I have been trying out AA sized lithium polymer batteries. They have the charge control and voltage regulation built into each battery a solid 1.5V out until it's flat. One downside I have noticed is that if you have one flat battery and 3 good ones in series it will try to force the current though the dead cell and heat it up. This can happen with any battery chemistry though.
A colleague mentioned a particular brand of these which he thought were better (this is his research area, so I trust him), but I forget the brand name. When I find out again, I will compare them with the Tenavolts brand I'm testing now.

The EBL rechargeable batteries hold the 1.5 voltage across their drain, however then they drop off sharply causing a shutdown when they are at the end of the discharge cycle. Not really an issue for me as I use the Rex and Jeff's backpack so I can save often on projects. Just some of the tradeoffs I have noticed when using rechargeable batteries. -Allan Zieser
