Absolutely hilarious.

By the way, SMC batteries are simply awesome, thanks for a great product Danny.

Danny,

TP says they took an SMC pack that had the following on the box (from your GFX):

537 - 7.43 - 5.4

and got this on their GFX

529 - 7.38 - 6.8.

Clearly, that's much less favorable numbers than your own GFX produced. Then, on the same unit they tested their pack, and got

507 - 7.44 - 5.7

That tells me that your GFX measures things much higher than TP's GFX. So, it stands to reason that a TP on your GFX would also be higher, since they're being compared on the same units.

Yet, when you measured the TP pack, surprisingly, it's much lower than what TP got, rather than higher, as you'd expect.

514 - 7.40 -6.5


So what's going on? Which one of you guys has the magical GFX that makes your own stuff look more favorable than the other guy's?

That is why I said it was funny in my post.

There are many factors than can influence Lipos. One of them is age combined with storage charge. I assume TP got our packs from one of our distirbutors or a hobbyshop. So the packs could of been sitting for as little as a few weeks or a few months.

My test today is on the new TP pack bought from them last Thursday via a friend. I assume since these packs are new they must not of been sitting inactive for a long time. Our 4 sample packs are new as well so my tests should be fairly accurate.

The TP pack didn't have any numbers on it so I can't say if there better or worse but based on the pack TP tested the one I got was lower.

Danny, can you comment on the performance difference between the 4000 and the 5000 28c packs (or better yet the 3200 and 5000 40c's) for Superstock 13.5/19T racing?

In spec racing, you're only pulling out roughly 1/2 of the battery charge, so it would be the first 2500 mAh part of the discharge curve that would be considered here. Is the performance of the 5000 still 0.1V and 2IR points better across that range?

I can vouch for this test. I was there and, quite frankly, was surprised at the results based on the numbers posted from TP. Perhaps another day, another result. We cycled all the packs twice to be sure it wasn't a fluke. Once again, the best thing to do is run the packs and see what performs best on the track.

I will only be able to comment on the new packs differences and performance when we get them in. At the moment were waiting to know exactly what were coming out with.


Attached is a graph of our 4000 and 5000 28C packs. Using the GFX at 35 amp discharge. You will notice the voltage is better on the 5000 but we have had racers who tried both and say ontrack performance is very similar.

The length and width is the same as ROAR but the height is 23.5 instead of 25.1.

It's a shame that RC santioning bodies around the world have different rules/sizes.
