Sony US26650FT 3000mAh (Green)
- Nominal capacity: 3000mAh
- Nominal voltage: 3.3V
- Chemistry: LiFePO4
This is a LiFePO4 cell, i.e. the voltage is lower and the discharge looks very different from normal LiIon. The two cells are very well matched.
Most of the discharge the output voltage is very flat, voltage mostly depends on discharge current, not on charge state.
This chemistry has lower capacity, lower voltage, but much better lifetime. The batteries looks to be high quality.
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
