  • Post in thread: 320ah Cells Ordered.

    Check to see if the shipping information is fake. I had that problem one time. By changing the last digit [or two] the information was exactly the same. With the same time stamps. I'm still believing this will be a scam and a huge roller coaster of a journey. Time will tell but the outcome will...
  • Post in thread: Super cheap cells on Aliexpress

    What is wrong with people? Why would you even look at a seller like that? I no longer feel sorry for cheap buyers that get scammed. I'm sad to say this, but they deserve it. There is enough information out there that says don't do it, but they still do.
  • Post in thread: Lifepo4 for 350 amp?

    I think the OP wants a 4s and that BMS does not seem to offer a 4s version. I will second the idea of multiple batteries. Although I do not know what the odds that the rating of BMS's are reliable, I would always take a Chinese spec and drop it by at least 30-40%. Daly makes some high amperage...
  • Post in thread: Beware @Michael B Caro

    Exactly! It's not the buyers fault. When Mike started, he thought he could make some money. He should have thought, what happens if it goes bad? Can I make it right? If he did not have an answer for that, then he should have never started playing the big boy game.
  • Post in thread: JBD Direct Shopify BMS Purchasing ?

    They do take PayPal which gives you some teeth when something does not go right.
  • Post in thread: VariCore battery offer.

    Really good for them. Not so good for you. If you elect to gamble on this venture, I would recommend PayPal or Credit Card. You're likely going to lose out with Aliexpress guarantee. There are a lot of sharks at Aliexpress. Step up, pay more, and get a good supplier. I've had good luck with...
  • Post in thread: BATTERY SELLERS - THE GOOD, BAD, UGLY -- or Jenny (DOCAN) so far so good ...

    I've had good luck with Docan so it would not matter what they say. If they do not have them, it could be because the oompa loompas were on strike, it would not matter what the reason is, they did not have any for sale.
  • Post in thread: Renogy DC DC Charger w/ MPPT

    Read the specs on the Renogy unit. The way I read it, yes it will take your incoming voltage and do what it needs to to charge the battery. There is a spec for the input voltage so it will begin to charge. I could put that down, but then there would be no reason to read the specs. Reading what...

    Or enjoy what you got going.
  • Post in thread: JB Weld versus Loctite for grubscrews

    That may be true. I'm no electrical engineer. Just some butcher that works on German cars. To me, it makes sense that if there is more surface area, the there are more paths for the electrons to flow. Clamping pressure is important but if it's limited [like you mention with these type of...
  • Post in thread: Our NEW GO-TO LiFePO4 vendor...09.20.21

    People should be searching for a fair price when they are shopping. This allows shops to make a couple dollars and keep the doors open. Fair pricing is what the average is selling it for. It takes a lot of time/effort to determine that. It's amazing how many people complain when they get scammed...

    I dealt with Daisy for two transactions. A+.
  • Post in thread: Renogy 3000W inverter...???

    The original purchase that is still under warranty was a great deal. $295. Of course, if it is not working, what deal is that? I'm still optimistic and expect to get all my money back once the dust settles. Well, not all my money back, because I have no problems paying for the original one. I...
  • Post in thread: BIG BIG THX to @off-grid-garage for helping us out here

    I agree with the comments above and that his video's are not sales pitches for products. I rarely trust anyone because there always seems to be some angle that someone is using to sell you something. If there is an angle that Andy has, I have yet to find it. I know there are a lot of hard...
  • Post in thread: newbie questions, solar/lithium in a 5th wheel, where to start?

    The great thing is that there is no wrong way. One thing that should be looked at with a critical eye, is all the options. Weigh them out and figure out what works for you. Don't trust anyone that says 'This is the best way'. The best way is the one that was researched and thought about...
  • Post in thread: New PowerMax Lithium Series Converter/Chargers

    I bought a 300A breaker for my inverter and you would expect it to blow around 300A. After 4 of them, I found all of them were junk. One of them had voltage drop of 1.5v. I went with a fuse. I get that things should have the proper rating and should work like they are advertised. I just know...
  • Post in thread: New PowerMax Lithium Series Converter/Chargers

    WFCO does come with a 20A receptacle but does not come with a 15A breaker. That is done by the RV industry. That is how I would do it. Better that way than to make two different parts and the hassles with inventory. The majority of my converter load is to charge the batteries. If you really...

    You really think you'll get boxes? I bet they're virtual boxes.
  • Post in thread: Beware @Michael B Caro

    So would I, but not when there are crocodiles down there.
  • Post in thread: Beware @Michael B Caro

    When you make a contract with one person, does it matter what the reason is on why they broke the contract? If indeed Michael did get the big shaft, that is the cost of doing business. You got to know your suppliers. I do not believe most people care about why I did not fix there problem. The...

    I'm running 2ga cable to the battery buss bars. No more than 2ft long.
  • Post in thread: 320ah Cells Ordered.

    Even a blind squirrel gets a nut. I'm glad there is one person on AliExpress that got their money back without going through they credit card company or PayPal.
  • Post in thread: Super cheap cells on Aliexpress

    You want to know what the scam is? Send $100 US to my PayPal account [as a gift] and I will let you know. I also have some solid gold bars for sale soon. As soon as the paint dries. Half the price anyone else has on the market.
  • Post in thread: 320ah Cells Ordered.

    Just so everyone knows, I am cheap and my wife calls me a real tight a$$. I wear those badges proudly. That does not mean I buy cheap junk.
  • Post in thread: Beware @Michael B Caro

    Using vasoline or not does not make it better. It's best to just learn a lesson and teach others. Being cheap is a not a badge of honor.
  • Post in thread: New PowerMax Lithium Series Converter/Chargers

    This is the wiring diagram of my panel. Notice in the center of the picture there is a '20A receptacle'. Notice that the green wire is attached to ground. The white wire is attached to neutral. Notice the black wire is not attached. The black wire was attached to a 15A breaker. It is now...
  • Post in thread: Battery(300) Design Open Sourced

    I'm hoping there are others that are thinking this but afraid to ask. Is there a place that can build these boxes for those that do not have a printer or even the skills to play with the keyboard to make it work? I'm more of a mechanical guy that can get most anything working except for software.
  • Post in thread: Beware @Michael B Caro

    I'm certain Michael was not thinking it would happen either. There is a reason why I carry a couple million dollar umbrella insurance. I never plan on using it, but it's there just in case. Everyone could just go to Battle Born and spend big money and get a long warranty from a large business...
  • Post in thread: Our NEW GO-TO LiFePO4 vendor...09.20.21

    Good to hear that someone has got some good products from Docan. So many issues lately, I thought they are going down hill. The larger the company gets, the more problems seem to crop up. Over time, good companies learn from them and polish their practices. Some companies don't, change their...
  • Post in thread: 320ah Cells Ordered.

    So why did you order through this seller? Price too good to pass up? Previous history? Reviews? Just curious.
