Any Idea can become a Reality
Power redundancy for radio control receiver are important part of protecting your investment on R/C models. However, by providing redundant power to your R/C system, understanding the need of protection circuitry between sources is important especially in parralleling them. Without proper protection between power sources can lead to permanent if not immediate, latent damage such as to battery packs and battery eliminator circuits.
Western Robotics provides protection circuitry for such applications and also safe power distribution of mixing high and low voltages.
