For those of you contemplating using lithium power tool batteries to power your electronics, Home Depot has a deal going on right now for two 18 volt 4.0 amp hour batteries, charger, and bag for $99. I provided the links to the deal and to the $40 Seelite adapter you'll need. People have been reporting getting all day run times using power tool batteries and allegedly have better pictures.

Home Depot Rigid 18V $99 Deal

Seelite Rigid 18V Adapter

It’s a good price for tools, doesn’t make much sense for graphs (if the graph can even accept 18v in the first place). If your graphs small and pulling 1.5 amps and the LS/AT is pulling 1.5 amps, you’ll only get an hour and half max per battery.
