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

Once charged, some packs will automatically turn on, others will require you to...

Step 2:
 Bridge the negative pins on both connectors together using a jumper cable.

Applying 42v to the small charging port will also take the battery out of hibernation. If you don’t have the small connector you will have to cut the original connector and solder in your own. XT60 connectors work great here.

Step 3:
 Use our Dongle or Arduino controller to prevent the battery pack from turning off when you apply a load above 1 Amp.


Scooter packs also available without Aluminum enclosure

Normally comes with female connectors attached, so you will need to get the male connectors.

To charge these batteries:

Scooter packs also available with full Aluminum enclosure 

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.
