10 AA battery holder/ Rule Bilge Pump

The lithium ion packs are starting to come down in price and will be the next hot set up.There is a 6.4amp hr. LiFePo plastic cased battery that weighs less than 1.5 lbs!

That's very interesting, Mark. Thanks. I had never heard of them until now. Now, if only the price would take a dive. One of my co-workers remarked that he tought, for LiFePo batteries, you have to be careful not to overcharge, that is, more than 80 percent.

Al Lasher on University Ave, in Berkeley, have the cradles your looking for, at around $2 a pop. they also have really cheap rechargeable batteries for sale. EXTREMELY helpful mom n pop store. Anything you find at RadioShack youll find here at half the price.
10aa's wont run the 360gph bilge pump for very long at all. Like SBD says, use a 6v brick. at 12v you have a "water feature" on the back of your yak, and may run out on a long day of fishing, while the 6v brick has almost double the amp hours.
Most of the bait types we commonly use (shiners, smelt, mud suckers, gobis, bullheads)dont need water changes during a day of fishing, aeration is plenty, and that cuts down on weight and complications. Chovies, herring and possibly sardines will most likely need modest water changes.

Thanks for the advice. I'm going to go with the 6v battery. The season is here and I need to finish this project.
