Li-poly batteries for receiver?
I know most people use Li-poly batteries for electric planes and Li-ion for receiver batteries. Is there any reason why you shouldn't use Li-poly batteries for receiver batteries in giant scale gas planes?

I belive the lipoly deliver high current discharge i guess.
Anyone ? |

I don't think it would matter.. In fact Aircraft International is advertising this http://www.aircraftinternational.com...2800/index.htm ... It uses Li-Poly batteries. Of course you will need regulators if you use Li-poly. I think it's only a matter of time before people switch over, the flat design would make some radio installations easy.

Li-Poly's work without issue. The thing that concerns most is their fragile nature as compared to Li-Ion in this enviroment.
Poly is wrapped in a mylar semi soft housing and is susceptible punctures. Poly has no provisions for venting the cells. Poly power tabs are fragile and must be secured or assembled in such a fashion to prevent fracture form the vibration of gassers. Thermal runaway is a possibility and since there is no vent, I'd suggest you remove them from the model while charging as a precaution. All that said, many people are using them. Modelbau and Emcotec offer specially assembled Li-Poly cells with housings and charge protection circuits built-in for our needs. |

You could use them, But if they are in a high vibration environment, it might do damage to the LI-POLY battery. Why not Lithium Ion? I know Fromeco sells them real cheap, and they are awesome!

From what I have been told is that the tabs will fatigue from vibration. I hear ThunderPower is working on this but no idea when something would be available.

I used these in my 50cc wild hare edge 540 and in the plastic case they are very tough and easy to fasten in with velcro and remove and with a smartfly they offer 10,000 ma of redundant power.

RE: Li-poly batteries for receiver?
I use them in all my fuel planes. Some are small 2 cells and some are bigger 3 cells.
I have had Lipo battery tabs break but never in a aircraft. If I really beat the living C_ _ P out of my RC truck it is possible that the battery tab/circuit board will shatter. I can not imagine that a aircraft would be able to damage one unless you lawn dart it. |
RE: Li-poly batteries for receiver?
the biggest reason i don't use Lipos,they can cause a fire when recharging,you have to remove them from plane to do so.and they are just to to fragile as already said.
it is safer, better and easier to use A123's |
