    The laptop battery need to be tested before used in other configuration , because they can have various capacity ! If one have 500mAh and other 2000mAh the bms stop entier pack wen first battery ritch 2.5v ...

    You should never make it like that. Each battery cell has a different capacity, but in the end, it does not last long and cannot be used. I can never agree to make it this way.

    @mnocum16 2 роки тому +14

    This video shows only how to make used 18650 cells as battery packed, what concern me maybe all those who watched is the lack of safety in making. First is the battery tested individually for their capacity? if any of the individual cells peak its voltage before the rest of the packed is disaster waiting, second is you separated each series with a paper cardboard? lastly if you could buy a spot welder maybe you could buy a soldering iron to solder the bms to the packed since it carries more amps to that connections.

    You could do it from rejected laptop batts. Most of such batts are good but main problem is max current drain. Laptop batteries has max current limit, mostly 4-5 Amps. So , big capacity but low current load is the problem is practice. BMS has current limit much bigger that the batts! That could result batts to explode. For low current rigs it could be ok.

  • @cryzz0n
    @cryzz0n 2 роки тому +15

    What about capacity of each cell? Even new ones, if they are different models, cannot be used together. Also, being used cells, each should have a fuse, in case they become "power consumer" - so if they short internally, they will draw a ton of current and the fuse will pop. And for limiting the current, these are not high drain cells.

    cool man, i got the info i needed from this video, thanks, big time
    At 4:09 , not a good idea. It is better to pre-solder the wire ends, and the area on the circuit board, then solder the wire to the board, the reason why, having heat on the board to long will cause that contact surface to separate from the board. plus if the wire end is not saturated with solder could cause problems. I mean it wont happen every time, but, why take the chance when it can be fully avoided.

    Lithium battery is dangerous. They require balanced charging in the correct voltage on each single cell. These should never be made. Making one of these battery pack can shock you if you connect them in series and if it caught on fire it’s hard to distinguish.

    How do we determine the circuit voltage and amp? thanks

    this is terribly unsafe. never tested anything but voltage on the cells and didnt even bother to mark them to balance each array. youre going to end up with burned out cells all over the place. Good job teaching people how to be incredibly unsafe with high current.

    • @jaypormei1881
      @jaypormei1881 Рік тому

      Agree. This method does the job ONLY by matching the same type of 18650 battery or with identical mAh. Having 5000 mAh and the other side is 2850mAh is ridiculously unsafe to mix. When charging the cells, the 2850 may degrade easily plus ka-boom!

      No. The starter motor requires high current. Generally 1 cold cranking amp (CCA) per cubic inch of displacement. i.e. a 2 liter engine (120cu.inch) will require 120 CCA to start. Diesel engines require double this.

      Parallel makes more amparage's
      Series makes more voltages

      @@hexidev parallel raises capacity if u want to build a accupack with 80A current every single cell must be able to output this current if there is only one cell that will output 20A instead of 80A the current of the hole batterypack drops to 20A!!!

    Outstanding work!
    I couldn't find the spot welder from the link provided? Also can you please tell me about the BMS? Is that what regulates the 12vdc output because I don't see how these batteries can be configured for a 12vdc supply.
    Thanks

      Each set of batteries equals 4.2 volts. He has 3 in series. The bms is on aliexpress just under lost orders. The bms only protects the batteries from overcharge and overdischarge
