    U don’t want lithium batteries in your home……. lithium are a nightmare in a fire situation

  2. somewhere on the earth on August 27, 2020 at 2:59 pm

    It is actually expensive
    I have installed 150Ah lead acid at my home. & it last long to 7years. And i bought it new in 200$

  3. Braeden Posey on August 27, 2020 at 3:00 pm

    Think they would work on a golf cart? I need to swap out my deep cell 72V system gel.

  4. danz409 on August 27, 2020 at 3:03 pm

    yea. pricing on these is NOT stable… $200 is the absolute cheapest one i see on ebay right now. other than the 2 in that price range 3rd in line shoots up to $300 for 1 battery.

  5. I-Love-CO Mountains on August 27, 2020 at 3:04 pm

    TIL $950 is "dirt cheap" lol nice

  6. Charles Hines on August 27, 2020 at 3:05 pm

    Is that CAN communication the same that is found in some European cars? I have a Volkswagen and all of the electronic modules are connected on a CAN bus. It can be a good thing because it will tell you if any bulb is burned out but it can make those cars a nightmare to work on too. Detecting bad bulbs is far from all it can do though, with the correct scan tool and the courage to mess with that thing you can do a variety of things. You can also seriously F— up your car if you have no idea what you are doing or do it wrong in any way so it is NOT for the faint of heart!!

  7. Good 4You on August 27, 2020 at 3:05 pm

    What’s the model of the voltage meter and from where you got it.
    Thanks

  8. tahir mehmood on August 27, 2020 at 3:06 pm

    Why do I like watching our video I like a lot?

    Nice haircut!

  10. john howard on August 27, 2020 at 3:06 pm

    Will :

    I’m not building a reproduction of
    the " little house on the prairie " !

    14×14 cabin w/loft . At later date
    a 14×14 addition will but onto back of it . Here’s where YOU
    come in , I NEED YOUR HELP to
    spec out a solar setup to power
    this cabin (w/addition ) ! To to make this project palatable for
    Wife ( aka / DREAM KILLER )
    You guessed it , it HAS to have
    it ALL !$ Will have to have enough
    juice to power all modern conveniences inc freezer & a/c
    I need to know what to get , where to get it , and how much it’s going to cost !!$$ I live in Middle Tenn.

    THANK YOU VERY MUCH

  11. John Doe on August 27, 2020 at 3:07 pm

    Super safe he says, lol! (house burns down the next day)

  12. John Moore on August 27, 2020 at 3:08 pm

    $950 for a battery is not cheap….

  13. David Ulmer on August 27, 2020 at 3:08 pm

    I’m curious about the math here. If an AGM battery at 160 ah is $350 – $450 for a new battery, you would have to buy 4 of these used 40 ah batteries to have the same capacity which is $600 (with no warranty). Correct me if I’m wrong, but how is that cheap.

  14. Matti Virta on August 27, 2020 at 3:09 pm

    150$ one battery NOT have cheap, wery expensive, were i found thailand thsi but cost less than 60$ one battery i need 4 pcs.

  15. Xanthan Gum on August 27, 2020 at 3:12 pm

    Will Prowse is a sexy little bitch. I’d like to slap him about the head and chest something silly.
    I would short out your inverter somethin serious Billy, owww

  16. Nigel Clark on August 27, 2020 at 3:12 pm

    Very good

  17. Dana Rider on August 27, 2020 at 3:14 pm

    Makes more sense to just keep buying 25 dollar tractor batters from wally, lasts a couple of months at least till ya fall asleep with something running and run her dead. Even so just go exchange it at walmart or buy a new one..

  18. Jacob Vance on August 27, 2020 at 3:19 pm

    If they were used in medical equipment then they were all well maintained and they would need to be swapped out at a time interval well below their expected life. Medical equipment is always preventative maintenance
    .

  19. terry mccorkle on August 27, 2020 at 3:19 pm

    How long did they actually run the heat blower

  20. 4 Friends RVing on August 27, 2020 at 3:23 pm

    Do you think these could be used to replace golf cart batteries?

  21. Marcel Lucassen on August 27, 2020 at 3:24 pm

    Hi, You connected two plugs together but there where two more plugs and my question is are they the same? Will it blow up if you also connect the other two together?

  22. tahir mehmood on August 27, 2020 at 3:24 pm

    hello dear my friend where are you from

  23. Derek Pearse on August 27, 2020 at 3:26 pm

    Love the video just stumbled on. Im looking for a cheap way to charge some batteries over AC on off peak times and the discharge them to run devices during the day. (I could use something like smart plugs that only power on during certain times so anything that’s connected to the battery like a kettle will only use the power from the battery that charged during the night)
    Anyone know of any easy ways to do this?

  24. Nette Leverett on August 27, 2020 at 3:27 pm

    Extremely informative! Thank you😁

  25. David Ahn on August 27, 2020 at 3:27 pm

    Will, I got two U27-12XP’s, and I connected them together, and they don’t appear to be balancing. One was at 13.15V, the other was at 13.6V, 8 hours later, still same voltages. I just reversed the order and plugged in the other male-female connectors and report back. Interestingly, once I connected them this way, the voltages went up to 13.24V and 13.68V. We’ll see if it works.

    If that doesn’t work either, I’ll search your videos for another way to balance them.

  26. James Meyer on August 27, 2020 at 3:28 pm

    hi I have a question I have a valence lithium battery I have charged it down below 20 percent and and I am locked out how do I trick the battery into charging again ,

  27. Max Pyane on August 27, 2020 at 3:30 pm

    Cheap and easy just like my women!!!!!!!!!

  28. john howard on August 27, 2020 at 3:30 pm

    You GOTTA KNOW You GOT ONE HELL OF A GREAT DEAL !!!!!!!!!!!!!!
    I just looked for them on ebay ,
    cheapest I found $150 & up WAY UP !!$$!! Those batteries would
    almost cost as much as materials
    for My cabin !

  29. Quentin Carter on August 27, 2020 at 3:30 pm

    Hi, what tester are you using?

  30. davva360 on August 27, 2020 at 3:30 pm

    Wouldn’t mind something like this for my RV. The deep cycle lead acid batteries are useless. They get fully discharged too easily which ruins them. I only have a single deep cycle battery on my travel trailer but it’s always dead and does not hold a charge.

  31. single looken on August 27, 2020 at 3:33 pm

    sams has great price on 12v 8oo cca, with exchange $100. plus taxs 1yr free warranty!!

  32. Facundo Rutherford on August 27, 2020 at 3:34 pm

    Thank you for this info

  33. Bryon Mason on August 27, 2020 at 3:38 pm

    Outstanding job young man.

  34. Tina Gallagher on August 27, 2020 at 3:44 pm

    I do like this video. the batteries are, the last time I looked, around $600+ each. that’s still cheaper than the 1K for a regular lithium battery. they also weigh around 25 pounds each, more or less, which is still way less than the 100+ pound regular battery. They also have the box, cables, bmi and thermostat and the regular battery has nothing.

  35. James Turner on August 27, 2020 at 3:44 pm

    Can I use them to replace coach batteries in my motor home?

  36. M VariKKODAN on August 27, 2020 at 3:45 pm

    If you could but see when they will be made to stand before their Lord. He will say, "Is this not the truth?" They will say, "Yes, by our Lord." He will [then] say, "So taste the punishment because you used to disbelieve."

    -Surah Al-An’am, Ayah 30

    Those will have lost who deny the meeting with Allah, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it," while they bear their burdens on their backs. Unquestionably, evil is that which they bear.

    -Surah Al-An’am, Ayah 31

    QURAN

  37. Patrick Davis on August 27, 2020 at 3:45 pm

    Hey Will. I have a couple of these in my solar setup. Can you share what charge controller settings you recommend for them please. Thanks

  38. Theresa Price on August 27, 2020 at 3:45 pm

    Thank you for your knowledge 💕

  39. White CIS Cum on August 27, 2020 at 3:45 pm

    The price of these batteries is obscene.

  40. Right-Wing Atheist on August 27, 2020 at 3:46 pm

    Do these batteries have a charge controller built into them?

  41. Luke's Siemens Phone on August 27, 2020 at 3:46 pm

    Think these batteries are used

  42. The Adventures Of Honey & Mark. on August 27, 2020 at 3:46 pm

    Thank you..Might be a option for my travels..

  43. None Noone on August 27, 2020 at 3:47 pm

    which piece of medical equipment did they come out of. I would like to know.

  44. DIY Solar Power with Will Prowse on August 27, 2020 at 3:49 pm

    This video is OLD. These batteries are now overpriced. You can build your own LiFePO4 for dirt cheap: https://www.mobile-solarpower.com/design-your-own-12v-lifepo4-system.html
    Or buy a drop in lead acid replacement here: https://www.mobile-solarpower.com/lithium-batteries.html

    : )

  46. John Crane on August 27, 2020 at 3:50 pm

    Will, have you done or would you consider doing a video on 48V AGM to Lithium golf cart conversion for dirt cheap?

  47. Ted Ciesielski on August 27, 2020 at 3:52 pm

    Good video, can you test CONCORD batteries?

  48. J. Hon on August 27, 2020 at 3:54 pm

    lithium batteries are bad news. The pollution from the manufacturing and disposal is going to bite our grand children all in the ass, way worse than "global warming".
