MakerX new product. High voltage ESC. Based on 75300.
Go-FOC HI300（based on 75300 hardware）
Voltage: 75V maximum (recommended within 16S)
Current: 300A continuous, maximum 400A
Go-FOC HV200(based on 100250 hardware）
Voltage: 100V maximum (recommended within 18S)
Current: 200A continuous, maximum 250A
That looks like a version of A200 vesc by triforce. I am so buying 2 of these.
Yeh，We have referred to the circuit layout of A200s, and the hardware is based on VESC75300.
Well It is opensource, looks great does it have an imu?
While it looks like you’ve done your homework on the tripple shunt design. Do you have any tangible proof of the 200A? I wouldn’t want to real world test if it can handle it or not…
A dyno test with video would really be helpful. 
So much better than the maytech 200 ESC without single shunt per phase design.
yeh.We will take a test video. It currently works well on an electric surfboard.
There is no integrated imu on the circuit board. But you can connect it externally
You have to offer those on https://efoil.builders/ too! If you can add water cooled heat sink and your esc turns out to be reliable, you have a winner!
If I didn’t just bought A200S, I would take your new esc for sure! I am so excited!
Interesting, that’s a 12 & 18FET design then. Looks nicely done on pics, and recognize inspiration from A200s!
Careful, did you test it at 16S to advertise so? If it is 75v absolute max, 15S advertising seems more reasonable I think.
Will the HFI100 also have a heatsink case like the 200 appears to have?

Big emphasis on the efoil application! A real competitive 75/300 alternative would be adopted like crazy over there.
Yeh,there will be a heat sink
It’s probably much better considering 13s is basically touching the nono 60v zone that the zesc has 
if you make a suitable heatsink for this that allows it to be mounted in an enclosure in a water resistant maner then im deffo on board with these. If you get the heatsink right im going to buy a pair of the 100A ones
7-8 layers of conformal coating (419D) to waterproof it and drop a heatsink with tall ass fins through your enclosure so you can mount any esc on it using a thin thermal pad and foam.
HI100 does not come with a case/mounting bracket of any type?
Hey,The heat sink of HI100 is still being processed. It may take another week to send out.
I’ve been using the team triforce a200s for months now on an ebike. Its nice having the voltage headroom and no drv to blow.
@YUTW123 On your HI200, how come you don’t install the screw terminals for the phase wire when your pcb has the holes?
