Anyone heard of Air thunder lipos?

My buddy called me and told me about his fun the past few days.....

They claim there packs dont puff, My buddy was just telling me about these in his planes, and he says they work well, and he runs no cut off..... He runs them down darn low (around 2-2.4 volts a cell in a 6s 2200 mah pack)


Just wondering if anyone has used them in there cars, or even heard about them?

Sounds pretty cool, but I wonder if they would work in a truck (Id borrow one of his packs, but all he has is the 6S 2200 packs)
