NCR18650B - The Future of RC Aircraft Batteries?

NCR18650B: A Lithium Ion battery with a ton of promise! People say it has twice the energy per gram as LiPos... but is that true? Lets test it!

But it doesn't stop there! I want to know how to actually use this on an RC Aircraft, how to charge it, what it's maximum amp draw is, how many watt hours of power does it have, and in the end, can you actually use these on RC aircraft?

I think I've found the answers to these questions! 

Battery: Panasonic NCR18650B
Grams per Watt Hours is 57% that of a typical LiPo
Pack Capacity: 3.3Ah (3,325mah)
Pack Voltage in 4S: 14.4v
Pack Power: 43 watt hours (personally tested with a watt meter)
Pack C-Rating: 2 (6amp max discharge rate)
Pack 
Cycles: Hundreds! I've not personally tested this, but this is the same chemistry as an iPhone, which can last years of daily use.

2C? What motors you are power with this rate?

Dave: Thank you! I'm excited to start using them on the 140C.

Gary: Thank you sir! It was (as always) an awesome time. Really enjoy this kind of stuff...

Vladimir: The Raptor100 draws 44watts at cruise (it uses a 2826 1400kv), which is 3A on a 14.4v, which is 0.9C. When the 140C has six of these, it will be 0.5C for each cell, while cruising at 85kph.

Great!

My smallest plane draw ~8A on calm condition. And about 36A on take-off. Questions?

Vladimir: Thats quite a bit of draw for a small airplane. I guess what is small to you : )

Small? 160 g weight? Do you remember - planes is flew, not crawl...

Hi Trent, I used them for my 2h06m/116km flight, they really work well, got another 100 cells on their way.

Very exciting stuff! Thanks!

Graham: Yeah! you and others inspired this video! Thank you for blazing the trail.
Jethro: I agree! I can't to see them all working in parallel on the 140C.
