A Universal Battery Eliminator Circuit (UBEC) is a small electronic device that provides a stable voltage to power electronics, even when the main power source (like a battery) varies in voltage. This UBEC will take high-voltage (5.5V to 26 V) power from your battery pack and convert it to a consistent safe voltage for your do-it-yourself (DIY) projects. Thus, this UBEC act as a voltage regulator that ensures your sensitive electronics, such as receivers in remote-controlled cars or drones, get a consistent power supply without being affected by changes in the battery voltage. It "eliminates" the need for separate batteries for different parts of a system by providing a steady power output, making things simpler and safer.
