Voltage Range for the 9C
Does anyone know if the Futaba 9C can be powered by a three (3) cell lithium Poly pack. The peak voltage of a 3S pack would be 12.6 volts.
Thanks
Thanks

RE: Voltage Range for the 9C
That seems too high to me. Considering the regular pack is 9.6-12v. I wouldn't risk it. Replacement batteries are cheap... replacement 9C's aren't. 
I thought someone made a lithium TX pack? I can't remember where, maybe run a search and see if you find something.

RE: Voltage Range for the 9C
its going to be very close though, a fully charged 8 cell nimh tops out over 11 volts already, so why not just put a diode string in there to drop the voltage a little...

RE: Voltage Range for the 9C
I have had one in mine for almost a year. No problem. They are all made to work off of alkalines which are also 12 volts. The battery in my 9c is from Duralite. I have used others in different transmitters with no problems.

I can see LiP's used in small planes, but why buy problems for a transmitter? Inquiring minds want to know.

Ditto on the Durallite. It has a regulator.

NOT quite... Duralite uses their charge safe circuit, no regulator is in place...
You'll see somewhere near four hours use with the Lithium-Ion cells.
Poly is not used by anyone for TX batteries to the best of my knowledge.

15 degrees? What is that, Celsius?

RE: Voltage Range for the 9C
From what I understand, the 9C uses regulators to get the voltage it needs.
I don't see where it would be an issue but you need to check with Futaba

I believe he is right on all three
No, it is fahrenheit
