5x Ninebot 36v 15.32ah 551wh E-bike battery with BMS

For $199.99 you get 5 modules which means 300 cells. Since these are over 300wh, we are packaging these 5 per box to maximize shipping cost efficiencies. Each box with 300wh battery modules are considered fully regulated and require a $37 hazmat fee and UN-4G packaging per box. We are covering those costs and we are fully certified to ship these batteries. So instead of us having to pay $37 plus an $8 box to ship 1 battery we are packaging these 5 per box.

Each of these modules have 60 18650 cells in 10s6p configuration with mostly LG 2550mah cells. If you get a pack with different cells they will be a quality brand trusted by a major company. I've seen some scooter packs have LG or EVE cells but the ones we opened all have LG cells. There is also a BMS and the connectors. These were salvaged from popular brand scooters that were recycled. The cells are perfect for salvaging and these are all at least 3c cells so they are a perfect balance of power and capacity. These BMS units I'm not sure if they work as is, I see some listings on ebay selling these for 4x the cost but they say the BMS is "flashed". I'm not sure what they mean by that and I'm not sure I recommend charging and discharging through the XT60 connector because we don't know for sure if charging through the discharge port provides protection from overcharge. I recommend salvaging the 10s6p modules or the cells then adding your own BMS. If you don't get voltage from the connector it's because the BMS is shut off. If you know about the BMS and can reuse it that is a bonus. Every pack we opened the cells were fine and tested great.

You can easily open these packs with a regular phillips head screw driver. The outside case has 9 screws. You can pry the lid off easily. Next there are 8 screws under the yellow glue. Use a pointy tip phillips head tip on a drill, press down hard, then unscrew so you don't strip the bolts. When you do the first one it'll take you just a minute to do the next ones. These are nicely shaped so you can press down with leverage without the pack tipping over to get those 8 bolts out. After those bolts are loose then you can pry the module out of the rest of the case. Or you can simply drill out those 8 bolts, they're small, less than 1/2" long.
