e-revo - 5s lipo - up in smoke :(

I love the true RC lipo, it has never gotten above ambient temp. The drivetrain was fine, temps were air 85, batts 86, motor 115, esc fried

The motor is a 1515 1y, and lutach that is exactly what happened. I went to unplug the battery (which is ok) and the wire came right out
