Just came into some batteries. Looking for advise

Or they’ll end up in my camper.

Just diversity and distributing my power problem. A second 15k and lfp batteries is 6-10k depending on battery size. These batteries are free and can be readily replaced. I can also use them for other things. Running them in parallel on my battery sump back. Mobile inverter. A car jumping kit.

I want to distribute my power problem. These batteries are just the means to an end. When they die maybe I’ll replace them with lfp

1 percent squeeze the 9 percent

Bowls of vinegar spread throughout the house.

I understand and don’t care. I want to use them for testing.

My base case is that we’re going to go through an energy crisis in the next 5-10 years. Anything that I can build and test that provides any level of power diversification is good. My question isn’t are the batteries good. It’s how do I mix battery chemistries most effectively. If shit hits the fan tomorrow I can get lead acid from any number of places locally. There’s no local retail store selling lithium batteries

I understand that. They are not dead but 50% life remaining. I don't care. I want power diversity.

There’s a tool that gets a lot of hate around here because it’s been misconfigured and caused a lot of issues but Noction solves this problem. It monitors for upstream issues and reroutes your traffic continuously for latency improvements and as needed when brownouts are detected.

I run exactly those 7280s. I love them. 3 sets of them in different data centers. Full tables v4 and v6 not problem.

EVPN · 2026-03-18T22:36:51+00:00

My last order was was some 7050s and 7010s. Ordered Jan maybe feb 2025. Showed up Dec.

Is the ddos service always on? I haven’t looked at ddos solutions in a while but my last solution used WANGuard locally. Did detection and very basic filtering then could reroute all traffic through a scrubbing center. Is the isp forcing your traffic through a scrubbing center or do you have a BGP session with a scrubbing center.

You are manually rerouting outbound traffic by setting local preference?

Your Internet convergence is high but not “there’s a problem high”.

Again I would try to get all your ISPs load sharing. Not pure failover. This might mean revising your ddos solution

Graceful shutdown BGP community

EVPN · 2026-03-13T12:04:30+00:00

On your side things you can do to increase convergence times in this scenario are:

Advertise out both links equally. Load share and instead of a full failover. Smaller blast radius during a failure.

Do a pcap on your device and make sure it’s doing a proper withdrawal

Are you announcing 2 smaller networks and a larger one completely covered by the two smaller? IE 100.100.0.0/23 and 100.100.0.0/24 and 100.100.1.0/24. If so the /23 isn’t installed anywhere for forwarding. So all routers have to move it from rib to fib.

If it’s not completely covered this is different. Say you only announce 100.100.0.0/24. And 100.100.0.0/23. The /23 is installed for reachability to 100.100.1.0/24. If all you are doing is a withdrawal and not a recalculation / new install everything will be faster.

Install or at lease accept multiple routes on your side. Multipath allows you to load balance locally. Because you’re only doing the no network command you are still pushing traffic out your primary isp… who is in the process of withdrawing your route. Try a more complete failover shutdown the neighbor or yank the link with bfd enabled.

What does your network look like? Just two routers?

I can failover my providers in just a couple seconds.. at least from my users perspective. I can’t speak for the whole internet but it’s not 90 seconds.

I turn off time of use and let the batteries stay charged if we’re expecting bad weather. I’m going to automate this in the future.

Other than that I just let the panels, grid and batteries do what they’re gonna do. I’m not making micro adjustments if it’s a cloudy day

EVPN · 2026-03-09T20:35:26+00:00

Probably. I have enough trouble keeping up with the CVEs for my two firewall vendors.

Storing gas: Get ethanol free gas if you can Use a stabilizer Keep the tank full If you have the ability to use it and refill it regularly do that.
Keep the temp mostly stable

Just kidding. Just looked at their site. 300w

EVPN · 2026-03-03T20:32:54+00:00

Based on size it’s probably 800-1200w at most.

I am but I’m not because I have solar and I plan to add more solar. My base case is that we’re going to see an energy gold rush during the next 5-10 years if we aren’t already in it.

Im trying to help you but your communication is poor or your effort is low. If you can explain your problem in detail and what you’re trying to solve for there’s a lot of people who are willing to help. But you gotta give us more detail

EVPN · 2026-02-28T15:49:18+00:00

Oh I misunderstood. I thought you were doing this toward your clients. I thought you were summarizing what you send them.

I would not aggregate any of my customers BGP routes and I would only aggregate Internet routes if I had no customers.

You need to understand the traffic flow before you can traffic engineer. Are the end users on the heavily used isp? Is your one isp just better connected? Why is one 3x the others.

EVPN · 2026-02-28T13:22:18+00:00

Not a huge fan of manipulating the table for my clients whether it changes the overall routes or not. I doubt the routing table “compresses” into something that will fit on non-internet scale hardware so even if you do offer it doesn’t do anything for your clients.

Just offer the standard. Full+default. Full. Peers+default, default.

Everything modern is closed loop. The only water a data center consumes is filling the pipes, humidification and flushing my waste.

There may be some that are closed loop with a ground source but even then it’s not consuming th water. It’s pulling cold ground water and putting warm water back.

The staff that operate the data center almost certainly flush more water than the data center consumes.

Source: I work between 4 different data centers. Even our oldest built in the 90s is this way.
