  • Post in thread: What is this battery?

    I was kind of eyeballing that too the other day, but I don't have the time to deal with disassembling packs and rewiring them to anything I could use. But it is a fantastic deal, that's 16¢/Wh.
  • Post in thread: Are this Genuine EVE 304AH Batteries?

    Are they so counterfeit that you are that worried about the quality that you're willing to pay out of pocket to send them back? Ask for a refund and never send them back 💁‍♀️ If they are willing to screw you over, do it right back.

    Fantastic video👍
  • Post in thread: How safe are the Chinese dc breakers?

    Personally I would never ever ever ever use any of these off brands. You can find deals on Nader and Eaton and Schneider out there, why EVER stoop to the low of an off brand piece of safety equipment? Even if you're just using it as a switch and you're not worried about it's interrupt...
  • Post in thread: Santan solar deal

    Very true, but it still sucks to get collection calls every week over it.
  • Post in thread: Looking for 48-52" 200W panels

    It looks like from my precursory research in the past 30 minutes, your best bet is to go with 150 watt panels which tend to be about 42-44 inches long. I haven't seen a single 200 watt panel under 57.5". I have a feeling that unless you somehow find a company that is producing solar panels out...
  • Post in thread: Rewiring my 800Wh Lifepo4

    Setup looks really well built. That's only 800Wh? Take you voltage and multiple your Ah to get your WattHours.
  • Post in thread: Mobile Users Now Have Navigation on Top of Page

    Awesome! That will definitely help, I exclusively browse the forum on my phone and It is definitely a pain to have to go to the bottom of the page every time I want to get to a specific page.
  • Post in thread: Building a Small System for camping off grid.

    But that has an inverter, solar charge controller, AC charger and DC regulated output and it's all built in a box with a handle. You can't really compare a bare battery to a whole unit. Also that's not even a good deal, you can regularly get that for $400-500 on eBay refurb directly from...
  • Post in thread: Server rack battery storage expansion for Ecoflow Delta 2

    I'd put a 20amp breaker between the battery and the EcoFlow unit, but other than that you should have no issues doing this. SOME people do have issues with certain charge controllers on some Power Stations not liking a constant voltage input through their PV input port, but for every thread on...
  • Post in thread: Wanted [NH-USA] local large solar panels or one or more people to do a group buy of a pallet

    I'm always scouting around on FB and Craigslist. 👍
  • Post in thread: How safe are the Chinese dc breakers?

    Yeah I wouldn't use anything with a hole on the top at all that was open like that. Those types of gland connectors are designed to be pointing down. If you absolutely need something to come out of that box on top put at least a 90⁰ connector of the same style in that area instead, rather than...
  • Post in thread: Is it acceptable to use a standard wall switch for a low amperage DC application?

    I didn't specify, but for now these are actually going to be run off of the 12 volt port off of our Bluetti unit at our cabin. But I have a few of those wide range bulbs inside for my 36v battery system, they work great no matter what SOC is.
  • Post in thread: Cheap LFP batteries list. Now with more guts!

    $146 on eBay with their 20% off deal. This one.
  • Post in thread: Is it acceptable to use a standard wall switch for a low amperage DC application?

    It just took me over an hour to upload this video, as I'm out in bumf**ck nowhere at our family cabin-
  • Post in thread: Used Solar Panel Brands?

    I'm a chronic over-researcher when it comes to the things I buy, I spend weeks and weeks looking things up before I commit to purchasing anything. That being said I have NEVER cared how long a warranty is on a product and have never picked one brand over another solely because it had a...
  • Post in thread: Be aware....Just tried to order $2000 worth of batteries from <vendor> and they rejected my C Card. That produced a Fraud alert and cancelled card.

    Same here. If anyone has any extra money kicking around and you need it gone then feel free to use me as your own personal bank.
  • Post in thread: How safe are the Chinese dc breakers?

    AFAIK (which admittedly is just hearsay) each company pays for runs of products that meet their specific requirements, levels of QC etc. So you could have products out of the same exact factory with wildly different abilities and quality. I'm all for finding bargains, I love deals and bargains...
  • Post in thread: What was your most interesting recent non solar project?

    Speaking of getting out of the way! 😳😳😳
  • Post in thread: Adding batteries to Bluetti

    No, as long as the DC voltage that you are inputting into the PV port does not exceed the maximum specification then you can plug anything you want into it, regardless of where it's coming from.

  • Post in thread: Delta Pro over voltage shutoff smoke

    I would personally weigh my options. If you are unfamiliar with electronics at all I wouldn't even bother opening your unit up at all. As it stands, you have a good chance of reselling it to someone who could fix it or who would have a use case that doesn't need the PV input at all. If you...
  • Post in thread: Extending runtime of a small power station

    Almost every battery that you buy should have a BMS. And as long as you get a decent enough charger it should have built in "smart" features to turn off on its own once you get to the right voltage.
  • Post in thread: Cheapest 48v 50ah battery I've found so far. $409.99 free shipping

    I have no way of proving this, but everything I've seen online indicates that DC House and EcoWorthy are the exact same company. But that's just my opinion of what I've gathered, that's not been proven.
  • Post in thread: Be aware....Just tried to order $2000 worth of batteries from <vendor> and they rejected my C Card. That produced a Fraud alert and cancelled card.

    I'm assuming they make up for him with a much higher volume being sold on Amazon though?
  • Post in thread: Experience sharing - Buying a 51.2v 14.33KWH Wall mount battery pack from Shenzhen Basen Tech (US stock)

    How are these going so far?
  • Post in thread: Where to put the inverter?

    Huh? That's how you act when people ask you to back up the things you say? Weird. I mean, you're correct about the stranded wire, but IT IS NOT a commonly known thing, why act flabbergasted when someone doesn't immediately bow down to your answer?
  • Post in thread: Looking for 48-52" 200W panels

    Or this one claims to be 250w and only 54.75 inches https://a.co/d/9sHbPpZ But yeah, if you need those exact dimensions it looks like the 180 watt panel that @Drunk Engineer posted is about the upper limit of watts you'll find under that size.
  • Post in thread: 36V system?

    36 volt is entirely possible, but there really isn't that much stuff that supports it. All of my stuff right now is currently 36V and although I got a good deal on the batteries and everything, I wished I had done 24V or 48V instead. If I had saved up the amount of money that I had spent on my...
