The only advantage of "true" A123 cells are if you intend to use them for primary motor power in an electric. In low current draw uses like transmitter and even receivers, the prismatic flat LiFePO4 cells are superb. They are lighter, have a better form function (shape), come in a wider variety of capacities, and still provide 5C discharge and in many cases up to 4C charge (Hyperion cells).

What's not to like??

I have been using the Hobbico flat LiFePO4 cells and the A123 cylinders with great success; they are both great for receiver applications.

I will continue to use them in the future. All my big planes have the separate receiver packs.

I really like to use a receiver battery separate from the power system. It makes testing of the control surfaces and electronics safer when you don't have the possibility of accidentally arming the power system as you might with BEC systems.

How does one set up a LiFe running the RX and svxs.. but a LiPo or A123 running the motor and ESC.?????
Probably a dumb question, but.... I worked hard on my planes and I don't wanna trash them!
Thanks for any tips or links.

Jack it is simple. You simply disable your BEC in your ESC by removing the red wire that goes from your speed controller to the receiver. This will disable its ability to provide power through the BEC built into the ESC.

Then you use the LiFe battery by plugging it into the battery (or any other unused) channel.

My B & D A123 1100 mahr cells weigh 1.4 oz. Where is the weight savings. There are at least from 2007 or earlier.

I am a little unclear about what chargers can be used to recharge these packs? Can the Hobbico Triton do it or do you have to buy the "special" Hobbico LiFeSource AC/DC Balancing Charger? The Triton is listed as being able to handle the following chemistries:

Charges 1-14 cell NiMH and NiCd cells and 1-6 cell LiPo, Li-Ion and LiFe (3.6, 3.7 or 3.3V cells)

SO, is the LiFe chemistry listed in the above quote the one that applies to these batteries?

Thanks!

LiFePO4 = LiFe = A123 (Brand Name) = LiFeSource (Brand Name). Construction of the cells vary, but the charging voltage/method is the same.

The Triton charger can safely charge the LiFeSource chemistry at the correct voltage. You don't have to buy the "special" charger.

I have been using my Triton EQ and my Revolectrix Cellpro PowerLab 8 (PL8) to charge A123's, and LiFeSource; No problems. The PL8 does a nice job of gently charging the packs, and I prefer that to all other chargers.

I have a small plane an i am running an old Futaba NiCd 4-Cell 4.8V 600mAh Square Receiver battery in it. i get about 5, 10 min. flights out of the plane before that battery reaches danger zone. I am thinking about buy a life battery to use in the plane, but not sure which mAh would be my best choice, i would want the plane to do at lease 10 flights before charging..

Next thing, i was looking at this battery from Hobby King: Turnigy nano-tech 2100mAh 2S1P 20~40C LiFePo4 Receiver Pack.
http://www.hobbyking.com/hobbyking/s...iver_Pack.html

An was wondering it this pack would give me my 10, 10min. flights. let me know what you think guys..

Thanks all..!
