These batteries are capable of 50 amp constant discharge, with a 10 second pulse rating of 120 amps. Cycle up to 1000 times before significant capacity loss occurs. The rugged assembly of the products will ensure that your pack will last for years, not months. Can be repeatably charged to 100% in 15 minutes. Charge only with Lithium chargers with an A123 (LIFE) mode limiting charge voltage to 3.6V per cell. An Astro Blinky for A123/LithiumWerks is highly recommended as a balancing aid for these cells.
