well im a noob to rc cars and so ive kind of relyed on my buddy who has been into it for about three years. he runs the exact same pack in his slash and sc10. he's running the stock setup currently too. so im pretty sure im good on the battery. no i havent gone through any water. the only water its seen is when ive washed it. and i take all the electronics out when i do, and barely hit the motor with any water at all..
