  • Post in thread: A little advice about Amazon returns and how to cover yourself

    Same here...Kohls and 25% coupon every time I have returned something. Never had an issue. Plus the gals at the retuen desk are hella cute. So I retuen 17 items. One at a time.

    Watch the Project Farm youtube videos on battery tests for fun and pleasure.
  • Post in thread: CATL purchases from Michael B Caro

    Please ensure that it is united, not fake, woke, inclusive, entitled, overly-concerned and whiny. If you can add impetuous and other self-damning adjectives, please do. .
  • Post in thread: SUNGOLDPOWER 6000W DC 48V SPLIT PHASE PURE SINE WAVE INVERTER WITH CHARGER

    As an engineer and enterprise IT guy what is instantly a deal killer is that a product this expensive and configurable has no logging. EVERY GD THING POSSIBLE at all time should be logged at a very granular level, and they should be able to get that and runbook to find the logic involved, or...
  • Post in thread: Summary of my battery options from China, lifepo4 3.2v 280ah cells.

    Thanks for sharing and for the thread. I just went through all of this, found all out the same things and decided to buy 32 cells through Micheal. Done and done.
  • Post in thread: Heltec (JK) 200A Smart BMS with 2A Active Balance

    We could build in jumpers with 4' leads in order to conveniently supply that occasional 6v or 9v source. A 9v battery or pack of 4 AAA with a switch could sit there and be available and viable for many months of not years since the batteries will have no load on them. Then all we have to do is...
  • Post in thread: Roast my solar install.

    Oh yeah me likely. Very clean and spartan looking. Thanks for sharing. Would love to see the parts list and where you bought your stuff from too :D

  • Post in thread: 1000 watt modified runs longer than 1500 pure sine

    Second that. However he could just branch off the supply leg for the fridge to the MSW and let the PSW handle everything else. Eventually the fridge will die and the problem will solve itself.
  • Post in thread: Tilted solar panels vs more flat panels for off road use

    There's no such thing as "over panel" :) I plan to just scooch my rig through the day to keep the sun directly to my back and off the sides of the rig, which will also help with shading from the A/C etc. I might even put panels ON the back wall vertically. And those I might could tilt up 45...
  • Post in thread: Need help! 48 volt caught fire

    Your DC-DC converter is only rated for 30A. My initial guess would be that your 12v batteries were basically dead and had a high demand, or you had such a load on your 12v system that it far exceeded the 30A supply. If at first you don't succeed, fuse, fuses again. I think it's recoverable in...
  • Post in thread: 48v vs 24v system - am I limiting myself?

    Howdy, I read THIS thread, very informative. I still have questions though about my choices of HW, BMS, inverters, SCC and so on. I purchased 32 of the 272ah cells and I think I want / need all that juice, I'll live with the weight of it all. At the time I was thinking of doing 2x48v parallel...
  • Post in thread: What REALLY requires a pure sine inverter?

    Your statement is an over-simplification. When you rectify pure AC you get a DC pulse that is almost contiguous and the use of capacitors help to mitigate the pulsing of the voltage and current at the frequency expected without clipping, jitter, higher total harmonic distortion and blank-outs...
  • Post in thread: Cable Crimper

    Dennis, if you buy tinned lugs you can sweat the bare copper with a tiny bit of solder and have a great electrical and physical connect. I do it all the time and I do it for my setup. This is way cheaper and takes a few minutes. I think I've described my process here before in some thread. For...
  • Post in thread: 32 280Ah Eve "grade a" from Shenzhen Luyuan (Amy Wan)

    Wow what a detailed and informative documentation, much appreciated! I think you could publish a concise How-To wiki on a 48v setup and really save folks (like myself) a lot of time and mental energies. And you used only the Renogy unit and a BMS or two to do all of this? I think I want to...
  • Post in thread: Can an MPPT Controller use an Alternator as an Input?

    Battle Born recommended this to me to charge lithium batteries while driving, from the alternator. There's a downloadable spec sheet on the website. Perhaps you can call them with question to better determine if this would benefit your situation.
  • Post in thread: Free Energy Generators

    1000%!! You should never pay for electricity or gasoline again, that's soooo 1950's. Thanks the gods you found the secrets on youtube. .

    How much are they paying you for all this sponsorship? Don't let Will find out!
  • Post in thread: Passive Top Balancing ? How/Why does it work ?

    If you read along this rail (from negative to positive) with a voltmeter from the first cell to the last cell, even that value with change. If all else (ideally) is equal, why would there be variation in the reading? There is no pressure or guidance or compelling of electrons to auto balance...
  • Post in thread: Hello my name is Dan I live in California and I'm excited about lithium

    Welcome to the forum Dan. The title of this thread made me laugh a bit, sounds like an intro at a Lithium Anonymous meeting :) The whole room then replies in unison "Welcome Dan".
  • Post in thread: source for 120v efficient refrigerators

    I see you point. You know, I hadn't really looked at it from that perspective before, rather quite brilliant. So what we need to do is buy our refridgerators from the future. I'm on it.
  • Post in thread: B&H Photo/Video for Solar Power

    I'm a big fan of B&H and bought plenty of things when they have it specifically "on sale". Great company to deal with.
  • Post in thread: Is Cell Compression Necessary?

    So this thread has 675 pounds of pressure, rods with red springs, rods with 18 inch pounds max, and a full 5mm of spongy cell metrial bwtween each cell. So which is it? It seems like some of these things can't co-exist together and be true at the same time.
  • Post in thread: The good old days....

    . . . yeah, I did too *cough* (dream of Jeanie) This show warped my young psyche, causing me to grow up with the impression or somewhat expectation that when I grow up I'll meet a busty vivacious blonde that would do my bidding and say YES MASTER. It never happened :(

    We're glad you lived to tell the tale!
  • Post in thread: All this record breaking heat really makes me want to . . .

    My god, only you people can ruin a chat thread with technical mumbo-jumbo :D Save the techness for the tech threads and breathe a little already. Who wants to get sloshed or get naked? .
  • Post in thread: Can bad cells hurt good cells?

    "Can bad cells hurt good cells?" - and nothing about the cell on cell crime statistics at all.
