Panasonic NCR18650-BD

Mid-range 18650 cell from Panasonic. 3180mAh capacity with 10A continuous discharge. Extremely common in budget pre-assembled e-bike packs due to its balanced capacity-to-discharge ratio and lower cost compared to the NCR18650B. If you open a cheap AliExpress or Amazon e-bike battery, there's a good chance you'll find these inside.

In brief: 18650 NCA battery cell. 3200mAh capacity. 6A continuous discharge.
