This is a LiFePO4 cell in 18650 format, this means lower capacity, lower voltage, flat discharge curve and long lifetime.

The two cells are well matched, the maximum specified load is easily handled.


This is a good cell with high capacity for a LiFePO4 cell. The flat discharge curve can be very useful for some applications.
