    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.

    NEW YORK residents:
    On 3/2/2023 New York passed a law banning the sale of lithium-ion batteries for mobility devices that are not certified to UL 2271, and the assembly and reconditioning with cells removed from used batteries for commercial sale within the state of New York (more details here). New York residents, you are solely responsible for researching, understanding and complying with all pertinent regulatory rules, laws, statutes, and NY safety standards.

    Safety is important to us, we don't want people to get hurt or property to get damaged, especially when working with DIY and/or second-life lithium-ion batteries. All batteries everywhere are inherently dangerous, so we urge all who work with DIY and/or second-life lithium-ion batteries to take safety seriously so as to avoid causing any harm to self, others or property.
