This is a very large LiIon cell, about D cell size, the capacity is higher than 18650 cells, but does not follow the volume, that is 3 times a 18650.

The discharge curves looks nice up to 10A, but the cell cannot handle 15A.

Conclusion

The cell has more capacity than any of the smaller LiIon cells and maintains a higher voltage during discharge. The price for getting this is larger size and more weight.

This is an acceptable cell.
