Question about Samsung SDI 18650 cells: They are labelled 18650-25R, or 30Q, or 22F, or 15M, or 35E, or 29E, or 20S, or 25A, or 22P, or 26J ...
I understand that number (25, 30, 22, ...) means capacity (example : 25 = 2500mAh)
But what is the meaning of the letter after the number (R, Q, F, N...)?Manufacturing technology? Manufacturing plant? Max discharge current? ...? )
Thanks in advance for you answers
