Well I'm getting 2 to 3 hours on a battery, if you have several sets of battery's and don't mind charging them then you should be fine. I have my P16 to fall back on if need be but mostly just take my P10 with my when I go out for a while and always take a extra battery. As far as the new switch Dave's making so it will take the AW battery's I guess we'll have to see, but I'm sure it will only improve or Dave wouldn't make it!!!
