Quick Question: To hook up RRM follow-focus to Movi battery...

This guy, which I use quite a lot

Using it on an fStop receiver tonight in fact.

 

The P Tap cable is pretty great as a universal adapter too. Ive powered my TV Logic, Teradek, and Digital Bartech off this combo.

as long as your stuff has p tap power cables.

 

Be aware that not all two pin lemo inputs have the same polarity. I believe the Teradek is opposite to RedRock and fStop.

 

Hey guys,

do you hook up these accessories to the same battery that powers the Movi or did you mount on additional battery in the cage? Also, how long do these movi batteries power other accessories? Do you think it would be possible to power a Blackamgic 4k camera?

I'm desperate to find a solution to power up my follow focus and camera within the cage.

Thanks!

 

Hi Phillip,

sorry, i´m on a shoot all the time, that´s why i could´t answer you in the Blackmagic-Thread.
I would power the ff with an y-splitter cable and the Freefly BEC to Lemo cable from th main MōVI battery.
I used to power the BMCC most of the time with the internal battery only. Just plugging in the charger all the time the rig was set on rest.
That worked fine for me- in some special cases i also used a separate lipo-battery (4S/2500 maH) with a barrel-connector cable to buffer the internal battery. With this setup i was able to run the BMCC for about 3 hours. Since i´m on the Epic route now, i use the side v-mount to power the ff, cinetape and other stuff on the gimbal and even built an adapter to power the M 10 via P-Tap in case all the MōVI batteries quit.

Best,

Wolf

 

Thanks, Wolf! Did you just use another Mōvi Lipo to power the camera or another brand? Also, did you build in any safety circuitry? I keep reading that you have to build in some sort of monitor to make sure the battery isn't drained completely?

Last but not least: how did you mount the additional lip on the rig without having to re-balance every time you change out the battery?

Thanks!

Philipp

 

Hi,

I used the standard Mōvi battery and velcroed it to the bottom of the cam ( i always hung the BMCC). So i had a fixed position,
not changing the balance.

I put a standard, cheap lipo checker on the balancer-plug and was able to check voltage constantly. To buy at Amazon or any rc-store. Most
They mostly have an undervoltage warning, too.

Best,

Wolf
