The TURNIGY 3A UBEC utilises switching technology to gain a much higher efficiency than a linear BEC, this means less heat and longer battery life. The UBEC is equiped with a noise reduction alloy housing to reduce noise even further. Incorrect polarity safety feature ensures the UBEC will not be destroyed should the battery be connected incorrectly.
Features: • Over current and over heat protection. • Switching frequency 300khz. • 92% chip efficiency • Noise reduction alloy housing
Hello, I'm a bit confused about the maximum input voltage. The product page here states it's up to 5s, but the label in the back of mine says it's up to 6s. Has anyone successfully tried on a fully charged 6s LiPo?
I bought one of this with some other products for a total of $94 (order ID 2008746381), they charged my credit card but never shipped anything. They have told me in several occasions that they are not willing to make a refund. I have heard several people are having these kind of issues. I warn you not to trust this store anymore!!
I have ordered hundreds of dollars of products from Hobbyking and so far they shipped what I have ordered. If in doubt, get online with the customer support. I have full confidence they will get it sorted out.
hi all, i have an old speed controller (turnigy multistar 20amp) and it has a sbec in it(5.5v 4A). could i use this as a bec to power only my reciever in a nitro car. i can solder off the motor wires. the reciever im using is the hk-gt2. i am running 2 servos. help would be greatly appreciated.
Very tiny module. I was expecting a little bigger... It came in transparent shrink wrap.
The output wire has a JR battery terminal. The input terminal has no connectors attached, so you can attach the connect of your choice.
Actually weights 8gms
I am using 5 Futaba 3004 servs without any problems. IT barely gets warm.
Suggest to keep a min 10cm distance form the reciever to avoid interference.

I checked this UBEC on a spectrum analyser to see wether it put out lots of interference in the 35 MHz radio frequency band. There is some switching noise between 100 Khz and about 2 Mhz, which is to be expected as this is the main switching frequency and the harmonics of it. I was able to lower the noise by winding 2 extra turns of cable on the ferrite core. If you want it REALLY quiet, you can solder a small 4,7 uF Tantalum capacitor between the red and the black cable. Mine fits nicely inside the ferrite ring. But I guess these alterations reflect just my tendency to perfectionism. It would be interesting to do some comparative range testing with this UBEC vs. a receiver battery. Maybe when the wether gets warmer...

Very BAD PRODUCT.. The Cable is so Thin..!! i bought 1 of these and tested to my Turnigy Lipo 1300mah, than the Cable BURNING..!!

Poor quality. Have after some tests sometimes no output voltage. Just one time is to mutch. Thank god, i don`t have crashed my full glass EP-warbird with this BEC. I took another BEC.
Dont agree that this is photographed and labeled, 5A UBEC but when you get it, the instructions state 3 amps. Labeling a device that says UBEC - 5A but not stating 5A amps for 10sec is not right. It's rating is 3 Amps Constant, so it sould be labeled as shuch. I purchaed 2 of these thinking that I got nice small UBEC running at 5 amnps.. Wrong!!!
