Medusa Research's Battery Eliminator Circuits eliminate the need for a separate battery pack to run the receiver and servos by stepping down the voltage of the main battery. Smaller, secondary battery packs are a nuisance to maintain and charge, take up valuable space, and add weight to your model. Removing them through the use of a BEC frees up the space and weight, and reduces the number of failure-prone parts. The 2 Amp BEC is specifically designed for smaller models. It is only 20x22mm, less than one square inch in size! A typical receiver and servo battery pack weighs approximately 90 grams, while the 2 Amp BEC only weighs 10! A battery eliminator circuit of this size is an industry first. Medusa Research BECs save space in your model, can boost performance by improving your thrust-to-weight ratio, and are a cost effective alternative to secondary battery packs. While the standard 5 Volts is perfect for most applications, the 2 Amp BEC is available in 6 Volts for faster servo throws. The 2 Amp BEC is also available in 9 Volts for use with mini-cameras and other 9V accessories and should not be used to power standard 5V equipment.
