If you look around you will find 3M strapping tape, 3/4" wide in a dispenser like the roll of tape you wrap christmas presents with (Scotch?). I have also converted a Desk tape dispenser to hold a roll of strapping tape. Just makes it easier. You will find 3M makes the best tape, other brands are harder to work with.

I race a Carpet Knife in 1/12, so I don't need tape, but still race a 10L3T.

Taping batteries in is a pain in the butt, ask anyone here. It does hold them in better than most other ways. Velcro works, but they are not in as tight and I don't want the heaviest part of my car shifting at all!
