i was driving fast brakes locked and stopped the batterys unplugged so i plug them back in and poof! smoke pours from the case. berne at cc said to send it directly to the engineers. so i hope its a fluke!

Judging from your description of the accident, I think you're lucky that the battery unplugged itself initially. It sounds like some FETs were shorted (shunted?) somehow and caused the truck to slam on the brakes. I think it would've caught fire with the body on had the battery not been unplugged. Which would've been far worse since the truck was probably some distance away from you when it happened.

Why is it that every one of these V3 failures has been a complete torture test of the ESC?

Agree with you on that. I see no reason to run everything as close to the limits as possible then wonder why it fails.

Me and my sweater-knitting friends take offense to that! Some of the members knit far faster than you can drive!

I had a double-take on your S/N to make sure it wasn't James that posted the quoted message!

Did you say six 2s lipos in the car? Now that is just asking for trouble. How many sets of connectors did it require? And I assume you made 3 sets of 2 packs in parallel, which is the correct way to make 6s2p? I can easily see very bad radio glitches with that setup, and if the sudden stop was strong enough to unplug all of the batteries, then there definately was a flaw in securing your batteries. You can easily damage something on the esc if you pull perpendicular to the direction the MMM bullets are supposed to plug in and out, which easily could have happened.
