Power source for Downlink and Gimble servo's

[ssozonoff]

Hi All,

How are people powering the electronics on their AP mounts?

Should I be using 1 Lipo for powering both the wireless downlink and my Rx + Pan and Tilt servo's or use a seperate pack?

I realize that the downlink will use more current than the Rx and Servos so that pack would probably need to be of a good size.

What size packs are you using?

If I get a single pack and only want to use one voltage regulator then in my case I would need to run at 5v since this is the max. my downlink transmitter can handle.
I would however not mind running my Servo's at a higher voltage.

So, do I run two voltage regualtors in parallel of the same pack and use one to power the downlink at 5v and one to power the servo's at 5.8-6v?

Thanks,
Serge

I am also interested in this.

I know there are some of you out there running 6V on your camera mount servos, does your Rx handle 6v also, or like Serge asked are you splitting it and running 2 voltages?

5 and 6v?

I run two BEC's. One is a UBEC HV for the chopper RX and servos and the other is a smaller 6v BEC for the camera, downlink, ZLOG, Vizion, etc.

I was not clear on my part.

I run 2 BEC's also. One for the heli, and one for the camera mount. We'll ignore the heli one for now.


On my camera mount, I have the following:

5V BEC
Rx
BWAV downlink Tx
2 servos for pan/tilt
flysoft switch

Can I just make this camera mount BEC be a 6V one?

I *thought* RX's only took 5 V in. Can they handle 6V also, I guess they should be able to since the servos can run at 6V.

Any issues with the flysoft getting 6Volts?

Thanks

RX's can handle 6v all day long.... I used to run 5 cell nicad packs back in the day. as for the flysoft I'm not sure but I suspect 6v would be fine

Thanks,

So in any case you end up with two power regulators and one or two battery pakcs. I have for the moment opted to go the 1 pack 2 regulator route as well.

I am using a proper Bec (linear not switched in this case since my Lipo's are 7.4v) for the Rx+servos and I am using a small switched (linear could be used here two) supply from Dimensional Engineering for the downlink + optionally camera (it can handle 1 Amp which should be fine for a 500mW transmitter I would think) and it weighs nothing (5grams).

I know that the BW transmitter (at least the 500mW unit) will not live long with more than 5v. It already has enough trouble at 5v :bomb:

I'm just using small 2s LiPos and a couple of extra align BECs I had laying around.
