well yesterday i went to the local construction site with my bl revo. i made a custom battery tray with aluminum sheet and a couple of screws. but one thing i didnt notice was that one of the button heads of the screws was popping out a bit.. after the bash i checked out the battery and thier is a small indention in the pauck... kinda like a 1 mm dent but if u run ur hand over it u can feel it.... i the pack never ran hot or warmed up.. i charged it last night and nothing got warm and everything went ok.. should i worry about this.? and yes i fixed the screw already.
