My point of

"Many golf carts use say a 8V battery(ies)..."

Is that there are different batteries for golfcarts - sure there are 6 and 8 and even some 12V.. But I don't think I have ever seen a Car battery that was not 12, etc..

But sure batteries designed for solar power storage would prob be ideal..

To reduce power consumption and extend battery life, I removed the HD and CDRON drives and run pfSense on a USB flash drive.
Also using a USB extension cable to isolate the flash drive from the PC heat source.  It stays much cooler that way.
Thanks for the line speed notes.
Excellent optimization and heat reduction ideas. Poor laptop has no innards left...

Picked up two of these APC Back-UPS 550 for $50 each ("on sale") a few years ago at a local BB.

http://www.apc.com/shop/us/en/products/APC-Back-UPS-BE550G-NEW-MODEL-AVAILABLE-BE600M1-/P-BE550G

One of them will run the ONT for about an hour.  Maybe a little less.  It's been a couple years since we've had a power outage last long enough to deplete it.

The other will run a NUC w/USB attached HD, 8 port switch, WiFi AP, networked TV tuner (Silicon Dust), and antenna pre amp, for about 35 minutes if I recall.  So once an outage reaches the 10 or 15 minute mark I shutdown the NUC and TV tuner to extend the capacity for the network.

The pfSense notebook is pretty old (Dell Inspiron 5100 P4).  So it's no power miser for sure.  Think it's battery lasts somewhere in the 30-60 minutes range.

Have brainstormed the idea of an inverter connected to a bank of car batteries being supplied by a charger.  But the maintenance, hazards, etc. is just not worth it.

A consumer product built to purpose is more appealing and practical by the time all is said and done.

Solid! Thanks for the response NYOB! $50 each sounds like a steal (then again i'm always trying to be cheap and cut costs whenever I can). The run time sounds pretty ideal as well, unless you are looking at a more prolonged power outage but that rarely happens - and at least the notebook doesn't hog too much power.

It would be cool to give your idea shot at some point, but you're right the hazards are glaring red flags...although think of the possibilities if you could actually pull it off?

Notebook pfSense and UPS supported network is great.  Just survived a 40 minute power outage.

Hey NOYB, quick question about your UPS. I was just wondering what model you have and how much you got it for? I was recently looking into buying the APC Back-UPS pro1500VA and I wanted to know if anyone had some firsthand experience with it. Just to get a second opinion (in addition to the reviews).

The APC1500 is all I run. I even purchased the external battery for two of them for extralong life.  As mentioned replacement batteries are easy to locate for them. I usually hit batteries plus up for them. If you check out the show your pfsense thread I just posted a pic of 4 of them lined up. Totally recommend them
