I just bought a used chinese board (paean H2B) for a really good price. I don’t like the esc that it has in it (feels too binary and unresponsive). Honestly, I just don’t feel safe on it. I also have a wowgo 2s which has a much better esc (hobbywing right?). From what I’ve read, this esc is pretty hard to get and is only for hub motors. Any suggestions on a cheap-ish esc that will work with a belt drive?
Motors: 2x 900w motors Battery: Samsung 10c.2p 42v
There was a recent sale for Flipsky Dual 4.20plus
Do you have a link to it?
Or you can grab the plus version
That’s a tad out of my budget unfortunately. Would an esc designed for hub motors (like the wowgo one) work with this belt drive system?
There is a belt version one it’s actually called a, esc substitute, but remember buy cheap buy twice, the esc substitute’s have a tendency for half of the esc to die
Get 2 of these you won’t be disappointed
That looks like more of my price range. How would I hook up the remote with this setup? Is there a wiring diagram somewhere for doing two of these?
(nevermind, found it here: https://www.electric-skateboard.builders/t/what-is-the-correct-esc-amp-calculation/38078)Also how do I pick the right amp rating for the esc? I would assume that it depends on my battery and the motors but I’m not sure how to do the calculation 
You’ll have to get two of them.
And you can run them in CAN BUS, or SPLIT PPM
And you could get a mini remote for 15$ off of AliExpress
You don’t, it’s a VESC it’s fully configurable
Right but it seems like they’re rated for how many amps it can put out (in the hardware). ex: that aliexpress one is 50A. I looked around on the forum and read this: What is the correct ESC Amp calculation? - #3 by lowGuido - ESK8 Electronics - Electric Skateboard Builders Forum | Learn How to Build your own E-board but I’m still a bit confused. I understand that I can limit the power draw with a vesc but I want to make sure that I get the full performance from my board and not bottleneck it in the esc.
For the remote, can I use any 2.4 ghz remote? Would the one from the hobbywing esc (wowgo 2s) work?
No you need a remote that includes a receiver.
Do I connect the two in series or parallel to the battery?
Parallel
10char
What about the fuse/switch? The board that I have just has a push button switch with 4 wires coming out (2 for led, 2 for button?).
I also have a battery indicator light thing. Would that be able to plug into the the vesc to show remaining battery?
Your best, cheapest and most reliable option is a loopkey. Basically an XT90-S connector on the positive wire between the battery and ESC, with the mating plug bridged with a wire. To turn stuff on, plug in the key (connector). To turn stuff off, unplug it. Rock simple.
For that you would need to use a anti spark switch or Loop key and install the battery indicator after whichever one you choose.
You obviously are trying to build this on a shoestring budget, so don’t even bother with an electronic antispark. They’re expensive and they break.
For an indicator, you can get either a digital voltmeter module that just tells you the voltage, or you can get an actual battery meter module that does the math and tells you a %. Either is available from Amazon, ebay, or many of the esk8 hardware sellers.
