Description

The ANR26650M1A is a 26650 LiFePO4 (lithium iron phosphate) rechargeable cell manufactured by A123 Systems, built on their patented Nanophosphate™ technology. It's designed for very high power output, long cycle and calendar life, and excellent abuse tolerance — a hallmark of LiFePO4 chemistry, which offers greater thermal stability and safety margin compared to standard lithium-ion cells.

This cell is well suited for demanding high-discharge applications where both power delivery and longevity matter — such as power tools, e-bikes, RC/robotics, backup power systems, and DIY high-drain battery pack builds.
