AE Battery Cups

[Re~Mix]

I know hundreds of people have used these on their nitro -> electric conversions just as I did. I just have one question. Earlier I ran into a curb at about 1/4 speed and the batteries just flung out bending batt bars and all. Maybe I should be shoo-gooing these things together to make it so that doesn't happen?

I'm looking to purchase gorillamaxx straps, will those help hold these things in place, because the 1/8th is nearly indestructable by itself, so I want to narrow down the week points in my setup.
