    Thanks for the tear down, I have a bosch system on my commuter, I have been looking at a conversion kit on another bike, and this has convinced me that's a brilliant idea, rather than committing to another bosch which can't be serviced DIY, however I will add, my bike from 2018 is still going strong, after one early motor failure, it was fixed under warranty no issues since.

    So it is a 36v 13.4ah battery with 40 cells so cells must be 3.35ah 10S4P. They are arranged in 4 blocks and, from the video, it looks like the 10 cells in each block are configured in 2x4P blocks plus 1x 2P block.

    I had the same battery in my Trek Powerfly, it failed after the 3rd charge, completely dead, It was replaced super quick by bike dealer who told me it seems to be happening with more regularity, so far the replacement is good, 30 charges later.. great video, thanks.

      There has been an error for some of them. So the error comes becuase that the battery has not been updated before first charge.

    That clip you are wondering what it is, is part of the attachment that secures it to the bike, it is sort of a safety latch, you unlock the battery with a key and the battery pulls out slightly from the bike frame and is stopped by that safety latch, you then have to press on that clip to remove it from the bike, safety latch like on a car hood.

      it is the same as powertube 500 with another row of batteries on top. And the 750 is like 625 with another row on top. So the question that remains is how much amperage the cells have.

    • @fayezmohammad745
      @fayezmohammad745 2 года назад +4

      The cells they use 18650 with 3.4 ah capacity.
      4 x 3.4 = 13.6 ah battery. 500 w
      5 x 3.4 = 17 ah battery 625 w
      6 x 3.4 = 20 ah battery 750 w

      How much are you riding it? In what mode are you riding? Mine is 3 years old now and just beginning to lose steam, but I'm topping it up all the time. Sometimes, I let it go to zero and barely get home, but if you ride in Tour or Eco all the time like I do, it's not bad. Get about 49 miles on a charge.

      You will need positive and negative wires of 42v charger and the third wire need to be positive 5v source and negative together.
      The 5v supply will enable the charger to work and it acts like a key. 👍

    @marvinhensbergen1515 3 года назад +8

    how great and easy it would be if they are made consumer friendly, just screw the bottom off, and the cells slide out, and you can insert new ones, and done.. Just like AA batteries. Much less e-waste and easy repairs this way. It's a nasty thing they are doing with e-bike batteries. They really want to sell you a new battery every 2 years. They could make a 10 year lasting e-bike battery easily using LiFePo4 cells and decent battery management. Also, let the user choose to charge to a custom level like 70 or 80%, make your battery last alot longer, but thats not what they are interested in of course.
    Proof...?
    1) batteries are way overpriced
    2) no user defined charge level
    3) no internal reserve capacity margin implemented
    4) no slower charge speed settings
    5) prevents third party batteries
    6) prevents the use of smart third party chargers that can extend your battery life
    7) no use of long life cells like the proven LiFePo4 cells
    8) no active cell balancing promotes charging to 100%
    9) range extenders are not used or charged in paralel and requires to charge to 100%
    And this is prety much the formula that all ebike builders follow.
    The only alternative is building your own ebike.
    There is just no incentive for them to do it in any other way, the amount of profit on batteries over de lifetime of the ebike are huge.
    I had a DIY ebike with a LiFePo4 battery that lasted for almost 10 years , always fast charged to 100%.
    With slower charging and limit to 80%, it would last at least 20 years for sure. And costs half that of what Bosch charges for the same capacity.
    The same is going on with Mobile phones BTW. They don't give you the option to charge slower or below 100%. Even apps are prevented from doing this.. Only way is to use an app to let you know you need to pull the plug at a set percentage. Making batteries also hard to replace, making sure people keep buying new smart phones, even if it's just because of a degraded battery.

    • @vexy1987
      @vexy1987 Месяц назад

      They definitely should be make these more service friendly for professionals, but Lithium batteries are easily nudged into thermal runaway if mishandled, so I guess these system have to keep consumers from attempting DIY repairs. I worked out how long my battery charger took to take my battery from 20% to 80% and added a smart plug to switch it off... when I cared to. These days, I don't baby the battery, it's 5 year old and still going strong.

    That's what you call engineering overkill...
    I doubt they even repair these when they get broken while in warranty. Probably just replace it with a new unit and therefor not requiring battery repair centers. At the same time making it impossible for the user to repair it via 3rd party out of warranty and thus making him buy new overpriced over engineered pack.
