The other thing to remember is that a big battery will take longer to charge than a smaller one. Fine if you need the extra grunt, but if you don't why haul it?

I run most of my smaller stuff on 800mAh batteries which will charge up overnight on a wall wart. Bigger stuff gets bigger batteries and I have to think harder about charging, which makes my brain hurt[:@]

Just my $0.02 worth!
