A high capacity cell from Sanyo/Panasonic, this version is improved over the NCR18650B version, but the specifications are the basically the same (My discharge curves are not).










The chart looks good with fairly good tracking between the cell (Sorry about missing one 7A track).





The cell has a reasonable temperature at 7A.

















Conclusion

A fairly good high capacity battery, but superseded by the NCR18650GA
