Try to make the story short....I wanted an ice 240 in my Rivercat im building. Well they don't make them anymore as you all know, but I found out quite some time back that a mamba xl2 is the exact same esc except (per castle and I have a burnt one I compared to confirm this) the top shell is different because it's air cooled and the firmware is a little different. I prefer how a car based esc drives anyway, so a plus for me. So I picked up a mamba xl2 and decided to water cool it. Me being me, I couldn't just epoxy some tubing to it and call it a day. No. I had to make crap complicated as I usually do lol. I wanted to show what I ended up with as it looks pretty cool I think.
First off I changed the caps on the board. It can with 35v caps. Hmmm. Common sense tells me it's probably not so good to cut it that close, especially if I run 8s through the thing. Sitting voltage with hv cells is 34.16v. Too close for me. So in went 50v caps. Then I lightly coated the whole circuit boards with clear epoxy like I use on everything else. This things are known for going out if water if thinks about getting close. Next I milled off the Fins to make way for two cooling blocks I milled.
Then here's the cooling blocks.
