Smoking ESC

True. The wires on my ESCs are short and thicker then most of the Schulze ESCs and only their big dogs use 2 wires. The problem was what you pointed out before.

Is it okay to put 2 additional capacitors even though it does not match the stockers? The 2 additional caps are rated for 35V, 105*C, 2200uF. These were given to me by killajb.

Yes.

Thanks. Now I can solder them tomorrow. I was just making sure that it's okay to do so.

Here are some pictures of the 3mm aluminum plate I cut and installed on the bottom of the ESC. I also added the 2200 caps killajb gave me. Performance wise, I got the ESC temps to 150*F, motor at 112*F, and batteries 98*F yesterday. This was stop and go running on asphalt. I also experienced hesitation when I tried to run wot. Batteries are Neuenergy 25C 5000mah.

Anyway, here are some pictures:



Also glued a piece of rubber underneath the aluminum plate.


Added caps on the power wire. I also shrink-wrapped the standoffs.








I also installed some plastic spacers to clear the capacitor wires. The spacers widened the gap between the board and mounting plate. Better airflow for better cooling. The gap is about 3/8".




Gap before I installed the plastic spacers.
