No lithium batteries. The fuse would be between the DC power supply unit and the separately fused camera loads.

I'm building a control cabinet for my security camera system, it's all 12 volt (Yes, I know I should have gone POE, but the cameras I had purchased were all externally 12 volt powered), so to save money I went with those and ran my relatively small house with 12 gauge wire and cat5e to power...

You would get many more responses if you did that.

I figured out the problem, the high voltage coil is shorted / broken somewhere, which is why I wasn't able to get continuity from that terminal to anywhere else. That also explains why the magnetron stopped working. Thanks for the help guys.

My system is not able to run my HVAC, so I have a cheap window unit that I keep around for when the power goes out in the summer. During the day I put it in the living room, and at night it goes into the bedroom. It doesn't keep the whole house cool, but it keeps it livable. It's not really a...

Xenforo has all kinds of addom spam filters. I can't find the link for it right now, but there's one that you can try out, it's just slider bars that increase or decrease the sensitivity to inappropriate content/spam based on keywords. The one I'm thinking of is specifically called "showcase...

I have mixed emotions about this. Solar is a good thing, but if it involves taking away public hunting land to get it, I'm not a big fan. I wonder how many panels a misplaced .30-30 shot would ruin. Public lands are already shrinking enough as it is, not to mention the deals they have with...

These are just my best guess based on recollection. I also built this system a few years ago, so prices might have changed. -For a 2p4s (8 cell) 12 volt system- -My BMS was about $100 -10 gauge silicone copper wire was about $50 for the amount I needed (I used multiple conductors run in...

While paralleling fuses can be done, it is not usually recommended. I saw this question answered a while back on here, and somebody demonstrated how the failure of a single fuse can create problems with the others.

I would love to see you test fuses and batteries to their failure points.

I know this comment isn't directly on topic, but another option is to heat with gas or wood. Depending on where you live, wood can be free, and it's relatively inexpensive to heat with propane or natural gas (especially considering they cost of inverter and batteries it would need). I'm able to...

I wasn't able to get any continuity between that wire and the frame, although it's entirely possible that that's why the microwave broke in the first place. If that's the high voltage tap, what are the two tabs underneath of the red wires that are connected to an additional coil for? Is there...

I took apart a microwave, because it's not in my nature to throw anything broken away without disassembling it and seeing how it works first. Don't worry, I have absolutely no intention of powering it up. I'm going to use the copper coils for another project instead. Here's the transformer...

I think it's also worth noting that I have added external fans to every one of my UPS's. The transformers in those things get ridiculously hot, and I'm surprised the manufacturer doesn't have a fan in them. The transformer temps were approaching 150° f, I added the fan, and now it hovers around...

Honestly, without having the board in front of me I couldn't tell you much. The most simple way to do it is to add a diode to the charging circuit. Power can come back to the system, but not go into the battery. However, that only works on some UPS's, others will read the battery at 0 volts and...

I've modified a few UPS's to take lithium batteries. I disabled the charging circuit, and charge them externally with a lithium charger.

I also contacted my insurance company directly to ask about my DIY battery bank. I was told by representative that there shouldn't be any coverage issues. He said to read the coverage guide to my plan, and if it is not specifically excluded, it is included. The booklet mentions nothing about...

Getting a refund might be a little tricky, but you can always report the seller for fraudulent listings. Vendors that sell counterfeit items to unsuspecting people make Alibaba look bad, and they actually will occasionally suspend their vendor account.

There's also something to be said about their business philosophy, and not using proprietary parts. Even if you only save 10% in gas, you probably save a bit on maintenance not having to deal with manufacturers, especially if you're a DIY kind of guy. I'm an optimist, and I can only hope that...

You could also use a Bluetooth monitor with a PC app, and login remotely. Google desktop makes it really easy if you have Windows and an Android. I'm sure Apple has something similar. That's how I run my security cameras, I can just check them through Google desktop, rather than setting up a...

Wow, really? That's incredible if true, even 1000 heavy towing miles would be impressive.

I'm pretty sure that's more or less what it started with. I'm pretty sure he's still works as a log truck driver in Canada. Its now to the point where they are bringing their prototypes to auto shows, so a production model can't be TOO far away. They sell / we, merchandise that says something...

That's actually how I found out about them, he really does seem like a stand-up dude too, with good intentions.

No, they're still in the prototyping phase. They look promising though, and they're definitely taking production seriously.

You guys should check out Edison motors. They're a startup based in Canada run by a truck driver, they're building hybrid-electric logging vehicles, that actually seem to be pretty well done. Maybe at some point they'll start working on a smaller truck too. I also like their philosophy, they...

In my opinion, it's very difficult to determine state of charge through voltage alone. 13.6-14.4 = about full 13.2-13.3 = still have some juice left 13-13.1 = going dead Under 13 = about to die That's about as accurate as you can get with a multimeter, especially if testing while under any...

They are completely legitimate in my opinion. I vape, and that's where all of my 18650s come from, I've never got a bad cell from them either.

That's exactly what I thought when I read the article. Maybe a loose connection sparked or heated up, or like you said a relay triggered a spark, that then set off some other type of gas leak. There's no way one of those battery packs blew holes through concrete. A lot of houses in Germany are...

I've also found my instapot to be an incredibly power efficient method of cooking. I can't remember the exact numbers from when I had it plugged into my meter, but if I recall, it used around 500wh total to cook a very large meal.

I've used server rack power supplies to charge batteries before, they take a little bit of modifying, but they can also be put into series to stack the voltage. I paid like 30 bucks for two, used, 12 volt, 80 amp PSU's. You need to solder some wires to get it to turn on, and depending on the...

That definitely looks like a JBD to me. If you go on there AliExpress store, you can get custom ones, with custom specifications made if you buy them in bulk. All of my in use BMSs are JBD, and I have a few Dalys. Never had a single issue with the JBD's. They make a good product.

That looks really good. Clean build. A plastic cover like that is my end goal, The wood was just for prototyping where I need all of the holes and connectors to be. I got to Dremel for Christmas, so now I can cut much more precisely, much better than a sawzall, drill and cutoff wheel.

I've noticed the same thing even over the past couple of years. When I first started building my solar backup, it was pretty much you either buy a very expensive system, or everything is DIY. There weren't very many budget options for charge controllers, inverters, fuses, ect. Now, all that...

That's actually an incredibly realistic and scary situation, I never even considered that. I tend to have bad luck also, so I'm glad that didn't happen.
