It weighs so little it wont have a lot of inertia. I put a bracket/rail and sponge strips to hold it between the back of the bulkhead and bracket, and ran a strap beneath the bracket/rail to loop over the top and hold it in.
Agreed, and as I said before there seems to be no agreed system of specification!
However, the Anti gravity battery has not let me down yet and I am convinced it is the most cost effective way of shedding weight. It is an awesome thing!
