I am planning to build my first electric skateboard. I am no experts when it comes building Eboards so I would like some advice on the parts I chose for this build.
I’m looking for a max speed of 25 - 30 km/h and a 10+ km range. My budget is around $300,-.
Your deck and motor link do not work
For cheap wheels, there’s the fake ABEC wheels, for very cheap on ebay or aliexpress, in 83mm or 90mm (maybe bigger too)
300 dollars is a little too tight of a budget… Esk8 is an expensive hobby
You could do it for 300 dollars, but excluding the battery
An you said you want to do it yourself ? You know how to ? What configuration are you aiming at ?
cheers
Dual 6355 motors would have more torque on startup, but a single 6374 is already very good. You DON’T have the budget for dual motors
(The motor you chose is fine (according to other people on this forum), but 200KV will probably be too fast for you. Use http://calc.esk8.it/ or https://calc.3dservisas.eu/ to put in the values of your components to see final top speed and such.)
Where in the EU are you from? If you were in the UK you could get Caguama wheels from https://skatehut.co.uk (But they have a Kegel core, so you’d need a different pulley kit / just a different wheel pulley.)
Btw, although your ESC will probably work, it might break easily / not be able to drive your motor to its full potential. I recommend buying a second-hand VESC from someone on the forum.
I haven’t personally tried single motor yet (in a few months I will), but people say that the difference between dual 6355 and single 6374 isn’t that big. (Also your budget is SUPER small, dual motors means 2x the price for mounts, motors and ESC, possibly battery if you want to make it even worth it.) Don’t go dual motors for a budget build
For the VESC I recommend getting a used Maytech or Torqueboards vesc from someone on the forum. Those seem to have a good reputation. (Although for your budget you might need to go with something even cheaper. Dhiko has an ESC on his ebay shop, I don’t know much about it though.)
turnigy on hobbyking is good, graphene are the best but more expensive
you’ll need a balance charger too then if you’re going for lipos
but lipos are easier to work with
That single esc will not provide enough braking power to stop you. Spend a little more and buy a dual esc ($60) and dual motor. If you still want single drive go with a flipsky 4.12 vesc ($60) and 63mm motor. Flipsky vesc is not the best vesc but it’s in your price range.
Flipsky 4.12 vesc $60,
Dickyho mount and gear $40,
Flywheel clone 90mm wheels $40?
Battery $120?
Deck $50?
Enclosure $60,
Wires and hardwares $50,
Motor $80.
Trucks $50,
mini rc Remote/ receiver $20
this is correct, you can ditch the bms part and the plug to charge the battery if you want a really simple design, and get a balance charger (most of them goes up to 6s, and are cheap, look for imax b6 or imax b6ac if you don’t hav a power generator)
The bms is the circuit directly plug in the battery, it’s for battery management system, it makes sure the battery are getting charges and discharge while still balanced
About the bms, you have 2 configurations : charge and discharge (the “normal” one) and only discharge
This last one is the most use here because it’s more reliable : when riding, all the amp are going through the bms, so you need it to be rated over you estimated max discharge, but even then then still tend to break often-ish
Having it charge only is safer for the board, because the current is flowing through it only when it’s charging, the discharge is bypassed and goes directly to the esc
So either you go with a big and powerful bms for charge and discharge (so more expensive)
or a small and cheap one for charge only (10A/15A is enough)
Go check the wiring schematic, I find them quite confusing at first, how to wire everything together and else
Also, you need an antispark : with voltage that high, it creates spark when plugging everything, which is very bad for the electronics. So you can have an antispark like the one on the picture
But cheaper and way safer (the electronic ones tend to break quite often) is using a XT90S, that you plug and unplug. Okay it makes the look less clean, but it’s less of a hussle
