At last! It's done!
Wire routing was a challenge with the Quark, but I think it'll work just fine.

And finally, a pic of the balancer Y adaptor. I made the leads quite long so the batts can sit in my Liposack without having the balancer crammed up against the sack.
The Quark is thermal-epoxied to a 1/16" thick sheet of 6061 Aluminum with a couple of
these heatsinks epoxied to the sheet. I wasn't sure if 1/16" thick Al would transfer heat fast enough, but temps between the sinks and the ESC case are very close. And the sheet allowed me to secure it to the ESC mount without using zipties. Yay!
