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!

5

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. 7461147 Würth Elektronik | Connectors, Interconnects | DigiKey

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:

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 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:
