BlueSwordM, even fastech says shipping unavailable for Turkey so it seems aliexpress is my only source and it is better getting cells with Bpost, it cost only 5 usd for 10pcs NCR18650GA from aliya store, thanks to you i have known this seller. They told me they never sell fake batteries.
Have you bought from them and did a discharge test at higher amps ?
I have been looking at ‘’Second Life Storage & Solar thunderheart’s reviews. He talks about charging with standart current which means 1.6A for NCR18650B batteries.
I have tried it with my charger and i can only get 3200mah with 1.6A Discharge if only i charge my batteries (from liitokala stores) with 0.5A and i read 84mOhm internal resistance so i am sure these cells are not original. I have original NCR18650Bs with 32mohm IR and they are 3 years old i guess. meausered with same icharger 3010B.
I will do further testing with stronger contacts as ’‘
’’ mentioned. Will see if it makes any difference.
