Looks promising ! Can you share some details like motor cable gauge size / material ? I already see the battery are 2x12AWG cables. Does it have built in Bluetooth as well ? What about power switch feature ? Can you share a video where you push the stated 200A continuous on it while measuring the temperature ?

Thanks!

Did someone buy a bunch of power boards from team triforce? They look identical

Great design but why VESC people solder wires that way! so ugly and useless! just add couple of more $$ in to the BOM and use thru hole bolt connectors. for both battery side and motor side!

Did you have an IMU on there? Just curious for another project that could use some higher voltage :smiley:

It actually looks like it has solder pads for Wurth M4 studs. https://www.digikey.com/products/en?keywords=7461147

It does have those pads. Power board and form factor look almost identical to this: http://teamtriforceuk.com/a200s-v2-1-last-units-no-heatsink/

Apparently, this board family is now mass produced and available on Taobao for a lesser price. The 75V100A cost 1200CNY ie 170usd so not much cheaper than MakerX (195usd) :thinking:

Yeah I saw that. There’s a big thread on the Esk8 forums about it. Not sure why Samisin thinks its a different product. They are all based off the A200s design. It’s just been mass produced in China now.

Looks like just the heatsync in 120CNY. Whole thing 1208CNY. ~$170 .

The same yong shop offers a 100A anti spark switch for 35usd:

@brycej: corrected :wink:

Does anyone have a picture of the power board layout?

If its the same as the A200S then it will look like this: https://cdn11.bigcommerce.com/s-4t55i5fv4j/images/stencil/1280x1280/products/134/478/bottom__81380.1567537607.1280.1280__67404.1581940699.jpg?c=2&imbypass=on

it seems it is a spin off of a200s I am using but this is definitely slightly different design

Maker-X offers the HI200 75200 for 275usd.
Flipsky has just started selling the same product called FSESC75200 for 325usd:

  • Voltage:14-75V( safe for 3-16S)
  • Continuous Current : 200A
  • Max Current :300A
  • Size:100mmx61mmx30mm

Or here without heatsink for $232: https://www.aliexpress.com/item/4001145862701.html?spm=a2g0o.productlist.0.0.109f7b53u1vyON&algo_pvid=26f59b00-0f26-4f5b-8490-deb91107687b&algo_expid=26f59b00-0f26-4f5b-8490-deb91107687b-1&btsid=0b0a050115935030228752339e4fe3&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_

It seems the ESC is made by a company name Yonggang.

From the same seller - FU TIAN Store - both items mounted for 260usd (instead of 265/295 or 325 usd), best price (so far) on the market. Don’t know about the customer support though:
