Hello, I'm looking for an external power solution for my Mix Pre-D for extended shoots. I haven't seen a AC option for it but I might even prefer a DC option if it's cheap enough. The Mix Pre-D says it can handle 10-17v DC. The only time I've seen is the following Hirose 4-pin HR10-7P-4P:

Can I take a 8 AA battery enclosure and connect it to the above? Something like this:

If it's wired correctly, typically for 12 volts. (Eight 1.5v batt.s in series)
There's other options, though not that as cheap. For instance:
http://www.ebay.com/itm/180794710718. You would need to make a custom coax to Hirose cable though. Two would be recommended since they take about 14 hours to fully charge, though one (aprox: 80Whrs)would likely run a MixPre all day and then some.

Your concept works with my SD552. I use 10x in series and 2x in parallel AA NiMH rechargeable batteries. 1.2x10=12 volts + my soldering skill so I thought I saved a lot. Make sure before connecting it to your equipment or putting it in your bag, touch the battery pack if there is any overheating AA.

Sweet. Thanks.

Now i have heard that sound guys generally like to go batteries even when they don't have to (e.g. sit down interview where they're not mobile, in an office with easy access to AC power) to avoid "dirty power", surges, etc. that can screw the audio. Thoughts on that?
 
One of the DIY solutions might be a good idea if you`re handy at putting these things together. I am curious to find out what this HawkWoods adapter costs, as it`s ready to go and uses very affordable large batteries.

Sure, battery operation is often a remedy for "dirty power" or ground loops, or any number of problems you might encounter out in the field. But it is not a "cure-all".

Simple "wall-wart" or "line-lump" AC power adapters typically isolate enough from the power mains that they are usually adequate.

The downside of operating on batteries is that they get depleted, and they are fiddly to re-charge or you need a supply of non-rechargable cells, etc. etc.
