The 20A SBEC is a must have for any model where clean, reliable power for your electronics is required. Offering a wide input voltage range of 6~50V The 20A SBEC can be used with any application from small models all the way up to 800 size helis or large gas airplanes The voltage output is selectable by jumper for 5V, 5.5V, 6V, 7V or 9V operation This unit features dual output leads which not only provides power redundancy, it also spreads the current load over two sets of leads to you are not putting too many Amps through one lead In order to better maximize product performance, when using a short-circuit plug (jumper) to switch the output voltage, please operate with the input voltage disconnected to avoid unnecessary trouble Specs: 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 Operating 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 a little different from the real thing. The measurement allowed error is +/- 1-3cm.
