18650 Battery chemistry FINALLY explained 18650

This chemistry adds nickel to the IMR chemistry above, making it a "hybrid" chemistry. It combines the safety and low resistance of manganese and the high energy of nickel. (Pictured Battery Bro Samsung 25R. Wink, wink!) The resulting battery chemistry gives you a reasonably high capacity and a high discharge current.
