Lowest Internal Resistance 18650 Cells
Internal resistance (IR) determines how much voltage a cell loses under load and how much heat it generates. Lower is better for high-drain builds. A cell with 10 mOhm IR will sag far less than one at 250 mOhm when you pull 10A through it. These 18650 cells have the best IR numbers in our database.
