I’m planning my first build and would love some constructive criticism. My goal is to be able to hit ~30mph, >25 mile range, and have a board with an authoritative, responsive feel - plenty of torque. I may want to keep the door open for AT riding, but I’m mostly interested in cruising around town and commuting. Let me know what you think. Thanks!
Long Board Setup
Dual TB 6374 on TB 218mm trucks (single kingpin)
14T/40T pulleys
TB 110 74A wheels (streets and sidewalks around here can be kind of chunky)
I think if you’re gonna entertain the idea of a larger pack, you’ll need to choose the deck and enclosure before you iron out any of the other details (except ESCs, BMSs… The small stuff doesn’t matter toooo much)
Like my enclosure / deck only fits 4p 18650 and 3p 21700. I should have really thought about it before I committed because I’m honestly fairly unsatisfied with the range. Just kept pushing ahead and now I’m $2500+ into the project.
With single drive that battery would be enough for the range. But dual drive feels way better, so yeah, either get a bigger battery, or more efficient drive train (gears or direct drive)
Since it was a TB pack I was assuming it’s 30q. They’re good, don’t let me try and tell you otherwise, but they aren’t a peak performance cell.
I’m assuming you won’t be drawing the 180a+ that 6p 30t would provide, so the 30q would make more sense since they both have the same capacity as they’re cheaper and smaller
Read this, do this. Don’t make mistakes others have made countless times before you
My other advice — after you’ve went through steps 1 through 4 — is that with those wheels you should run a 15:44 ratio at 190Kv or less. Maybe 170Kv to 200Kv, assuming 12S li-ion voltages. Don’t use a wheel pulley smaller than 44T if responsive is your goal. This is a really good option, depending of course on the truck hangers you plan to use.
