Verry Long time to get battery s.
Capacity is ok (3000mAh), but the discharge continuous current rating is not true. I did several discharge tests (see attached picture) and compared two these cells with original Samsung INR18650-30Q and it can be clearly seen that these cells have higher internal resistance (lower voltage when loaded) and lower max. discharge current. At 9A continuous current the cell was already very hot - 74degC! So the current rating is less than 1/2 !!! (about 8A continuous discharge current instead of advertised 20A). I would like to use these cells to replace the old cells in power tool so max current is very important for me, but I see it will not work for me because it is NOT fitting the specification. For testing I have used: Power load Kikusui, voltage checked by Keithely 2000 v-meter and logged by scope Tektronix DPO7104C. Very profesional equipment. Of course, I have used 4W connection to cell. Temperature measured by laser non-contact thermometer.
