Do you think something like this:

could be configured to run the AD1K? If so, how?
I think I linked to the above in another thread. In poking around a bit, it seems there are better price / performance options.
Any lithium ion battery that supports the AD1K's specs will do, namely: 12v - 15v voltage, 1.3A or greater sustained current draw (or ~16W power), and the capacity you need to achieve your desired run-times should do the trick. How long do you want to power the AD1K at a stretch?
http://laptopupgrade.stores.yahoo.net/unpodvbapa.htmlThis one is rated at 4.9 AH and should give you a theoretical ~3.75 hrs of run-time and weighs about a pound.
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=2650Per the specs, this one's rated at 71 Wh and should give you a theoretical 4.4 hrs of run-time and weighs 1.5 lbs.
http://www.batteryspace.com/index.asp?PageAction=VIEWPROD&ProdID=919Rated at 4 AH, or ~3 hrs run-time, weighs ~.75 lbs.

Cheaper, but longer charge times. Personally, I'd rather spend a few extra bucks for the li-ion packs and faster run-times.
FWIW, a roughly equivalent capacity 12v SLA battery, say 4.5AH and ~3 hrs run-time, weighs in at about 4 lbs.
I believe all of the above will satisfy the AD1K's power requirements. And i'm sure there are other options. Note you may also find better prices than the above.
In all cases, it's simply a matter of wiring the battery to the AD1K 15-pin connector. Since you're using SLAs, you must already have a cable capable of delivering the power from an external battery into the AD1K. I'd just re-use that connector. Then simply wire one of the batteries above with the same connector and pinout as the one you have on your SLAs power supplies right now.
You may want to consider building a Y power cable for the batteries so you can hot-swap them. If you're not comfortable doing this stuff yourself, I bet there's one or more TSers who would help you out. (I'd offer, but my soldering skills are shit.)
All the above options include charger + battery, so you may be able to pick up additional batteries solo at a lower rate since you probably don't need a charger per every battery.
And one final, very important, note: I do not own, nor have I previously owned, an AD1K, so this is all baed on Apogees specs and run-time estimates, not my actual field experience. Hopefully others with first-hand experience will chime in.
