I wired up an HK 90a Boat ESC tonight to see if I could burn it up. Ran surprisingly well. I put about 3 miles on it. Nothing too strenuous, a few hills, but mostly flats at a about 15mph. I stopped every once in a while to check if it was going to light up. It never got hot to the touch. Even without the water cooling system and after the hill climbs. One thing I did really like were the brakes. They were mellower than the car ESC, but the nice thing was no noise. I always hated riding late through the neighborhood because the horrible noise the brakes made. I do wonder if that is something that can be programmed into the firmware like someone posted a while back.
I looked into the HV boat ESCs tonight. Still more expensive than the car version, biggest issue was if they had brakes and some were opto. The thought of having to add another battery - more things to hide - turns me off from that. Might need to figure out how a ubec works. That was another nice thing about the boat ESC - the size. You could glue it to the board if you wanted, much smaller. I have thought of removing the fan on the 150a car ESC and replacing it with some kind of heat sink to get the size down. There were a few interesting fan ideas on ebikes that I liked, having a fan on the end of the motor to cool everything off.
I will try to put some more miles on the boat ESC to see how long it lasts.
