pneumatics while drain your battery way faster than normal skate wheels.
With urethane, you can easily coast, and you are restricted to pavement- all terrain wheels open up some more challenging environments, and take more power to start them up and keep them going.
it is simply that they (on average) have to pull more watts than street wheels!
Back when we sold the 5inch pneumatic wheels, I did a single motor range test with both the pneumatics and 83mm Enertion wheels on the same route (all street, some light hills), and had 70%+ left on the street setup when the pneumatics had under 40% at the same point.
If your belt is too tight it can cause excessive watt usage. Be sure you have a little slack in that belt. Rotate the wheel and check the belt through the whole rotation to be sure the belt does not get tight at any point. Don’t make the belt so loose that you end up skipping teeth constantly either.
thanks for the clarification. Maybe I’ll try swapping out the wheels with normal wheels and see if there is a difference. Hm so then what type of batteries would support the high drain and can give a decent amount of range for pneumatic wheels?
I guess a 12S and slick tires might help…??? Also LIPo batteries have more kick, that may help 2.
if you’re packin pneumies on there then you have plenty of room for a giant box filled with cells. i say stack on the watt hours.
How about this, 2 space cells stacked and connected in parallel!!!
thanks guys for the support. I think I might try the Lipo option as I find Lipo’s to be more efficient for high power consumption setup
2 space cells?! that’s ~$800 right there! 
also, I’m not sure if I want to deal with Enertion anymore due to the terrible wait and increasingly poor customer service. Last time I purchased a space cell, I waited for 3+ months…
i’m using Lipos. They are a good option if your wanting maximum power. And if you mount them in a easy access enclosure, you can bring extras in a backpack to go on long treks. I have a maximum 30 mile range with 3 packs. Although, I doubt my legs would hold up for that distance. I’m running 12s with dual motors and the power is amazing. You really have to brace yourself when you get on throttle.
No way, 3 months?? How long ago was that? Just ordered mine 3 weeks ago…
yup, 3 full months… this was back in mid Jan. when I made the order. Didn’t receive it until April.
yeah, I am going with Lipo as well for the pneumatics. I’ll most likely run it in 10S because I read somewhere that it’s not good for the VESC to be in 12S as it creates heating issues with the FETs and such. Plus, 10S on a sk3 192kv and 5in pneumatic wheels is fast enough haha
Holy sshh… So by the time I’d get mine, it’d be the end of the summer…
yea, sorry buddy. That is why I decided to make my own pack instead. But just need to figure out how to connect everything without blowing my apartment up lol
I’ll have to agree that running 12s is pushing everything to its limits. 10s is surely better for longevity. I almost went with 10s but found 6s lipos cheaper and more readily available than 5s lipos. So I went with 12s. 12s is ok with belt drive because with gear reduction You draw less amps. If your running any form of hub motors, then better to go 10s in my opinion.
The bigger the radius of the wheels, the greater the moment inertia. The greater the moment inertia, the harder it is to move, but once it starts moving, the harder it is to stop. Like rolling and stopping a boulder vs a marble. Takes a lot more more force or torque.
Didn’t see this thread back in my but keep your tires inflated pretty hard to reduce rolling resistance
This thread is pretty old, but I came across a similar issue, but on street wheels.
Here’s my thread about it: http://www.electric-skateboard.builders/t/space-cell-pro4-maximum-charge-stuck-at-94/10269/4
Don’t know what could’ve happened. I rarely take the battery/case off.
