Conservatism and institutional momentum, well said. Same here. One issue apparently is can't charge them below 0 degrees C. But I'm seeing ads claiming internal heaters and temperature controls. Can't speak from experience, I just put in a bunch more AGMs.
I also see from specs a lot about Bluetooth. I'm used to lots of controls and stats via web and SNMP from some of the high end charge controllers like Alpha, Eltek, ICT. How do you access the battery control module at a remote site if it's Bluetooth? Or is that just for initial commissioning? ---- Original Message ---- From: dmmoff...@gmail.com Sent: 1/3/2024 1:25:16 PM To: "'AnimalFarm Microwave Users Group'" <af@af.afmug.com> Subject: Re: [AFMUG] -48v power plant We're still building with VRLA batteries...but that's just the combination of conservatism and institutional momentum. I'd look seriously at LiFePo4. For compatibility with existing rectifiers you'd look for battery packs with a charge controller and management built in. You can then disable the temperature comp, equalization, or whatever other smart/fancy stuff the rectifier would do and just let it serve as a power supply and distribution device. There's a devil on my shoulder telling me that with Lithium drop in replacements with integrated controllers I can eliminate the rectifier and just get a beefy 48V power supply and a PDU. But there's that institutional momentum thing again. -Adam -----Original Message----- From: AF <af-boun...@af.afmug.com> On Behalf Of Mark - Myakka Technologies Sent: Wednesday, January 03, 2024 1:45 PM To: AnimalFarm Microwave Users Group <af@af.afmug.com> Subject: [AFMUG] -48v power plant Happy New Year I need to build a new -48v power plant. Last one I did was about 7 years ago. I know things have changed. Any recommendations on manufacturers? What are thoughts about LiFePO batteries vs the standard telcomm batteries? -- Thanks, Mark mailto:m...@mailmt.com Myakka Communications www.Myakka.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
