These are 10s4p lithium Battery Scooter packs (460Wh). They contain 40 Panasonic NCR18650BD cells. These are great for Building 36v battery packs as they are testing at least 95% capacity. Packs should have ~90% usable cells. Most packs are wrapped in a 1" thick, rubberized gray protective coating.
Any voltage below 30v at the Discharge port is an indication that the BMS is hibernation mode. The Internal BMS can be turned on by applying voltage to the charging port (smaller cable). The battery pack will remain in the "ON" state for as long as it has a voltage of 30v or above and without a load. Applying a load above 1A will cause the battery to shut 'OFF" after 5 seconds then remain off for 60 seconds, ON for 5 seconds, OFF for 60 seconds for an indefinite amount of cycles. Using this Arduino Controller connected to the blue cable will instruct the BMS to remain ON while under load.
Again, most of these battery packs are in hibernation mode, this means that even though the pack is resting at around 30v the output connector shows sometimes 1v to 15v. This means the MOSFETS in the BMS are off.
How to use battery:
Step 1: You have to charge the battery pack to 42v. Charge the battery using a 10s charger like this one: https://jag35.com/products/owrieo-42v-2a-power-charger-with-powerfast-3-prong-inline-connetor-power-adapter?_pos=9&_sid=451c4fcd5&_ss=r
Step 2: Bridge the negative pins on both connectors together using a jumper cable.
Step 3: Use our Dongle or Arduino controller to prevent the battery pack from turning off when you apply a load above 1 Amp.
Normally comes with female connectors attached, so you will need to get the male connectors.
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.
