ANR26650M1A: The ANR26650M1A is A123 Systems’ pioneering product, originally designed for a new class of power tools. Applicable to a wide variety of system designs and currently in mass production, the 26650 cell offers excellent price-performance. Power: Over 3000 W/kg and 5800 W/L Safety: Excellent abuse tolerance and environmentally friendly Life: Excellent calendar life, 10X cycle life vs. conventional lithium ion Our batteries use a new type of cell construction based on a dual plate tubular design optimized to deliver very high power with high efficiency. This new design does not use crimp seals and instead opts for a more advanced “all laser welded” construction optimized for very low humidity penetration over the life of the battery as well as stronger, thicker dual plate headers. Nominal voltage: 3.3V Nominal capacity: 2.3Ah Core cell weight: 70 grams Internal impedance: (1kHz AC) 8 mΩ typical Typical fast charge current: 10A to 3.6V CCCV 70A continuous discharge 120A, 10 sec pulse discharge Cycle life at 10C discharge, 100% DOD: over 1,000 cycles
