Focbox has a good heatsink
today it pulled me 70amps for 30seconds and it only got to 80celsius
im 100kg or so with the board and i went like 5kmh on the hill
Here’s how I cool my focboxes. Air scoop, and fan to blow air past the aluminum heatsink. This allows the focboxes to be water tight in my enclosure and still get amazing cooling.
@GrecoMan that’s a heatsink for the 4.12 vesc correct? How come you have the bottom fets being cooled only? Also looks like your design doesn’t use direct fets, so there will be very little cooling compared to a vesc with direct Fets. Kinda reminds me of the heatsinks Chaka makes for his vesc’s.
in a dual config (unless you’re SPECIAL) just bottom fets is plenty. but yea, it’s just a simple mod to vescs. honesty, for me, the biggest perk is just having a dual vesc platform with everything securely mounted and all ports still open and accessible
This is my 95% Solution. I’m still trying to work on a way to make the whole thing water resistant but I don’t get much time to figure everything out at once. Dual Focbox with the CNC case from Kuglis. So far I haven’t upped my motor amps but to 70 each. However the only problem is I can’t find a hill steep enough to even get these motors above 55A Each. Plus this case keeps them super cool.
Im a big guy and if i run my board conservatively with 1 focbox i can reach the temperature limit going up some local hills. If i have the same board running dual i can ride as aggressively as i like up the same hills without ever even reaching 40 in a sealed enclosure.
Actually to keep things abit simpler, it doesn’t always have to be with a heatsink. if you run higher volts, it’s running cooler already. The best way to run cool is to avoid heat in the first place
