2000 mAH High Discharge 18650 Lithium Ion Cells. These cells are factory new and guaranteed original from LG Chem in Korea. They were NOT sourced from secondary suppliers commonly found online. My company uses these cells to manufacture high power battery packs for a line of DC powered welders used in the plastic piping industry. We are offering the raw cells for sale on Amazon to help offset LGs purchase minimums. If you have any questions about the cells or their capabilities please do not hesitate to contact me.
