Amazing 1kWh Bulk Battery Pack deal! This listing is for 5x 20-cell eScooter packs totalling 1kWh, with each pack containing x20 Eve ICR18650 or LGM26 cells in 10s2p. These packs are reclaimed from e-scooters and are "untested". Cells are coming in at around 90% of the original capacity. Can be used for building Powerwalls, for replacing Ninebot ES2/ES4 internal scooter battery, for powering e-Bikes, or for any other 36v devices requiring up to 5.2A per pack. For higher amp applications, combine multiple packs in parallel (combine using 3x Amp Booster or 12x Amp Booster). There are bolt holes on the bottom that can be used to secure it and it also has easy access to the cells.

Most packs contain Blue EVE ICR18650 3.7v 2.55Ah cells. Some packs may contain another cell brand and color.

    WAKING THE BMS

    Awakened battery packs have a blue LED light on the top edge, near the XT30 connector. If your pack has no blinking light, it needs to be awakened. There are several ways to wake a BMS. The easiest way to wake this BMS is to fully charge the pack via the large discharge port, then apply voltage to the small JST PH 2.0mm 4-pin connector. The BMS LED light will turn from blinking slow red to blinking blue. See below for more instructions on waking up the pack's BMS. Obviously, the packs will not wake without charge. Charge these packs using the NEW 42V 1.7A BATTERY CHARGER + MU CABLE BY XIAOMI or this variable chargerMake sure you fully charge the pack as soon as you receive it and before using it.

    Battery Pack LED Indicator Lights

    • Blinking blue = BMS awake
    • Blinking red slowly = Battery charging
    • Blinking red and blue = Battery trickle-charging
    • No blinking light = Battery BMS asleep, needs waking
    • Blinking red fast = Potential BMS or cell problem

    Charger LED Indicator Lights

    • Solid red = Charging
    • Blinking red = Trickle charging
    • Green = Fully charged / Not charging

      When the charger is plugged into your battery pack you should see the charger's LED indicator light turn solid red and the battery pack's LED indicator light blinking red. If you see the charger's LED indicator light blinking red (trickle charging) and the battery pack's LED indicator light blinking red & blue, leave your battery pack charging for an extended period of time until the charger's LED indicator light turns solid red. See video below for additional steps.

      Harvesting Cells

      Scooter packs are great for harvesting 18650 cells as they typically have very low cycles.  To harvest the cells you have to crack packs open and extract the cells,  you'll have to cut and clean the Nickel interconnects using snips.

      Once the Cells are out and clean you will have to test them using a charger like this.

      Typical Capacity: 2600mAh
      Nominal Capcity: 2550mAh
      Diameter: 18mm
      Length: 65mm
      Voltage nominal: 3.6V
      Charge voltage cut-off: 4.2V
      Discharging cut-off: 2.5V

       

      This video shows you how to DIY harvest the cells, based on a very similar pack:
