you won’t be able to accelerate quite as fast but more likely to save some Wh that way also ideally let yourself neutral to slow down instead of being heavy on brakes and acceleration (if you could keep constant velocity and never stop that would be the most efficient i believe).
Also not sure if you mentioned it or not but pneumatics vs urethane matter and weight of rider plus riding conditions hard to guess without all the variables, metr helps a lot.
I’m trying to see if we can use raspi zero as alternative logger for uart data but going to take some doing to disable default usage on raspbian of the uart then some work to log and other stuff so maybe a ways out.

yes pneumatics wheels , evolve tiers 150 mm
You could try checking your tire pressure out too in that case, I pumped mine up from torqueboards after getting them and rolled a lot easier just kick pushing once they were pumped up, so imagine that equates to motor does less work if wheels are properly inflated (sure if you go too high the contact patch gets reduced some but if they can be squeezed with a lot of pressure by hand I would check them out). Think like mmaner said the limits could be lowered most likely without much issue either and some cells have more of their charge lower in the voltage range than others, for lipos I keep the limits high to keep the cells healthy and not risk them.

Can you set the vesc so that you get max torque from your motors but limit the topspeed? Thanks!
If you have max speed then you will automatically lose top speed.
I think i just mean if you can limit topspeed in the vesc with the same gearing but keep your current torque. Is that possible?
Now i go 45km/h but it is not needed. 38 or so would be enough but i would like to keep my startup torque.

I can use these on evolve trucks?
No, you’ll need to get evolve specific motor mounts. Torquboards used to carry them but they were overpriced (imo) and I don’t see them anymore. Dickyho has some, as well as a few other random esk8 vendors I can’t be bothered to look up right now.
Yeah there are a few out there, I want to be able to adjust the angle of my motors.
Gotcha. Only ones that are explicitly made for the evolve BCD and allow angle adjustment are from custom fabricators that don’t have them listed right now. Might hit one of them up or you could also just file out the holes on an evolve style mount for some slidey action.
If you limit the erpm you will effectively limit the top speed, so long as you don’t change the amperage you won’t change the torque.

What’s a good range for 10s2p if i also want the batteries to last and range isn’t an issus
If you have 10S 2P you have 20 cells if each cell is 2.5Ah you have 20 x 2.5 x 3.6V = 180Wh. With urethane wheels you can expect to get on avg 1km per 10Wh, so for the entire battery should expect about 18km or about 11 miles. With pneumatic wheels should expect about half the range, personally get better than average efficiency because I am light weight and very flat land around me in general.
I have no idea, I’m getting around 20 km from 12s8p on pneumatic tires,but I’m quite big and heavy and there is snow here so I’m spending about 30-35 wh/km
Is this safe?
Electrical tape
Planning to add more/neaten it up but want to make sure this isnt a cardinal sin.
You will get shit for not using kapton tape xD

Fair, I have to re-think it anyway as the extra height is too much for the enclosure 
These are the correct ones.
