As the title says, this would be my first build. Me and a friend, who has built a board, have quickly put together a list of the parts I plan on using. The main focuses of this board would be:
Decent range
Decent speed
An easily upgradeable platform for the future
Again, this is my first board so I’m probably making some mistakes as even my friend who helped me barely got his working. All I ask is that you help me. Thanks in advance.
Isnt it more econimical for you to order from www.alienpowersystem.com? They are based in UK and have similar motors to DIY in my opinion and a good reputation. They also have a lot of other esk8 stuff you might want to check them out if you have not already. Because if your package gets stopped by customs you will have to pay a lot, VAT+import fees.
It depents a bit on the amount of batteries you are going to put in series, but if you have 2 in series (22,2 V nominal) you would have a kind of low top speed with your 190 KV (rpm/v) motor. 22,2*190= 4200 rpm.
http://calc.esk8.it/ is a very useful site to see what your board will be capable of!
Didn’t realise that a 3s would be so bad for speed, I’d probably be better going for a 6 cell 18650 li ion then. Is there anyone on here that is UK based that could provide?
To be clear, higher voltage is more efficient…nit necessarily better for a vesc as there is less voltage delivery. Regardless if the “studies” I’ve been running a vesc in 6s for iber a year and it’s stood up at lease as well as my 10s boards. Though the lack of speed sucks .
IMO its better for the Vesc to run 9s compared to 6s… At 33v you Aren’t really pushing the voltage “limit”. As the standard Vesc’s only can take 27? Amps (Which is little) countinous. And with 6s you will (in theory) pull 50% more current,- compared to 9s.
Yea looks good except for the battery situation. Make sure to do your research with the BLDC online.
These videos will help when you come to that situation:
