Hi guys, this is my first post on the forum. I’ve been doing some research on building my own eboard and was wondering if I could have some input on my build list. I have a lot of experience with quad and tricopter builds, so I’m pretty strong on the assembly side; I’m just not sure if I have the right parts chosen. Please give me any input you have. I made a notes column on the right with major questions I have; but feel free to tell me if theres a better part I should be looking at. I played varsity football all through HS so I’m a bigger dude (6’1", 260lbs), so should I be looking at a dual motor setup instead? My daily commute is mostly flat with only one small hill. I’m not trying to build some total speed demon. My main use will be commuting but it would be nice to hit 15 or 20 every once in a while.
I also currently have an Alva Pig. Any thoughts on using this, a shorter board, versus something like my ThreeSix Downhill, stability, strength, powerwise, etc?
Try to get the 192kv motor as they have more torque on lower speed and I also recommend getting VESC from Enertionboards.com / Ollinboardcompany.com as they are currently one of the best ESC you could get with nice low speed startup. Most ESC out there are not build to pull 60kg weight ++ for long period, hence you might wanna get something more decent for it’s purpose.
For the rest you could get opinion from other builders here
How would the battery life and performance compare between running 2 6s 8Ah lipos in series vs in parallel? I’m hoping to get at least 5-10 miles a charge. Is that going to be realistic with my motor/VESC combo?
If you have a VESC and you have the choice of running your batteries in parallel @6S or in series @12S, in my opinion it makes most sense to run them in series @12S because the current draw will be lower and so will heat losses. More efficient. 12S will give you a high top speed but the VESC will allow you to cap this to any speed you wish.
The 192kV motor would be ideal for 12S.
There’s a rule of thumb that says approx 1km range for every 10Wh, I confirmed this on my single motor setup, and going through some readings on the forum I’d say it looks pretty accurate.
Series: 12S 8ah = 44.V x 8 = 355Wh.
Parallel: 6S 16Ah = 22.2V x 16 = 355Wh
You should get way more than 15km. Probably more like 30km.
