We are currently testing using two 12v 100Ah telecom batteries in series. They are slightly expensive to replace, especially when we will have four (or more) at some sites, most will have two.
I'm using a Meanwell RSD-100B-24 regulator for the Tik RB-493G router right now. Looks like the cutout for the regulator is around 16v from what I can decipher from the datasheet. My test radios (2 Canopy and 2 UBNT) are connected to the battery without regulation. This setup will drain the batteries until they are pretty much dead and buried. I ran them over the weekend and I figured it would stop draining around 10v at worst, it didn't. They ended up around 6v in parallel or 3v per battery. I figure I shaved off some capacity and lifetime of my test batteries with that, hopefully not too much. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Josh Luthman" <j...@imaginenetworksllc.com> To: af@afmug.com Sent: Wednesday, April 8, 2015 1:49:05 PM Subject: Re: [AFMUG] Low Voltage Disconnect First off I'd suggest getting enough batteries that you wouldn't need an LVD. Second, I'd rather see my batteries lose a bit of life and keep the site up then have everything go down saving my batteries. Tertiary/finally, what equipment do you have now? My regulator cuts off at 19v and still provides 24v. I figure the batteries are at 9.5v they're already suuuuper low.
