i just put a whole bunch of reduction into an old single drive board i have. 14:40 on 213kv and that b*tch wants to climb walls now. Not sure how the range will be affected. prob worse maybe not

Lol… You can put in drywall screws with that lol
How is it skating around those areas of london? Will be building a board soon and going around those parts. Have you had any issues going in the cycle highways?
Some angry bike riders on bike lanes sometimes but no majour issues, be careful of cars popping out from intersections, they don’t know that you can’t brake as fast as a bike.
on park paths and in general when riding on sidewalks and in smaller roads there are a lot of cracks and rough asphalt/terrain, because of that I switched recently to bigger wheels and it’s slightly better now
I haven’t made any scientific measurement but I’d say around an hour with a 6S 5200mah, single motor setup A few small hills but I only weight about 60kg
6S 5000mAh with 4.1V to 3.76V: 11.53KM in 43min. Did not try to go full speed but was taking it slow and just cruised around town on bicycle lanes.
Motor is a SK3 149kv with 20/28 9mm pulleys
Edit: charger says 3000mAh have been used

I have 2x3s in series for a 6s and just went close to 11.5 miles with 10.9v left. This was in about an hour and a half. I’m amazed at the performance of these lipos and the board as a whole. Just completed it a few days ago.
Tested the range of my board at a friend’s house this past weekend. He has a nice loop around the neighbourhood! I’m running a 6s 5000mAh setup. Got these results before soft voltage cutoff on VESC:
- Distance: 12.6 km
- Elapsed time: 0:39 (minutes)
- Max speed: 28.8 km/h
- Average speed: 18.65 km/h
the physicist in me is weeping 
firstly, riding time is a function of battery size, so you would usually swap axes really. and while time is already a nearly pointless measure, mAh is truly pointless. next time please use Wh! no offense meant, I would love statistics about drive train & battery efficiencies, i.e. max range as function of Wh. even that is flawed due to different riding speeds, but everyone can try to be as efficient as possible, i.e. run quite slowly, on flat terrain without much braking & accelerating.
on endless sphere we also had a graph of power consumption as function of velocity - that has been really useful for me to determine what kind of battery current Ill have to expect. so please, more threads like these, but think about the relevant quantities beforehand! 
Can you provide a link?
hi @whitepony how do i calculate the watt hours? sometimes it seemed like: volt x amp hours = watt hours but then a normal enertion space cell would have 360 and not the advertised 270
yea, volt x amp hours is correct. space cell was using 2500mAh cells from what I remember - in a 10S3P config it has 7.5Ah and thats 36x7.5 = 270Wh -> as advertised!

ah thanks for the clarification where my mistake was
The whole reason i did this was because everyone told me its “pointless” and “wrong” And because watt hours and range is common dog fuck. I like to do things different. And I learn quite a lot doing it.

common dog fuck maybe, but can you link a graph with range as function of Wh? I havent seen one and it would be great to have, especially with the large enertion forum memberbase. there could be actually some halfway meaningful statistics! would be particularly interesting to compare efficiency of vesc vs other escs, single motor vs dual motor vs hub motor setups. I can tell you are offended, I would be too - but doing things different for the sake of doing it different isnt the best motivation in my eyes. 
Is there some sort of online charting tool where we can add our stats and it will add them to a graph that is then dynamically linked in this thread? So that every change will automatically update the graph in the top post? That would be nice and really helpful for determining the size of your next battery pack.

The only thing that offends me is when you call this forum enertion.
