6S Lipo 5A - single motor from enertion, bad hobby esc (waiting for the vesc) that is not really reliable when breaking so I’m rarely topping the speed (~18mph / 28kmh) of my build because I know that car and bikes can break much faster than me
Max range with these conditions is around 8 miles (13km) draining the battery from 25v to 21v (3.5v per cell), that is around 1h of continuous riding time at those low speeds ( compared to the other guys here ;), I think over 25mph will be scary for me because I know that here drivers don’t care much about pedestrians and bikes, they think the road is theirs, I think they care even less about skates ^^ )
First is commuting to an event, speed drops because I’m walking into the underwater tunnel, also they’re both door to door logs so the first and last part I’m walking, also I try to not go over 10mph when I’m on busy sidewalks, at least that should increase range
On the following one I stopped riding at some points at 3/4 of my ride and walked because traffic was too scary at rush hour in that area, can’t wait for my vesc to arrive
I’m ~95kg, I think this battery I’m using is very good, I got it for 60 usd, I’m waiting for another one to go 10A but it takes 1 month to arrive
I’ll try to make a 8 mile run and post the graph, that app I’m using graphs speed vs distance (graph on the bottom), do you have another app you suggest for android?
Thanks for the info
Wow that’s even more impressive for a big guy like me. I weight the same.
As for the graph I meant in general like the one lowGuido is doing for this thread but charting people’s speed vs distance ratios. To see if there is a sweet spot for efficency, just curious, you know for science (as LG would say)
Sorry to hear about your long wait, that’s the toughest part of this hobby
I’m waiting on quite a few things for my first build and it tortuous
My build looks a lot like yours. 6s 5000mah with a 190kv motor. I get around an hour of ride time. I weigh around 200 pounds/90 kg and ride on flat ground.
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
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
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:
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!
