So I'm trying to plan a pretty wild shoot that's going to take place up a big hill away from power. The trouble is it's going to require a remote jib, or robocam. Essentially a servo driven pan and tilt head on the end of a crane. Pretty much everything we have runs on batteries, but not this head. It operates on 14.4VDC and draws about 1.5A. That's what the power supply is rated for so I'm assuming that's it's max draw and it would actually use less than that most of the time. So what are my remote battery options for this thing? I've thought about using a simple computer UPS but the one I have without testing, just doing a bit of math would only last about 15-20 minutes which isn't enough even if I brought 2 or 3. Ideally I'd need about 2 hours of run time. A generator isn't really an option unless it's super small because we've got to carry all the gear up the mountain plus I'd rather not have to deal with the noise. We might have snowmobiles for some transport but still weight is going to be a factor.
Any ideas?
