ElectroDynamics Pow'r Back'R
The ElectroDynamic Pow'R Back'R EDR-108 uses two 6.0 - 6.6V Battery Packs and two Switches which can be purchased seperately to provide Dual-Redundant security for your aircraft system.
With the Pow'R Back'R, you can tolerate a single failure (open-circuit, short-circuit, low voltage) in either battery pack, switch, or battery wiring, without losing radio control.
The Pow'R Back'R continually monitors both battery packs and switches for the one with the higher voltage, and routes that to your Rx and servos. Pow'R Back'R is still the ONLY Redundant Battery system currently on the market that offers TRUE "ground isolation" between the two batteries.
You may combine different size packs. In practice, with two good packs, the system draws power equally from both packs, adding their individual capacities.
I.e., if Battery #1 is a 6V/600mAH pack, and Battery #2 is a 6V/1200mAH pack, you will have an 1800mAH power supply onboard, with at least 600mAH to fly on, in case of a failure.
