Lipo-impact damage?

[Papa]

Let me start by saying I have Zero first hand experience with the Lipo packs. I feel like impact damage is a reasonable concern. The only counsel that I have received is to utilize Associated battery cups for mounting in a Gmaxx chassis. I have heard stories of The normal Velcro straps creating impressions on ends of lipo packs when tightened to much. The IMPAD sounds like a good idea. I have seen them used as endcaps, and as pouches for lipo packs. I am worried about how the padding would effect the temperature of the packs. Additionaly I have visions of all the little projectiles thrown up at the packs, from the tires, poking holes in the packs.I can not help but to think some hack may t - bone my rig and slaughter these expensive packs. I guess Its just hold on and pray.

Basically I have 4 options

1 Impad and Gmaxx straps.
2 Associated battery cups.
3 Zip ties and a prayer
4 Velcro on packs and a Gmaxx CF rigid battery strap

I am undecide as to what to do?
