(Part - 2) So was it worth it after all of this? Yes because I learned a lot about these batteries. What makes a good vs bad one. What component vendors are high quality vs low quality. I believe one can save a good 1/3 of the price implementing a DIY battery vs an off the shelf one if you...

If you get a chance to hear an interview with the producer do so. The one I heard was interesting because the intent of the production was to promote green energy over dirty fossil energy and the more they got into it, well facts told a bit different view. Basically green energy isn’t a...

Why 12V….because solar parts are everywhere! From Walmart, HD, Lowe’s, Autozone, Oriel’s, NAPA, Harbor Freight, Tractor Supply, Bass Pro,…. 12V systems in a disaster situation can help more people. Solar arrays based off 12v nominal panels even configured for other voltages (24, 36, 48,…)...

Sound effects on an EV,...really? It’s like being being Vegan and grilling simulated meat.

Got to love today’s “environmentalist” who support maximizing human impacts upon on nature in the name of “green energy“. It’s a desert or vacant land so it’s ok to strip the land clean and keep it sterile. There’s nothing out there. Wrong! There is life there, you’re just not looking for it...

Interesting video but simplistic logically. I’m not going to address the multiple fat shaming references but agree with you that it’s a symptom of a complacent society similar to that of the Romain empire at the time of its collapse. Yes the citizens of advanced societies today have it very...

If I read and understand your question, we’re talking about a 2ft run per cable. The delta in them is insignificant. You’ll have more resistance/voltage loses at the terminals/lugs. If you’re super concerned about adding any minor loss due to cable length, the go up one diameter size on the...

Boy you got a good one! Happy wife, Happy Life! Mine would just ask “What‘s a Lithium? How much did you pay for that thing? Do we really need it?

Science isn’t the problem. Tribalism bias that’s the problem. Tribalism bias presents itself everywhere, even on this posting. This bias causes people to discredit and dehumanize anyone / everything that is perceived not to be in lock step with the current collective thought of their tribe...

I have this SD-200A Square D Generator Interlock Kit installed on my house panel and assuming you’ve followed the direction, this is a manual transfer switch that physically locks out the main power and allows a back feed of power through a double pull breaker into the house. With the...

You kinda answered your own question. You get what you pay for….typically. The vendors who have done and post test results will often cost more than those vendors who claim their products are rated/spec’ed. Makes me think about those airplane parts that came from a vendor who falsified the...

Here’s a couple more pictures illustrating what I need to address in assembly my battery bank. The first two pictures illustrate the leaning problems. Milling bevels into the busbars requires to many different angles, makes the busbars less usable in future battery builds, and just requires...

Talk about a blast from the past, I found an old Popular Science magazine October 1975 while doing some storage container cleaning/purging. I’ve attached some photos below of these articles that I thought I’d share with the forum. Talk about bringing back a lot of fond memories. For those who...

I need more kool-aid or “re-education camp time” I guess in order to ignore the fact that cost of power generation is just one factor of many factors that need to be considered in the selection/decision process. So nice that someone claims 29% lower…blah blah blah so what. How did they...

If you live rural/remote and you can afford one then most definitely you should own a tractor. I’d recommend one that has the quick connection front for dirt buckets, blades, fork to load/unload palletized goods, must have 3pt rear attachment option, PTO, and have an extra hydraulic controller...

Here’s an example of a “better” green energy product. https://www.bluesky-energy.eu/en/saltwater_battery/ Yes, it’s not a high energy charge/discharge battery type but virtually 100% recyclable, not a toxic stew for the environment, and rather safe compared to other battery chemistry. I think...

fadrd- you stated ”...And I’ve also read that some have been successful at straightening their angled grubscrews by force (presumably after they’ve been fixed in place with Loctite)....” I my opinion/recommendation: DO NOT ATTEMPT TO BEND/STRAIGHTEN THE STUDS ONCE ATTACHED TO THE ALUMINUM...

Sodium sulfur batteries are not DIY friendly. Clearly not a battery I’d bring home. There might be new designs out there but the ones I’m familiar with are high temperature batteries. The first time I saw these batteries date back to the 80’s when I was in engineering training. My on the job...

Warning- Don’t purchase too small of generator. Leave yourself some “headroom” (additional power capacity) when selecting the size of generator. Over stressing the generator can cause all sorts of problems from under voltage too over voltage issues, too voltage glitches/spikes as loads come...

My DIY LiFePO4 Battery Build Experience - Part 1 Summary: Was is worth it…yes from a learning experience but no because I thought I only would have to assemble and go. Who knew I had to become a battery manufacture? I just wanted affordable high capacity batteries...

Lead forklift batteries have been the way to go for years. These batteries are made with more lead, thicker plates, … to way out last the typical deep cell. That’s why so many stationary off grid buy refurbished ones but start with a new one and treat it well, they last for years. These...

Once again California who the rest of the USA is supposed to look up to is having grid supply issues. They now are asking EV owners to adjust their charging times. Others to adjust their power consumption too. California has implemented a Flex Alert program to assist its users as to when they...

Seems like there’s two threads going here. 1) Power grid talk and 2) The media. Would be nice to have the media discussion/comments put on its own thread. I’d like to hear more how other areas are address their power supply needs. Here in Nevada the in state power generators that were coal...

Would you recommend solar to your friends? A: Depends upon the situation. Insufficient Data: Solar is just one of many possible solutions to an energy need. One must be able to define the need, specify the location the power is needed, specify the environment the energy will be generated and...

America Is a Republic, Not a Democracy Well really a little of both. Here’s some thoughts on this. https://constitutionus.com/democracy/is-the-united-states-a-republic/ https://www.intellectualtakeout.org/article/us-democratic-constitutional-republic-and-yes-it-matters/...

39 years of marriage for us. She‘s the social butterfly that has the people skills. I guess I’m the fly swatted that brings in the cold hard facts of reality.

Boy can I relate! My wife is very social so lots of get togethers with me in tow. I couldn’t count the number of times at these parties when someone would ask what I did for a living. Tell them I’m a Systems Engineer and watch their eyes glaze over. Soon they need to go do something...

If you’re concerned about EMP type events, purchasing spare electronics and wrap them up in their packaging in foil. Then wrap them with insulation aka paper. Then wrap again in foil and paper/insulator material. Place wrapped electronics in a tightly sealed metal container. Basically you’re...

You can try Liquid Tin. Coats as fast as the liquid touches copper. Here’s a before and after pictures of my DIY bus bars.

$150 Kirkland battery vs $799 on sale Battle Born Battery is basically a wash. https://battlebornbatteries.com/product/12v-lifepo4-deep-cycle-battery/ You will need to replace the Kirkland battery at least three to four times in the next 10 years while the Battle Born Battery will most likely...
