Somebody could make a bluetooth to SNMP adapter/converter or something.
Nah, that would be too hard.

There are rack mount LiFePO4 batteries with other options than Bluetooth.
RS232, RS485, and HTTP/SNMP are available with LiFEPO4 batteries built in
BMS systems.. The HTTP/SNMP ones are the hardest to find, pretty much all
support RS232/CANBUS. Some inverter/rectifier shelf vendors now support
RS485 monitoring of your battery strings natively.

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?

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.

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?
