Wow, I'm amazed how much power you guy's go through! Do you use your batteries down to their "empty" voltage or just half way??

.. since having an amp meter on my setup I've been able to much more accurately track my usage and realised just how little power is being used much of the time.
I guess if you have 2 scopes 3 camera's 2 laptops external hd's, unbalanced mount, etc.... you're going to chew lots, but gez, how do you find the time to setup and dismantle all that power hungry equipment?!
