A useful comparison test of rechargeable batteries for flashguns conducted on POTN here: http://photography-on-the.net/forum/showthread.php?t=677074
Don't know if it's the same with enelopps but I have Ansmann Max-e's - lot's of them in xbox & wii controllers, two flashguns plus spare batteries, remote control hansets etc.
They are brilliant, but don't be tempted to put them in a normal charger, they get very hot. Get a proper charger for them.
I think the technoline bc900 is probably the best one I've yet seen but it is not cheap at £30 or £40 (can't remember just at the moment). 4 seperate channels with different charge modes and LCD display for each battery so you know what it is doing.
but tbh I never go anywhere serious without a set of Energizer Lithium in reserve! There's a pack in my bag at all times - just in case.
