Well, the TrakPowers ideally should have been glued together, then shrinkwrapped (or skip the shrinkwrap). As long as you keep the shrinkwrap on they should be safe enough. I still think they should start glueing the halves together in the future though.
I'm not sure how they handhold this in the US, maybe they demand that the shrinkwrap is not removed. And there's the "ROAR approved" sticker, I don't recall right now - is it outside or inside the shrinkwrap? (I think it's on the outside)
I managed to dump with new & matched 4600 cells this summer... with 5 cells and 5,5 in 4WD on the wet clay track (=Nutella) in Vaasa, Finland. Barely made it with 6 cells
