Yeah as others have said, ditch the switch and add a fuse and LED. Should be good to go. You can get away with a battery half that capacity and use the weight for armour. Also make sure to cut the power on one of the receiver cables or you'll blow it up.
No idea how i didn't blow up my receiver when i had 3 ESC plugged in when i didn't know that the two old FR15HX did have a BEC.
