75w draw (a monitor), that means that it will run for 2 hours on a 14.4v 150wh battery?
Ish. That 150Wh might be based on a longer discharge period than 2h, and discharging fast usually reduces total usable energy. Also, unless the monitor requires 14.4V DC input, there is going to be some conversion loss to whatever it does need. Finally, if by daisychain you literally mean connecting the output of 1 battery to the charging port of the other, you'll have to account for some more losses; the second law of thermodynamics says you can't draw 150Wh from one place and put all of it in another.

Almost certainly not. Not for long, anyway. Totally discharging a battery is a pretty surefire way to kill it, generally. I think you'll need a bit more capacity if you want it to work more than once for that length of time.
Also, unless the monitor works on 14.4V DC - which it won't - you'll need an inverter. Which won't be 100% efficient, because nothing is.

If I wanted to power something that has a 75w draw (a monitor), that means that it will run for 2 hours on a 14.4v 150wh battery? So if I daisy chain 2 of those batts I should get 4 hours?
