60C really?

[lutach]

You know, if the MA packs I had for some reason burst into flames, I would definitely say this thread wouldn't be here at all.

I usually jump on crazy claims such as a ESC that can do 400A to the one that states 780A. Can they prove it, no why, because it's impossible for such little devices to put out that kind of AMPs. I tell everyone if a ESC has a real rating use it a the max continuous burst which means that will be what you see on hard acceleration and that's all. Most ESC will average from 5-20A for 1/8 scale racing depending on the voltage and correct motor used (Gearing and everything else as well). Now for a pack to claim 60C surge, I'll use that as a max burst figure that's all even if it's a number I'll never see in my RC life time. After I get a project out of the way, I'll start focusing more on my full scale electric race car and I'll show everyone what a real cell that can put out over 1500A continuous and 2 second bursts of over 3000A looks like. Now this cell has a 2V cut off and it will discharge at 240A and hold over 3V at 90% DOD. The numbers mentioned of the cell are not false as it's being used by the military.

Prove it I want to see a discharge graph - lol

I will when the time comes. I am though trying my best to get 2 smaller cells and it's tough. I should just claim I do military work and see if I can get some.

Edit: I did actually let 2 members here see the datasheet.

It's true, I am one of those members, the cells he speaks of are something else. However, I believe Lipo cells are better suited because of significantly higher energy density, and we are getting to the point with these new packs (G3's, TP 40C, etc...) that the packs are not the limiting factor anymore, or at least getting close to what we can physically use. However, that said, it DOES NOT hurt, in fact I encourage it, to have higher C ratings (as most of you would agree) for the mere fact that the battery will run cooler, last longer, and increase system efficiency as a whole.

There are new technologies coming soon that will be amazing. I know for a fact that the RC industry was one of the first to adapt to the lithium and a lot of the lithium battery manufacturers out there knows this. I've seen lab results that will only make our hobby safer and at the same time provide lithium cells with amazing power capabilities. I for one am patiently waiting and will try my best to get some of the cells to test them.

Remember the video of that fuel-cell powered 1/10 TC?
