This small and lightweight UBEC features a high efficiency switch mode design providing better heat dissipation when compared to the linear voltage regulators. The 3.3V output is ideal for use with robotics, LED and DIY projects. The shielded PCB design and output EMF coil makes helps provide a stable and low noise voltage output. This UBEC also features built-in reverse polarity protection.
Input: 7V-23V (2-5S Lipoly, 3-6S Li-Fe or 5-15S NiXX Battery Pack)
Output: 3.3V/3.5A (Less than 50mV peak to peak voltage @ 2A)
Dimension: 47mm x 25.2mm x 10.8mm (LxWxH)
Weight: 11.7g (wires included)

It doesn't work at 6V at all. I checked it with a multimeter, and at 7.4V it has 3.3V output, but with less than 7.4V the output drastically decreases and becomes unreliable. I'm disappointed because I bought it for step down 6V to 3.3V, but it can't do it. Specs should be corrected. I'm also unsure if this can keep the 3.3V voltage when a 2S lipo gets discharged.
