24/36V ESC Substitute for Noob Build

ESK8 Electronics
1

Hi All,

Short term lurker here! Post number one, could not find more specifics around this product using the search function. Turning my longboard into an Esk8 on a bit of a budget. This particular component looks ok for my needs:

  • Max Speed: 20MPH
  • Range: 10 Miles
  • Rider Weight: 180 pounds
  • Terrain: smooth concrete/brick with slight hills
  • Occasional weekend rider
  • Single Motor Belt Driven

My primary question is around the max amp rating of the ESC. On-site specs indicate between 10 and 15 amps max typically. However if I go 6s this limits me in theory to 350w motorā€¦ (350w/24v) Surely this is not the case? Does anyone have experience using these? What have I missed?

Examples of similar product:

Thanks in advance.

With a lower voltage battery a low current rating will limit the max power.

With a 10 amp limit at 24 volts you wont even break 250 watts.

High current at low voltage also chews through battery capacity in a hurry. Go for as high a voltage as you can.

Thank you for the quick response. Even at 36 volts (limit with this esc) I will not achieve my target of 20MPH I forgot to mention that planned build incorporates motor mount/belt drive.

I read a previous reply where someone suggested using RC Car/Truck ESC from 1/8 or 1/5 scale units. Possibly like the below? I will spend some more time reading up on the ESC forum.

A VESC is not really a huge splurge in the grand scheme of things.

The ESC is the heart of an electric skateboard and being able to configure it to your riding style makes for a way better experience.

Agreed, reading through so many posts working from my own limited experience it seems this is a component I donā€™t working out of budget for. I will read up a bit more later this evening, for now a quick search returns this unit which would allow for 1800w motor running a 36v system.

I am aware this is not a VESC:) Any suggestions would be welcome, I have a Flipsky FS-GT2 remote

That is a VESC.

VESC is a trademarked name so companies that make clones have to say they are compatible but cannot call there device a VESC.

36v can definitely get you past 20mph.

I have a 36v board that is geared to 26mph on 5065 200kv racerstars.

I have one of those ā€œesc substitutesā€ that I never used, if you want something cheap and fast. These are good for budget builds since it includes the remote and power switch, things youā€™ll have to buy with any vesc based esc. Pretty much every prebuilt board runs this esc, and setup is plug and play, no vesctool setup headaches. PM if youā€™re interested

I have no doubt that 36v can get you past 20mph but seems theoretically unlikely if you canā€™t exceed a 14amp draw. (ESC Substitute)

I guess what Iā€™m wanting to hear is someone say, ā€˜I run a 1500w motor on a 36v system on my esc substitute all day long and no issuesā€™. And then include a link:)

Thanks again guys.

I dont know where it was, but looking for info came accross a guys post that did some tests. He changed a certain resistor with a higher value. And replaced the caps for 100v types. And did some tests with different batteries. I think he even tried 16sā€¦ the board beeped like mad but still it worked making the 36v rated hubs spin like mad. But that being said he didnt test the board under load.
