    We recommend fully charging this pack as soon as you receive it. Charger not included.


    Harvesting Cells

    If you prefer to harvest the cells, you have to remove the rubber around the cells and extract the cells as shown here. 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.



    Note that these are reclaimed packs, so the actual cell voltage you receive may be lower than the label shows. These items are sold for DIY and Second Life purposes. Listings that are “untested” as sold as-is and cannot be returned, exchanged or refunded. We make no guarantees that all cells will be usable. Even when sold as “new”, “NOS”, or “like-new”, they may be in less than perfect condition. Buyer is responsible for proper cell recycling/disposal. Sold as-is. No refunds.

    If you buy a product from us and then realize you don't have, or don't want to acquire, the tool(s) or information needed to make our product(s) work for your specific build, this does not constitute valid grounds for replacements, exchanges or refunds. You are responsible for doing your due diligence before making any purchases.
