Hi guys, this is my first build and my first post here. Please help to check my component selection and see if I am getting anything wrong or missing anything. Thank you
I am looking to build an electric mountain board mainly for street in bad condition (holes, bumps, rocks etc). Not going dual drive because of the price.
I calculated that I can reach ~35 km/hr (22 m/hr) top speed with a range of ~50 km (~31 m/hr)
which is more than what I want.
Currenty cost is around $900 USD including everything on this list and I would like to spend no more than this.
Wheels, trucks, motor mounts, drive pulley :
2x 200x50mm (8 Inch) front wheels
2x 200x50mm (8 Inch) with built in drive pulley HTD5 72T 15mm wide2x motor pulley HTD5 15T 15mm wide, 3mm key
2x HTD5 Belt 395mm, 15mm wide
2x Motor mount (50mm and 63mm motors)
1x front truck
1x rear truck for motor mount fitment

I’d recommend getting batteries with a higher discharge rating. Most 12s lipo build are done with 3x4s or 4x3s lipo packs, not 2x6s. Why? The former options will have a lower profile on your deck.
If you wanted a similar mAh, (as an example) you’d buy eight 3s packs: https://hobbyking.com/en_us/zippy-compact-5000mah-3s-25c-lipo-pack.html
The higher discharge rating, the better; I’m running 20C with 2x5s in series with no issues (riding on flats). Then again, if you’re gonna run 12s with 12Ah, that’s 532.8 Wh. That’s quite a lot!!! At that rate you might want to look into li-ion packs.
You can charge anything <=6s with a hobby lipo charger, like the iMax b6. Hope that helps, and good luck!
Regarding the batteries, how does two by two 5Ah 5S 20C lipo sound? they add up to 10Ah 10S 20C right?
I am okay with the range of 36.6km with this new battery set up
And is your recommendation about getting li-ion packs instead because of safety reasons?
Yup you’re exactly right… except it’ll be 5Ah 10S1P. Li-ion is a better battery technology (imo), more charge cycles and a better form factor for esk8.
I’m running lipo (as do many others) with no issues. but with your past setup, it was gonna be such a pain in a** to charge (with that many cells) that it makes more sense to get a BMS at the very least.
Not to mention you have to wait 3-4 weeks for delivery… @ATLesk8
My remotes come tested and pre-bound to the receiver. No tricky set up required,. You also get customer support and you support an eSk8 business that actually contributes to this community…
@JLabs maybe you should actually read the thread to the part where I solve the issue and it is the faulty vesc. I’m currently using 3 of these ebay remotes…ftw…hehe
Yup…they all work fine and bind on first try. I dont like that I have to change batteries or the overall design of the remote but they have seemingly been the most reliable for me so far vs the nano and benchwheel.
Hey don’t mean to hijack but can anyone tell me if I’ve got anything to worry about here (aside from the obvious. Clearance under deck, insane top speed etc) I’m running a single 190kv 6374 SK3, Torque VESC, 90mm wheels, 16:32 gears and I just ordered 2 6s 8000 mah lipos I’ll be running in series. I’m upgrading from 2 3s 5000mah lipos in series. Anything other than changing battery voltage cutoff start and end? Do I need to re-detect motor? Set any other parameters? Just wanna make sure I don’t damage my VESC or any other components. Thanks in advance anyone!!
