Hey all!
This year, in my high school engineering class, my classmate wrote a grant and $1000 was donated to our class to build an electric longboard. It was fantastic! I emediatly fell in love. Dual drive, 12s, homemade deck- it was raw.
I’ve always wanted to build an E-skate since the boosted hype a few years back, and after building one for school, I put the nail in the coffin. I’ve been lurking for a while now, and have had some experience with the previous build for school. I’d love some input on my upcoming build!
Goals: *as lightweight as possible *7-8+ mile range (more the better) *great for carving *solid hill climbing ability *clean looking *easy to charge *smooth ride (Spokane streets kinda suck) *as cheap as possible (can splurge depending on how much lawn mowing is done this summer)
Parts list: (ITEMS WITH ! HAVE BEEN BOUGHT) *Deck- loaded tan tien flex 2 ! *caliber 2 50° 10inch ! *97mm flywheel clones ! *15mm belt, 15:36 ratio gearing (ebay) !
- torque VESC *torque 190kv 6374 sensored *torque motor mount *3x series turnigy 3s 5000mah {9 cell} (or 4x? 6000mah? I’m just worried about room, and the flex of the deck) *some bms for charging (bestech? They’re very expensive tho…) *anti spark xt90 loop key *printed enclosure (need to design- have printer) *mastercho mod gt2b *flat braided copper wire to mate enclosures
There she is! Super excited. Like I’ve mentioned within the parts list, I do have some questions and would like critique if possible.
Firstly, at a single 190kv, would 9s be a sufficient power supply? Or should I go 10 or 12? I would go 18650 cells, but they seem expensive and I don’t have a spot welder:/ Battery space is an issue as well(need to be close to trucks to prevent bottoming out) Has anyone else used the tan tien in a build? Haha am I the first? I could also top mount the drop through deck for more space…
Also, I should aim for the highest c rating output, correct? Higher amp output will reduce voltage sag, and improve range right?
What BMS should I get? Is there a cheaper option than bestech if I bypass it for discharging?
Sorry for the barrage of questions. Thanks everyone though! Excited for this build, and will keep this thread updated with the progression.
