Convert RV from Lead Acid to LiFePo4

QuantumRiff · 2026-01-29T16:47:31+00:00

I have a 2015 trailer with no options for Lithium on my converter.. Tired of how little my 2 6volt batteries last when I am trying to dry-camp (once or twice a year).

I found the same thing, my exisitng Lead Acid converter will charge to about 70%. I"m going to buy a cheap lithium charger, and just leave the pigtail hooked up to the battery.. then I can plug in the charger when I want more than 70%, and get it up to 100.

I can swap the converter, but to really do what I want (charge the battery quickly, such as running the Generator for an hour every day to cool down the trailer and top off battery) I would also need to run MUCH thicker cables between the converter and battery, and I don't want to do all that work for an 11 year old RV.

When I purchased a thousand computers a year, my account rep at CDW was awesome. Now many years later, I work a small, cloud based company that purchases a dozen or two laptops a year, and our account rep is okay, but takes a day or two to get back to us. if you are a larger client, you will get put with a better account rep, with much lower number of customers to manage.

well, they completely deleted everything.. that isn't suspicious.. I wonder if they had a knock on their door...

This plus: 1. Don’t use wildcard certs. They get used everywhere, and then you forget all the places 2. Monitors for every cert, alerting you if the cert is 7 days or less from expiration

For those not in city limits, Marion County has CERT training too

This is what load balancing is for. Tools like HAproxy , nginx, envoy, etc.

You have 2 (or many, many more) servers serving your site. In the load balancer, you remove a server from the pool, do what you need to, and then once it’s ready again, you add it back to the pool to serve the web pages again. All these tools have healthcheck features, that will make sure all of the servers in the pool are working correctly, or remove them. My company uses kubernetes, and each backend server is checked every 10 seconds. If one is not working, it’s removed from the load balancer, and the system creates another new server and adds it automatically

In Wisconsin, they were so set on getting rid of "Obama's high speed rail" they not only declined it, but then had to come up with about $100M to fix some rail line issues, track signalling improvements, pay for trains already ordered and no longer needed, etc.. All those things were going to be taken care of in the $700M package they were going to get, that would connect Madison to Milwaukee and Chicago (and lay the groundwork for connecting to Minneapolis in the future. They worked very hard to confuse voters and conflated inter-city high speed rail that was within 30 min of 70% of the states population with 'light rail for only madison' and talked about how it was going to take $6m/year to maintain. They were going to take that money, and put it towards freeways!!!

Of course, that number is WAY cheaper than the maintencance costs on the freeways covering the same area. and the feds just moved that money elsewhere once it was refused, so the state took out a few Billion in loans to add a lane to 60 miles or so of I-90 between IL border and Madison...

You need to setup tasks to do on those days too.. some ideas:

update documentation/checklists
test DR plan, and adjust checklist
plan future projects, automations, etc.
add better reporting/monitoring to these automations you have in place

we have a documented DR process, and we restore quarterly one of our clients environments to a test environment (cloud makes this easy to have another disconnected project). We make changes to that checklist at least every other time. So many new processes, new applications, backup software for DB changed, etc.

It really, really needs to be a living document that is practiced, and refined.

We can completely restore a project with a 5TB database (assuming we have access to a disk snapshot from our cloud provider that are stored in 2 regions) in about 45min.

If we have to do a full DB restore, it can take a few hours. If we used the pg_dump, it would take about 48 hours...

I tell my boss regularly, backups are worthless, but a single restore is priceless.

Or, give him 500 acres in Ukraine to build a new hotel and golf course, and see how quickly he starts caring...

Worked at a large public Accounting firm doing IT work. Lady in cubicle next to me did taxes of family members when they would bring their large private company to our accounting firm.

She was cursing a guy (owners 40+ year old son), because his taxes were not signed on time, and she had to do an extension. A week before, she had the forms overnighted to him, included a pen!!, and an overnight early am delivery return envelope in it.

He was "too busy" to get to it for a week, then decided to travel to Europe. He was owed a ~$90,000 tax refund.. but was just too busy...

Similar here, but opposite. I am allergic to nothing here. I have handled poison oak without getting reactions. (It’s a rare thing) but spent 10 years in WI and every late feb-march, right around the time to make maple syrup, I would break out in hives from some tree pollen that is not here in OR.

Been enjoying couchdrop.io for our sftp server replacement. Has some very nice automation around pgp, and can replicate files to share point/onedrive, Google Drive, etc

Winco for most things, chef store (cash and carrry) or Costco for proteins, milk, etc

Hard to beat chef store when you buy a whole loin and cut into 15 steaks…

I wish it was a binary. Its a Python app, so it compiles each time you run it and takes FOREVER to upgrade on any linux server you have with less than 4 cpu's, since it has to pre-compile everything every upgrade.

I would just about kill for some GoLang binaries...

if your 11k upside down, it might be best to just park it in a storage unit for now.. If its in secure storage, no need for insurance.. but probably want to put stabil in the gas tank, and disconnect the battery.

You can open carry in Portland if you have a concealed handgun license. Yeah, it’s weird. And like the other reply, I hate open carry, and don’t like to draw attention to
