yea, so, I am wondering, I am probably draining some decent power here...

Mac Pro w/ 3HDs
4 LCD's
Cable Modem/Router
Backup 2-HD RAID Kit
100Watt Lamp

There are some other smaller things, but those will be the major power suckers...

So, you are recommending a 20A on the lead from the UPS to the battery? On the positive terminal, right?

If I run a couple in parallel, would you put one on each positive lead?
