Hi all,
I'm a glaciologist that monitors glaciers using automated cameras. I'm now at an outpost in the Yukon trying to upgrade one of our systems to use a Canon 6D. For the older Canon cameras I've used, to connect the camera to the system's battery I just made a dummy battery by opening a standard Canon battery, removing the internal battery cells and electronics and wiring the battery contacts directly to the external system battery. However, after doing that for the 6D, on power-up I get a menu saying "Cannot communicate with battery. Use this battery?" and if I don't put OK, the camera won't do anything. This request, messes completely the operation of our camera controlling system, which assumes the camera will be ready to shoot soon after power-up.
I installed ML in the hope that this battery-check feature would be disabled, but after trying it, I see that's not the case.
Can this feature be disabled using ML? Is there a workaround for this problem?

I know that perhaps the best option is to use a Canon dc coupler (a.k.a. dummy battery) or an alternative one. But it is unclear to me if these devices just bypass the input voltage to the camera or have a voltage regulator inside that requires a higher voltage, in which case it won't work either (as the system battery is a very large 7.4v Li-Ion battery pack). Anyway, it is very unlikely I can get one of those dummy batteries here before we leave. So I would really appreciate any advice to disable this feature using ML if that is at all possible.

Thanks!
