Highest discharge battery? (or highest power density)

I want to build a very light and powerful racing battery pack. Enerland has nice batteries but they seem to be out of business and hobby king has only a few on stock. I need a lot of small packs for a big car-sized pack (3000+ Amp discharge). Any suggestions?

Thanks!
 
Nano-Tech's will do 100C.
 
Formula 1 uses Saft battery cells for there KERS systems. They can do ~100C as well but are probably harder to get and more expensive. Based on LFP's awesome data I would say the Nano-tech are the best for cost and availability.
 
These are rated at 130C max http://thunderpowerrc.com/html/G6ProPower65CSeriesBatteries.htm

However, they are also ~ 2 times the cost compared to nano-tech's.

So to get 3000 amps burst (1500 Continuous) out of the Thunder Power's would be $1199.97 (23.1Ah)

For the same price and voltage you can get 5400 amps Burst, 2700 Continuous (60Ah)

And these are just the rated discharge abilities, a few forum members have found them capable of discharging more than the rated number.
at 100C that would give you a 6000Amp bust pack for $1199.97 at 22.2V, just scale accordingly to your voltage needs.

In addition you can charge the pack at up to 10-15C, aka whole pack from 0- >90% charged in ~4-6 min.

It would also be smart to order 5-10% more than you need so you can cherry pick the most capable batteries, as there is a good chance at least once pack will have a bad cell in a large order.


The best place to order them is directly from Hobby King, it's best to be a bit patient when you order these, so if you don't mind waiting on them to be shipped from china, there is a good chance you will get the best deal for large orders. Otherwise the local warehouse is always a good option.

Here is a few demonstration/discussion threads:

Has anyone actually made any "scientific" comparison tests between standart high discharge rate turnigy and turnigy nano?
Meaning that they are not just the same cells in a different pack... ;)
