    Great info. Will this power supply spec be ok for similar application? DC Power Supply Variable, 30V 5A Adjustable Switching Regulated Power Supply

    Where can I find the charger you used? I don't know where to get a charger where you can change the voltage and amperage.
    Thank you.

      It's called dc power supply variable, lookup on Amazon and you'll find many.

    What about a steady red light. Then next day it charges although depleted it has two bars of light. That quickly charges to full. But when taken off charger and it goes back to 2 bars

      Checkout this video, I had the same issue that you are talking about and I documented the repair in this video:-

    How did you electrically disconnect each battery?

    • @Xx_TheCuriousBrain_xX
      @Xx_TheCuriousBrain_xX  7 месяцев назад +1

      I didn't and you don't need to disconnect each cell in order to charge individuall. Simply connect positive to positive and negative to negative, you will be able to charge normal. Just pick positive negative correctly while making sure they belong to that individual cell only..use multi-meter to assure positive negative are correct before charging.

      @@Xx_TheCuriousBrain_xX I think I understand it now the resistance the other way around the circuit through the other 19 batteries would be so high as to limit current.

    • @Xx_TheCuriousBrain_xX

      Exactly, so charge them individually. I don't believe you need to charge all of them, just the one that's low...most of those should all match, just 1 or 2 that's below average volume that cause the damage in unless all cells are below 3v or so. Once every cell matches, then regular charger should pickup charging....also do subscribe if you haven't already, to help support...thnx!!!

    Greenworks 80V, Masterforce 80V, Kobalt 80V, and Snapper 82V are all the same and made by Greenworks.

    How do I get a charger like yours? Can you describe, brand model, etc

      It's called dc various power supply:-

      @@Xx_TheCuriousBrain_xX Don't you need to get an 80V or higher charger to charge 80V batteries as a whole? Your link shows the charger is 30V only. I know your case is fine since you were just charging individual cells. Thanks!

    • @Xx_TheCuriousBrain_xX
      @Xx_TheCuriousBrain_xX  2 дня назад +1

      @Louis-do2et You are absolutely correct about both of your statements. I shared the link of my variable power supply that I was using to charge individual cells which is 30v per another viewer request who wanted to purchase similar charger but I can't charge entire 80V battery since it's only 30v. Mine is good to balance cells before actual factory charger will pickup charging. This method works great, I was able to repair Ryobi power tools battery and more with this method

  • @rondamon8004
    @rondamon8004 5 месяцев назад +1

    These batteries should come with a balancing button or something, because with the use they get out of balance...Oviously, companies are not going to do that...

    • @Xx_TheCuriousBrain_xX
      @Xx_TheCuriousBrain_xX  5 месяцев назад +1

      That's what BMS (battery management system) is for but it's not smart enough to only charge cells that are unbalanced. It basically stops charging when it detects unbalancing which I guess makes sense because there is no programming or processor that can calculate all that in these BMS. Now you know why expensive cars like Tesla are way advanced as it shows you individual cell voltage and you will know exactly what cells are bad etc.

    Question: I've charged individual cells to with .01. Each cell now has 3.88-3.99v. Put on charger and still blinking red. Any ideas. When tested, 10 cells were close to 3.31v. Battery is one year old. Any ideas on how to proceed?

    • @Xx_TheCuriousBrain_xX
      @Xx_TheCuriousBrain_xX  7 месяцев назад

      Sounds like you are doing pretty well. Test total voltage of entire battery pack to make sure it's 70v + otherwise it's possible you might have missed some of the cell.

    • @taknmyshot
      @taknmyshot 7 месяцев назад

      ​It's a 60v, 8ah. Total voltage is 58.3. It should work. This is my first time, but can't imagine it not working. I'm about to charge it up directly with another 60v fully charged battery. That's how I started the project. Started with no charge bars showing. After repeated charges, had three bars. Even worked in the riding mower when it was the only battery installed. Makes no sense to me.

    • @Xx_TheCuriousBrain_xX
      @Xx_TheCuriousBrain_xX  7 месяцев назад +1

      Yes it doesn't make sense. Okay, so if it shows 58v, then technically it is close to full charge. Do a load test to see if it output fine...maybe use it for a little bit and then try to charge to see if the charger pickup. I don't remember on this battery model but normally BMS also has buttons to reset itself, maybe Google it on how to reset BMS, that might help. At this point, sounds like your battery is charged enough, BMS is being an issue now that's preventing to charge the battery.
