Best battery type for radio controlled aircraft?

[John Doe]

I am impressed by the rapid improvement of NiMH batteries. I was told
that Lipoly batteries are better for radio controlled aircraft. After
doing a little research, I noticed they might be poorly designed and
hazardous in the sizes required. But I like the voltage. What about
using regular lithium batteries? The problem is still going to be
regulation, charging and discharging, isn't it? Comments about any
useful types are invited. Thank you.

 

Li-based cells are intrinsically better for aircraft because they offer
better weight/energy ratios.

Also, if you mount them correctly, you can get a rocket powered aircraft
briefly when they vent.

The Li based cells that don't explode from, time to time, usually don't
have as high of a mximum current. For short blasts of high current NiCad
or NiMH batteries may be better.

Are you using this for an electric powered RC model, or to power the
receiver?

At any rate, the LiIon batteries are getting popular for e-power, but
they have issues (but then, gasoline has issues too, you just have to
pay attention to them).
