LG 18650 E1 2100mAh (Brown)
Sorry, no data on this cell.
The cell is a high current cell and has very low internal resistance.
Each test does discharge the cell slightly, that is the reason for the seperation between the tracks and because they have no protection the test run all the way up to 15 ampere.
This cell shows good test result, and I will rate it as a very good cell, expecially if you need high currents.
