Welcome to the store! The 20A SBEC is a must-have for any model where clean, reliable power for your electronics is required. Offers a wide input voltage range of 6~50V. The 20A SBEC can be used with all applications from small models all the way up to 800 size helis or large gas airplanes. The voltage output is selectable with a jumper for 5V, 5.5V, 6V, 7V or 9V operation. This unit has dual output leads which not only provide power redundancy, they also spread the current load over two sets of wires so you are not putting too many amps through one wire. To better maximize product performance, when using a short-circuit plug (jumper) to switch the output voltage, please use it with the input voltage disconnected to avoid unnecessary problems. Specifications: Max current: 20A Input voltage: 2-12S Output voltage: Jumper selectable 5V/5.5V/6V/7V/9V (No programming required) Input current: 6V -50.4V (2-12S lithium batteries) Wide voltage range: 6V-50.4V color: Black Material: plastic+metal Package Contents: 1*BEC Power Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture to be slightly different from the real thing. The allowed measurement error is +/- 1-3 cm.
