How do you manage to get only 40 km on a 12s7p? Are the pneumatics killing the range? That wh/km is massive
- I never run my board down completely
- Where I live, it is very hilly and hills kill range.

I have been getting around 15 miles on 12s4p 30Q (~520Wh) so 30 Wh/mile.
If your getting 40K then that is ~25 miles on 12s7p 30Q (~920Wh) so about 35 Wh/mile.
Seems about right considering im running quite a high Tyre pressure on street treads.

I am running 30psi max and ride rather aggressively. The consumption as you also said is consistent with my other board that has a 12s5p , 6374 motors and 6in tarmac tyres that I run at 50psi.

I was working on my first diy- Going with trampa holybro, vertigo trucks, hypa wheels with 7in inline tires, alien power system 6374 170kv motors. Was still sourcing the rest of the parts, was thinking trampa vesc6+ and a 12s6p 18650 30q pack.
BUT while searching for parts I obtained a trampa emtb and it is pretty sick! Has 80mm alien power system motors and helical gears instead of belts. I ordered a couple new lipos(for now) that they recommend for the board/monster box. I went through and cleaned up a few bad wires and re routed over the top of the binding like suggested by trampa, got a couple cable clamps to get still but still going to learn about the vesc tool a bit and update and get riding in the next week!

So got the 4 lipos in to try the board out, mainly to see if I wanted to dump 4-800 in a battery hahaha. Just did a test run and it was good! Going to put the dampeners back in and double check everything is tight and give it another go. Tried taking it up to some speed and it had some bad shakes around 20mph then had two springs pop loose. So that was the test ride leaving it how it came. If the blue are to stiff I have a set of yellows to try 
So far though I’m thinking that a proper battery pack will be in order for this board!

So this thing is a blast! Going to try adjusting the throttle curve a little bit, and have been playing with different dampeners and it’s riding pretty good! Yellow up front, blue in the rear.

Yes, I ride them for a long time now to get back with 9".
And did I have to talk about those Primo Stricker? On the board since I have buy it as a second hand … I guess more than 5 yrs of use, without a flat and still riding them on the last setup 
I mean, still the same set of tires !
