Happened during driving.
4s 5000mah 20C Zippy-H. I had driven ~30 charges with it before this happened. Temperatures been ok and all. Was on 1/8 buggy conversion with mamba monster and 2800kv xl-motor. (maybe 6 charges with this car, then with old cars, inferno and mt2) Charged with balancer and 1C or less.
