Precise elements of a drone need 5 volts or 6 volts of regulated and clean voltage. Using this device, get clean voltage for FPV or any other applications.

Designed with an advanced switch-mode DC-DC regulator IC
The output is powerful even when working with 4 to 6-cell LiPo batteries
Battery polarity reversal protection
A metal shield covers almost all the electronic components, and a specially made filter is
attached to the output wires to significantly reduce electromagnetic interference
The working status is shown by an indicator (LED), which lights when the output is in the normal range
Item: 3A-UBEC
Output Voltage: 5V or 6V (Changeable with an output-voltage select switch )
Continuous output current: 3 Amps
Input: 5.5V-26V (2-6 cell lithium battery pack or 5-18 cell NiMH/NiCd battery)
Size: 42mm (L) * 24mm (W) * 11mm (H)
