48v 10ah 480wh E-bike battery 13s2p 21700 5000mah

These are beautiful Ebike batteries recovered from ebikes. They use one of the best 21700 5000mah lithium ion cells. They are one of the best cells on the market. Every battery is checked to have good voltage and be in working condition. They have a 15a BMS on them already and if you don't want to use the original connector just remove the screws on the lid and open it up. You will see the red and black charge/discharge wire and you can add your own connector there. We don't have the actual physical key for the lock on the battery case so we bypassed it. Now the BMS is active and working like normal. If you find a physical key to turn the lock on and off you can reconnect the 2 white wires.

These batteries are clean and come in an aluminum enclosure. They are not dirty and were not used too much so you can expect these to have a lot of life left in them. There are 26 cells in 13s2p configuration that are one of the best cells on the market. Just charge them all up and parallel them together.

We recommend to limit the charge to 2a per module and discharge to 15a per module.

At this price it is worth it for just the cells. You get the cell holders, BMS, and enclosure on top of it. Overall just an amazing value.
