These packs come with a custom BMS connector, so to add your own BMS you'll need to find the matching connector or adapt it to add your own connector. FYI,  Untested batteries are in unknown condition and are sold as-is. Untested batteries may be unbalanced, so you may need to try to balance them before using them safely. If your pack doesn't end up balancing out, you need to be prepared to DIY repair it or harvest the cells out of it. No refunds or replacement on "untested" batteries.   Pack Specs Voltage: 24v Capacity: 9200mAh Current: 480A Continuous discharge: 280A Configuration: 8s4p BMS: Not included Cell Specs Brand: A123 Chemistry: LiFePO4 Code: ANR26650M1A Style: 26650 Dimensions: 25.85mm D x 65.15mm H Weight: 70g Nominal Capacity: 2300mAh Voltage (nominal): 3.3V Internal impedance (1kHz AC typical, mΩ): 6 HPPC 10 Sec Discharge Pulse Power 50% SOC: 200W Recommended standard charge method: 1C to 3.6V CCCV, 45 min Recommended fast charge Method to 80% SOC: 4C to 3.6V CC,12 min Maximum continuous discharge (A): 70 Maximum Pulse discharge (10 seconds, A): 120 Cycle life at 10C discharge, 100% DOD: Over 1,000 cycles Operating temperature range: -30°C to +55°C Storage temperature range: -40°C to +60°C   Product video:   __ 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 specifically described as “untested” or “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.

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.
