Aaton XTR Prod - Batteries

Recommended Posts

I'll be using an Aaton XTR Prod for a feature this summer. The camera has 3 batteries, of which only one is in usable condition. All manage to run the camera ok but if i start using the video assist they all drain quite quick. The user manual says all power sources that are 12V are ok. I would like to replace those ones and output a d-tap somewhere so i could power additional accessories. Any ideas on a solution? 

I could contact a service center and ask them about the power requirements of the camera but i don't know who deals with these cameras recently. Is it ok to use some V-Lock batteries somehow?

thanks

I use a v mount plate with a d tap to 12v limiter to XLR plug. a 12v limiter is necessary, since modern V mounts actually run at like 16.8v when fully charged, which can make the camera go pop. I got my adapter from indiprotools.com

you can get batteries recelled or get new batteries from Ablecine in LA btw

I run the NP1 solution, which is super easy to deal with. They make dozens of varying NP1 to 4 pin XLR that you can very easily connect to anywhere on your camera. They also made adaptors which were for the Aaton which work great on ALL the cameras BUT the Xtera. I use the batteries as stock 15.6v and they work fine. The power regulators in the camera which convert everything to 5v are good for upwards of 30v before they fail. Sadly nobody appears to make 12v battery solutions anymore, they're all around 14 - 16v.

it is easy to find 12v nimh batteries made for other purposes. for example 12v rc car batteries are easy to find. attaching a 4pin xlr to that would be a 5 min job and it is also possible to create a adapter cable so that you would have for example a tamiya to xlr adapter cable and couple of unmodified tamiya batteries you can use with it. the lower quality batteries self discharge relatively quickly and are not very pretty but otherwise should work fine. 

a v-lock plate with a voltage regulator should also work

Thanks to all of you 😉

I wonder about the V-Mount /15 - 16v/ batteries, would there be a problem with keeping the frame rate consistent if it has more than 13-14V?

Anyone had some experience?

I've ran an XTR+ off of regular anton bauer dionics with no issue.

If you are concerned with over voltage and cannot build or buy a 12v regulator, you can elect to not charge the batteries fully and check their output with a multimeter before use. 

As stated before most Lithium Ion batteries will be in the 15-16v range when fully charged, a battery at 75% will be in the 14.X range 

A higher voltage shouldn't have an effect on the running frame rate of the camera, the only risk it would pose would be to the components on the boards and video tap.

Again, my batteries are around 15v and the camera works fine. The voltage regulators are designed to reduce the voltage regulators inside the camera, are designed to reduce the voltage down to 5v which is what the camera runs on. These are not "analog" cameras, they're computer controlled motors, so voltage is regulated.

Sorry late to this...

I made a battery adapter to use Ryobi 18V Li batteries on my XTRProd.

I used a Aaton battery and fabricated up a Ryobi flashlight which mated to the Aaton battery.

I put a DC to DC regulator in to clamp the 18V battery down to 16V to feed the camera.

I also put a 12V regulator on it and a D-Tap for accessories like a monitor or Micro-Force.

I am building one for someone now based on a smaller Milwauke 12V battery.
