Untested packs are in unknown condition and sold as-is, not eligible for refunds or returns, no exceptions.

For DIY use, requires the use of a CAN Controller dongle to activate/wake the BMS. Instructions to DIY your own dongle can be found here. Alternatively you can also perform this hack to wake them up. You can also replace the BMS or just harvest cells.

These packs don't have glue, making them perfect for harvesting cells. To do so you have to 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.

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.
