(Hmm...the reply button doesn't seem to be working for me here.)

tehPajka, thanks! Yes, I meant microUSB. Sorry, typed too fast there :)

I was hoping to power it through AAs because I have those lying around but no LiPo's. I guess you meant that [microUSB - anything] cable needs to be obtained elsewhere too?

I still don't understand why I'd need servo connectors in this setup.

I can also get cheap (but less cheap than here) 6AA holders locally (ordering on eBay for one item isn't worth the shipping fee) but was hoping they sell them here (in case i missed it) and I could then bundle the order with the UBEC.

The 6AA holders for 2USD and USB cables on eBay have mostly free shipping. The servo connector is for crimping on the other side of the microUSB cable so you can easily connect it to ESC output. Or you can just cut the one on the ESC and solder the cables together. Its just my personal preference, do it any way you like. B-).

What's an example of this USB A-miniUSB cable tehPajka speaks of? (and why servo connectors needed in tehPajka's build)?

Also, I want to use this with 6 rechargeable AA batteries but can't seem to find a battery holder for 6 AA's on Hobby King (only 4 AAs). Any suggestions on how to achieve this? I'm trying to order all parts at the same time to save on shipping fees.

Thanks!

F, it hast to be microUSB, not miniUSB. If you write "USB A micro USB cable" to google image search. you will see what that cable looks like :-) But any cable with microUSB will suffice, the other connector is not important. You can buy servo connectors here, PRODUCT ID: AM-1021Bx10. I powered mine with 2S 5800mAh LiPo, I didnt want to use AAs. But if you want to try it, they are selling 6AA holders on eBay for 2 USD.

Will this BEC work for my Gopro 3 to power it up through an adaptor?

Simply Yes

Can I use this to power a RaspberryPi? The RPi requires only ~700mA at 5v..I'm a little worried as this product states 5V/3A.. Also, while I understand that the RPi has a 5v rail with which I can power it, I would like to know whether there is an easy way to convert this output into a micro usb
 tehPajka 192 points
Yes you can, I have tried it. Dont worry about the 3A, it is maximum current output of the BEC, it will in no way force the 3A to the RPi :-) RPi will take its 700mA and thats that. Connecting BEC to microUSB is quite easy, you will need USB A - microUSB cable and servo connectors sold here. Cut away the USB A connectors, there will be 4 wires, find the red (VCC) and black (GND) and crimp the opposite servo connector to coresponding red and black wires on the BEC.

Small, lightweight UBEC. I use it for losi 1 / 24 micro rock crawler, because lipo 7,4 v much for him, and original HiNH 4.8v expensive. This inexpensive but very good solution:)
