Turnigy 5A SBEC is an advanced switching DC-DC regulator which will supply a constant 5A. It works with 2 - 7 Cell Lipoly pack and supplies a constant 5 or 6v to your receiver and is interference-free.
I went to see weather I could alter it to output a higher voltage for my servo. So I goggled the data sheet and found that the chip is rated at 3A and not 5. Very dissapointing
YOU MUST disconnect the red wire from your ESC's connection to the receiver (rx), or else you'll be giving it too much juice!!! Your other option is to wire the output directly to the item you want to power, usually the servo, along with the white signal wire coming from the rx (see File "DirectPower.jpg" or target=_blank>DirectPower.jpg).
IF your ESC has a bec you need to cut the Red wire, (opto's don't have a bec) so you don't for an opt ESC, ..........MANG do yourself a favor and forget this bec and buy an esc that has it built in, most do now, only for multi motors you need to muck about.
Can I use this bec with turnigy k-force 120A hv opto v2 5 - 12s brushless esc ? And im run cyclone power ir600 - 1500 - 50 1500kv brushless motor on edf jet 90mm with 6 turnigy tgy-9018MG metal gear servo.. on 6s lipo battery. . Please help me :'(
yes, you can use with that battery, but i would go for another choice, it looks it is a big plane, so, choose the 8A bec and also get a spare 2 cell battery (1500mah or similar) to power the bec, so, you will never get a blackout when pushing the esc to its limits and in case of low battery (flying battery) you will always be in control no matter what

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 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. Glenn.
