in the last days i heard that those bat arent the right way to to use them in a jet(radio system)
with 8-9 servo or more(that 6 of them digital servos)
is it true
thak you

Fromeco batteries are a great source of power for jets. You may want to increase the mah on the pack though for better peice of mind.

I am running 2 4800 mah Lion with 6v regulators on a bandt arf - can fly all day long. Never have had an issue with the batteries, over 75 flights on them. I am also powering my BVM F100 with 2 5200 mah lions from fromeco with 6v regs.

Good luck.

Udi, I use the 2600 Fromeco's in ALL my jets, except I have two of them powering the rx. I have had no problems at all, but have never just used one battery.

Why would you not want to increase the MAH of the pack? A Fromeco 5200 MAH pack is lighter and smaller than any 5200 NIMH that I have ever seen. Do you have another reason to not go more MAH? Sounds like a good answer to the concern you stated in your question. I use either 2 Fromeco 2400 or a single 5200 to power all of my jets radio systems with one or two regs.

I've used Fromeco 2600 in 2 jets by themselves. However it was 72mhz not 2.4. I have never had a problem. I just converted one jet to 2.4 and upgraded to 5200 mah. My other jet will use a 2600 on 2.4 but I will use the dual input regulator with the 16ga wire and deans plugs. None of my jets draw over 2.5 amps when loaded up. Idle current is about 1 amp max.

I have 2 of the 4800 MAH Fromeco batteries with 6 volt regulators powering 14 servos (12 of which are high power digital) in an Ultimate Biplane. Those servos get more of a workout doing 3D manuvers than servos in jet will ever see. Absolutley the best insurance for reliabilty that you can have.....but thats just my opinion....I could be wrong.

Look into Fromeco's new line of Iron Corps batteries they are similar to the A123 cells. The A123 can handle a bigger discharge in amps then the Iron Corps. Iron Corps can handle a bigger discharge in amps then Relion(Lith Ion) packs. Seem to be priced well.

From Fromceco website

The Iron Corps 3600mAh Lithium Phosphate Pack.
The Iron Corps 3600 is recommended for RX service in Giant Scale Planes, and Helicopters.
Fromeco's Iron Corps batteries utilizing the new Lithium Phosphate (LiFePO4) technology. Iron Corps cells share the same basic chemistry as the well know "A123â„¢" batteries.
Iron Corps batteries are not quite as strong as the "A123â„¢" branded cells for amperage output. However they are plenty strong for flight RX applications. Fromeco tested many different brands of LiFePO4 cells in search of a cell that behaved much like the "A123â„¢" cell.
These characteristics are;

High amperage output

Flat discharge curve under high load

Lack of a predominate voltage loss at the end of discharge

High Charge Rate

Voltage between 5.0volts and 6.6volts while under a high dishcarge load

7.5volt terminiation for charging
Like the "A123â„¢" cells Iron Corps share these characteristics, at an affordable price

I use dual Fromeco 2600s thru a PowerBox in my F-15 and it's fine. I have over 200 flights on it with no problems. I completely wore out a set of 8611s on the stabs and now use 8711s with no problems at all.
