LiFe 6.6v for reciever applications
Hi, wondering if you could clear up some confusion for me. I normally use a 4.8V Nicad to power my recievers. I see where some manufactures are now promoting 6.6V LiFePo to run the recievers. One company includes two plugs to be used on the reciever(?) for high capacity loads. I normally fly 6-8 standard size servos in my planes. I use the Berg Microstamp 4 and the Berg 7P recievers. I was always told you had to run at least 4.8V to run the flight pack. Will 3.3V run the set up, or do I have to go to the 6.6V? Will the Berg recievers handle 6.6V? If so, how do you recommend hooking up 6.6V using this power source? Is a regulator needed? Thanks,

The Berg will operate just fine at either 6.6V or 3.3V. There is an internal 3.3V regulator in the Berg for the electronics, and that regulator will operate to about 10V of input voltage.
The electronics will operate down to below 2.8V.
That said, please make sure your SERVOS work correctly at the voltage you are planning to use. Usually servos are much more sensitive to voltage than receivers.

The hard part is determining how much current you really need. Few servo manufactures are forthcoming with thier current draw ratings. Even those that supply the rating tend to be slightly off. At least in my experience. The best thing to do is run your own test with an amp meter or an Eagle tree and find out what your application is drawing.
