A123 Power

I was wondering if anyone is flying electric foam planes with A123 LiFe batteries rather than Lipos. I know all about the advantages and disadvantages of each but would like to see some planes that are flying with the LiFe batteries. Someone must be doing it, or has tried... Thanks.

Since you asked in the 3D section, I doubt anyone is flying 3D with A123 Systems LiFePO4 batteries. The weight penalty is too great.

That being said, almost my entire fleet is powered by A123 cells, as I do not fly 3D, just sport and sport scale.

Look in the Batteries section for a lot more information on real A123 System cells and what they can power.

I had success flying a Gary Wright E3D on A123's. I used 4 cell 2300 packs on a Mega 22/20/2 in a MEC Super Box. I had to adjust the ratio slightly but it worked great but remember that plane was designed back when round cells were the go-to battery and it was designed around a 10cell CP2400 pack. I tried the same pack on a Steven Aero Edge (not a good 3D plane) and the Edge did not like the extra weight.

Cheers,
Jim
