+1 I was just going to point that out, although I was under the impression that LFP (that's the short name for LiFePo4) batteries could do 80% DOD. Either way, it's a big deal because of the additional storage. bp On 1/3/2024 5:02 PM, Peter Kranz via AF wrote: Something to think about is

Something to think about is that LiFePO4 is good to 100% DOD, whereas we should all be keeping lead-acids above 50% DOD if we want lifespan.. So 460Ah lifepo4 = 920Ah lead-acid in my mind.. Peter Kranz www.UnwiredLtd.com Desk: 510-868-1614 x100 Mobile: 510-207- pkr...@unwiredltd.com

Of course the algorithms will be showing us all ads for LiFePO4 batts now. I got one the other day for this one: https://www.epochbatteries.com/products/12v-460ah-lifepo4-battery-ip67-heate d-bluetooth-victron-comms 12V 460Ah in an 8D size. What some people call a "truck battery". That's a lot

Yes you poll each unit. Each battery in the string has a Battery ID set by dip switches. If you have a compatible inverter/charger it polls each battery to pull data points of interest. Take a look at this battery, it supports CANBUS, RS-485, and chaining batteries with battery ID's set by dip

It's kind of an awkward situation. Suppose you have 4 batteries total, each with their own internal BMS. Do you want to monitor each battery? Maybe. My first impression is no. But perhaps knowing that battery #3 has a problem would be a good thing, like your car telling you all the tires are

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

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

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

How many total routers do you have in the OSPF area? We ran into a similar issue and ended up having to segregate portions of our network into separate OSPF Areas to bring stability back. There's a wall you'll hit when topology changes occur and the routers can't keep up with route updates,
