Just out of interest, does anyone run batteries (via fuses) directly into
cat5 instead of converting back to AC just to run standard 48v PoE up the
tower?

I'm pasting Gino's link to the right thread.

Can we get some links to these batteries that work well?
Gino,
Got a link to the DC block connectors you were talking about?

Hi,

We run two 4 gauge power wires out the front of the case, connect the positive to a 60A fuse, and then to the batteries.

We are using AGM type (same thing used in UPS systems) big batteries (a little bigger than a car battery, but each battery is 110 pounds). We wire them in series (to get 24VDC).

This setup has only been installed for 12-18 months at various locations, so I don't have an estimate on battery life.

You got any pics of this or similar Travis....anyone?

Travis,
What APC do you use and what batteries are added? What do you draw and what is th run time? Do you know how many times the one with the most cycles has been drawn down? How long do the batteries last?

Brian

You can't use just 1 battery. The APC units want to see 24vdc, so you need two batteries running in series.

It works perfectly, as I have 20+ remote locations running off two gel type batteries. Make sure you install some type of a fuse on the positive side of the connection.

I believe I remember some discussion on this list on connecting an external battery to an APC UPS. I'm in the middle of doing it right now and am having problems. The UPS just beep continuously with the 'bad battery' light on. I'm using a Lifeline deep cycle battery. Any ideas?
