Hi,

I bought a Saramonic MixMic for my Canon XC10 (but could be any DSLR-cam) to get XLR inputs.
This device runs on a 9V battery and has no external power outputs. Battery lasts less than 2h30m and I would like to find a way to power it continuosly.

1) I need to build a "fake 9V battery" to put inside and drill a hole (or get 3d printed a copy of the original) in the battery slot door. Fake battery will actoually give me a cable in which to put 9V power. Anybody knows of a fake battery allready done?

2) I can get an external Power Bank (one that works with AC input at the same time possibly). This will give power to the fake battery.

3) I might want to make the cable double so to power my camere too with one battery.

But the ideal solution for me would be to get power out from the canon battery into the Saramonic. This to avoid having bulky add-ons on the camera/saramonic hotshoe. So, ideally, if I plan to use the camera all day long on a stand, I just power the camera and let the camera power the XLR adapter, and in any moment, I can take it handeld and the camera battery will go on powering both. Obviously battery will last less but to me this is the most practical solution. I don't think it will create to many problems as model Canon XC15 works exactly this way (with a dedicated new output plug for a dedicated Canon XLR adapter)

So... any suggestions of getting power OUT from the camera or directly from the battery in the camera handle?

Not sure if this would work but I have a swit S8I50 battery for my ls300 and the battery has a poweroutput which allows me to plugin my videolight meaning the battery simultaniously will power the camera and videolight. Maybe Swit has a similar solution for canon cameras?

Yes. Thank for the link. I didn't know about them.
They have also Canon batteries. Unfortunately not for mine that uses this one. They have a replacement but with no power out. S-8PE6 DV Battery for Canon LP-E6 (http://www.swit.us/sdvbaforcal.html)

In the meanwhile I have started to build the fake battery (I just opened an old rechargable one and I am using it as the case). I still have to figure out about the power FROM the Canon battery but it's a step.

Thanks

Does this one not fit? S-8845 DV Battery with DC Output for Canon BP-945/970G (http://www.swit.us/sbawidcoufor.html)

No. As I wrote above mine is a different series. They have it but with no DC power output
