i am modng a nerd gun to run off a 2s lipo is this what i need to prevent draining my lipo

No. this will only drop the 8-26 volts from the battery to either 5 or 6 volts. You need a low voltage cutoff or alarm such as ....Product ID: Voltage-Alarm or DL-Volt-Alarm .

can i used this BEC if i use the Parallel plug i want to use 2x 3s 2200Mah making 4400 mah.

Yes. It doesn't care about the mAh flowing through it, it just cares about the voltage being applied.

what gauge are the input and output leads
 Vern 62 points
looks to be almost the same gauge as servo wires

can I use this with Afro esc slim 20a? and cc3d flight control?
 hiteknut 27 points
yes it will Daniel,just remove red wire from all esc receiver connectors before you plug in the bec to receiver. i am using 3 afro 20a with kk2.0 and 2800mah dst1200`s 9x4.7slowfly and this bec and it works great . hope this helps.

can i use UPS battery 12 volt, 7.0 AH for UBEC input, and use output for my Skyzone receiver (5volt) ?
 kr4mt@suddenlink 41 points
Depending on which skyline receiver you have, from what I can see in the specs the highest current rating on any of the skyline receivers is 500ma at 5 volts so I can see no reason you wouldn't be able to do so. This unit is rated at 5 amps so you won't be overloading the BEC with that small amount of current. Just be sure you verify polarity before you connect it to your receiver.

I bought this back in January to use with my T-Rex 500, since I wanted more than 3 amps to use with a standard tail servo. Unfortunately, this BEC will not supply more than about 2.5 amps, not the advertised 5amps, without dropping voltage to less than 3 volts. I had several issues while flying, which I couldn't figure out until I hooked the BEC to an ampmeter and found out how few amps it actually supplies.I would give it 0 stars if I could.

the led begin to reduce luminosity with load > 2A, i not believe it output 5A...

I'm giving this 3 stars, as its cheap, however, the switchmode controller IC is an XL2576, rated at 3amps, not 5.

The instructions also rate it at 5amps MAX (which it will never do anyway) So I have no idea why hobby king are falsely advertising it as 5amps continuous.

The description of this switching BEC is misleading. It will supply 3A continuous, but the output voltage drops off at any current draw higher than 3 amps. The ripple voltage is also extremely high compared to others and what would be expected from a power supply of this nature. The heat created is also unacceptable. Power hungry servos like the HXT900 (at 500mA each) would stress this BEC if using 6 servos. The only good thing is the ability to handle 6 cells.

The BEC has almost 1V peak to peak switching noise at 2-3 Amps. At 5 Amps the output dropped to 3.5V. The Hextronic 3A BEC is much better.
