    Possible increase of heart attack risk after mRNA vaccine.

    I try and go after the information presented rather than the presenter. A lot of people on here take advice from Will P, myself, and others on this forum, who are not licensed master electricians.

    Why don't gas stations have backup generators?

    I carry a small hand syphon pump and tube in my trunk. The way it's designed, it should have almost infinite (figuratively) lift, as long as I keep my thumb over the hole. Being able to pull gas out of a another (or underground) fuel tank may come in handy one day.

    Lishen 270ah-272ah cell group buy.

    Proof! 310AH and 320AH Cells being sold on Alibaba, AliExpress, Amazon and Ebay are not what they say.

    It would appear that way, yes. Edit: If you thought my comment was a personal attack on you (or anyone specifically), it definitely was not.

    Proof! 310AH and 320AH Cells being sold on Alibaba, AliExpress, Amazon and Ebay are not what they say.

    You (everyone) also have to take in to account that people are stupid, and blame sellers for their mistakes all the time. "Woah is me, I got 10k worth of swollen cells, what a bad vendor, blah blah blah..." Meanwhile I can see a power supply set at 8 volts during a top balance in your photo...

    Coffee Maker

    Cowboy coffee! Pot of cold water, add grounds, heat until grounds sink to the bottom of the pot, remove from heat and stir, let sit for 1 minute, pour off top of pot that doesn't have grounds into a cup, enjoy. When I feel fancy, I use a reusable coffee filter and pour the coffee out of the...

    A little advice about Amazon returns and how to cover yourself

    There is a scam run in the exact same way. That's why Amazon said they would "trust you". The general idea is that you buy something, get a return label, Photoshop a different address (located very physically close to an Amazon return center, like a McDonald's up the street), but keep the same...

    Any good Netflix shows?

    If it's still on there "The Heavy Water War" was hands down the best show I've ever seen. It's about the Nazis trying to get Deuterium.

    if a 48V battery can be lethal, how about a 40V panel?

    People are also tazed with 10-100k volts shoved into two metal rods imbedded in their chest. Most of the time they come out fine. Dog shock collars can easily be over 1000v as well. I've hit 240v AC with sweaty salt-water covered hands more times than I can count and, other than being a little...

    Where can I get QUALITY tinned copper buss bars to join cells?

    You should be able to get aluminum bar at pretty much all metal supply shops. I would try AMD Supply LLC and Tri-County Aluminum first.

    Why are 24 volts LiFePO4 batteries a lot more expensive than buying two units of 12 volts version of the same battery brand for same AmpHour capacity?

    I would think that 24 volt batteries would be less expensive than 12 volt ones. It's one case, one set of terminals, one BMS, one set of insulation, one set of wiring & fusing, etc, etc... Also, generally speaking, a higher voltage battery would need a smaller BMS for the same performance as a...

    Global warming is real, why only in USA is there denial ?

    Building 7 is a ridiculously touchy topic, and I've had posts deleted here (and accounts banned on Reddit) for even daring to suggest that it could have been anything other than a fire. I could tell everyone that the earth is flat and that lizard people run the government all day long, but...

    [SOLVED] What size AC breaker, 7A or 10A?

    I have one of those too. I bought it because I thought the display looked really slick, and it most definitely does. The only problem with mine is that it's incredibly inaccurate at lower amperages and is consistently about 5-8% off at higher ones, but that can be corrected for in my head...

    [SOLVED] What size AC breaker, 7A or 10A?

    Can you program your BMS? I have a JBD and can set the over current protection value manually. I would rather have the FETS do most of the work over a relay, they cause fewer issues when "hot" switching loads.

    Some simple, money saving advice, from someone who is finishing up their DIY system.

    You should pitch ElectricianU on YouTube to do some solar videos. He's a licensed master electrician, and I'm sure he would be able to show the full installation done properly.

    Some simple, money saving advice, from someone who is finishing up their DIY system.

    I thought this site got something like 9 million page views a month. I think most of the users probably aren't registered. If you search carefully there's not a lot of questions that haven't been answered, which doesn't leave the need for registration. I would imagine the site pushes a ton of...

    Some simple, money saving advice, from someone who is finishing up their DIY system.

    I think the point is that we all know brands that have been around for over 20 years are probably pretty decent. They're also quite expensive, and a lot of them require advanced knowledge (pulling wire through walls, working on main breaker panels, backfeeding the grid, etc) or an electrician to...

    Downsides to LFP's? Sooo many questions and no bandwidth for videos.

    I see why that is an issue. Even if the power for the coil was pulled directly from the cells, a blown fuse or short on the positive input wire for the contactor would lock it open. Sounds good in theory though.

    Downsides to LFP's? Sooo many questions and no bandwidth for videos.

    Gigavac also makes latching relays. I have, IIRC, a ~250-300amp, GXL14, that was $5 on BH. The only small catch is that you need to build a "switchboard" for it, a little flip-flop circuit does the trick, you need about $2 of components from eBay to make one. I would imagine they have the...

    Solomon islands remote off grid small solar system 12v AC system Help..

    Lots of people use ANL's, best practice is to use a Class T. Bussmann is great. Check eBay for used fuses, they can be had for about 1/4 of the price as new, and fuses either work or don't, so used is fine IMHO. Don't forget a fuse holder, or plan to make your own. That should work fine. Good...

    Offgrid Permit-Free Solar?

    If you really want to be sure you can avoid code, get a small trailer and mount the system in there. Panels could be permanently mounted to a trailer, and extras could be pulled out and set on temporary mounts when needed. Electric code is left up to interpretation a lot of the time, especially...

    Class T fuses between both the battery and SCC as well as battery and inverter. Breakers work, but f*ck DC breakers, and go with a fuse. The only DC circuit breakers I trust are made by Eaton / Bussman, but those are expensive, and I trust fuses more. I would add a main battery disconnect...

    Battery Case Lid Adhesive

    My vote goes to RTV silicone or gasket maker. I use Permatex at work, and it's watertight (when used properly), easy to remove (compared to epoxy), cheap(ish), and simple to work with. I use both of the ones below regularly. Permatex 80050 Clear RTV Silicone Adhesive Sealant, 3 oz...

    Lithium Batteries for Alarm Panel

    @Spliss and @Ampster are also correct, it's not good to float a lithium battery for a long time. I've since modified my setup. I HAD two diodes, both facing opposite directions to drop float voltage. Now I use a single diode to block charging / floating from the UPS itself. I just leave the...

    NOAH'S ARK: Index of LiFePO4 cell manufacturers

    Shenzhen Topband Lithium Battery Co. LTD. They make other stuff as well, but they do seem to actually manufacture their own cells. It appears they make four cell lines, a 100ah, 20ah, 25ah, and a 30ah. In this...

    9000KWh reliance on grid is no good; how to avoid?

    If your roof is already full of panels, and unless you build an additional very large ground mount, as well as add batteries, charge controllers, and associated equipment, the best way to make that work would be to decrease your energy use. Propane and natural gas are both incredibly efficient...

    Is putting PV panels inside a dumb idea?

    My parents just got new windows that are pretty much clear, but block something like 90% or more of the UV light. I would imagine most large buildings probably use clear UV filtering glass as well. I'm sure it's possible to get power, but I'm also pretty confident that the losses will make it...

    CATL 271Ah cell issues.

    This doesn't seem like the same situation though. It's not an employee branching off doing business on the side, it's the owner of a battery business doing side sales, which, depending on how he's doing it, could be illegal (or at least against tax code) in itself.

    Check out the legal definition of "wire fraud", they made the definition loose on purpose so they could smoke anybody they feel like. Mike and his supplier are absolutely 100% guilty of wire fraud, even if it wasn't fully intentional. The posts about people "stealing" make him complicit by...

    Good review on supplier.

    Overkill uses Jiabiada (JBD) BMS's, they aren't actually made by Overkill. You can get them elsewhere for cheaper, but the advantage with OK is that Steve tests them all out before shipping, keeps them in the U.S, and offers a warranty. I have 5 different JBD units (not from ok), and all of...
