what are you guys using?

I was trying to think of another way to hold those packs in as well.. i guess if you have all the exact same packs you could make a clamp type system.. but I was thinking two rubber straps (mini bungie cords) that just hook over the battery; one in each direction. slide out the rubber straps battery back on again, one side always attached.. the other can come loose... Tekno v3 upgrade ;P
