ok, I know this question comes up a lot. And yeah it is kinda noobish and very subjective.
We run 8 minute mains in 4wd and 6 minute quals. I am currently using 5mm bullets on all of my batteries. The d413 seems to be really punishing my packs. They come off the track in the main at 30%. They also get a little warm, not much, but you can feel it in your hands. My main issues are increased IR in one cell and puffing. I am using the 90c 4800 mah packs with a 6.5. Does anyone make a pack cell that holds up better and does not puff? In my experience al of these higher mah packs in the same sized cases are puffing. I am told this had to do with the tight confines of the cells in the shorty pack. The orion 100c 4500 seems like it might be a well made pack, but they are 4mm. I know the turnigy ultimates are 5mm, but I have had issues with cell failing entirely in those. Maybe I just expect my packs to last too long. thoughts?
