Samsung 25R 18650 (Canada) – 2500mAh Green Wrap

FROM MOOCH:  “…moderate maximum temperature of 77°C at 20A.  Five additional cycles at 20A showed less than 1% loss in capacity and almost no voltage sag. A 10A discharge done after this showed a 1.2% loss in capacity. This is typical damage for a cell operating at its CDR.  While operating any cell at its rated maximum current causes damage to the cell, I would expect decent cycle life from the green wrap 25R5 at 20A. A discharge at 25A brought the cell temperature to 91°C and dropped the voltage considerably. That’s too hot and will significantly speed up the damage done to the cell. This is a 20A cell.”
