You'd be surprised how much current you can pull! In my truggy on 5s geared for about 38MPH I had peaks over 160Amps. These MA packs should do great at those current levels, according to the label!!! However I don't beleive their labels as I severely puffed a 5s 5000mah pack in that truck after I lowered the gearing

The part of the test i found the most rediculous was the fact that they gave the turnigy pack a 5th place rating in the capacity test, when in fact it held 80mah more than it is rated for. The winner of the capacity test actually held 60mah LESS than it was rated for. Does that make ANY sense at all? In my eyes the Turnigy pack won that section of the shootout hands down! However the seat of the pants test the Turnigy came in dead last, but i would still attribute part of that to the low C rating and capacity size.

More than likely. However, they can only test what they are sent. Personally I think they need to in future shootouts set a specific # of cells, MaH, and C (even though this is subjective as we all know) rating so that its a more even playing field. Nonetheless, seat of the pants testing will always be subjective.

True, but BigSquid chose that 4500mah pack to test, why didnt they choose to test a bigger pack? HK didnt send them a test pack, im sure it was bought off their website just like everyone else buys them. Turnigy do have 5800mah packs, but i dont know what the c rating is on those.

Something just occured to me, maybe since all the packs they tested were hardcase, that that is the biggest hardcase pack turnigy makes? That would make sense. Now im going to have to go look and see......
EDIT: ok so yes that must be the biggest hardcase turnigy makes.

Actually I don't know. In at least the first two tests I do believe they were supplied by the manf. with the batteries based on their test vehicle. I'm not sure if they purchased this round or not.

Ah, yes, that would be the reason. I think I was more interested to see the graphs than anything. I would have preferred them do at least 3 runs per battery for the graphs.

Same here, i didnt read much of it at all, i just scanned it real quick and looked at the graphs. Maybe i should read before i get all excited? lol. But honestly they should have taken the C rating and mah capacity into consideration before coming up with the results. OR they should have gotten packs that were much more comparable whether they were hardcase or not. What is the big deal with the hardcase packs anyway? I have never seen a hardcase lipo in person, but from the pictures i have seen of the case material it looks pretty thin and flimsy.

I have a bunch of 2S lipos that are hardcase... they are ok.

The "Deal" with hardcase is that all 2S and 4S lipo packs (only type used) have to be "hardcase" by ROAR specs for ROAR racing. SO might mean something to "racer" crowd (i'd be one but I can't make 5pm start times with being over hour away) but not for the more basher oriented crowd.
