AAA Batteries - Best Performance?

I need to buy some new AAA, 700 mAh, rechargeable batteries. I've pretty much narrowed down the choice to NI MH or LiFePo4. Both have better life spans than my old batteries which have given up the ghost. I am leaning toward the LiFePo4 batteries. They are to be used in the transmitter of an Hubsan X4. Which would you choose and why, or which are you using?

Thanks,

Cliff.

The various opinions that I got elsewhere seem to indicate going for the NI MH batteries for the transmitter. The next question then that comes up is what capacity?
 
What voltage will the TX take? Have you opened it up to see if it has a voltage range listed somewhere?
 
700 mAh are needed. Couldn't find all that easily, but did come across some 730 mAh NI MH made by Sanyo. I'm hoping that they are interchangeable. I'll have to look up their physical dimensions online,

I assume you need 4? The mAh has not nothing to do with it, only voltage matters. If it's AAA size you need, any AAA will do. Get the highest mAh you can find. That said the China ones seem to exaggerate mAh and sometimes can be a tad shorter.

Jackson, thank you very much. I've not had to deal with "electric" flying in the past, so this is all new to this olde gopher.
 
If the transmitter requires 4 batteries, means 6 volts is the nominal requirement, it will probably accept a little less as batteries drop in voltage.
Rechargeable AAA's are 1.2 volts each (nominal voltage). You could have very short life with rechargeables if the TX is not prepared for it.
Seen it with many devices, using normal batteries is the way to go if you need a longer lifespan out of it.
 
No worries then, just thought I'd give a heads up :)
Proffesional deformation, I guess. About 50% of the complaints I get at work (QA engineer) are related to rechargeable batteries.
