Very nice batteries. First two photos tells all. Discharge values are a bit over 4900mAh while charging values are a bit lower than 4900mAh. Internal resistance is a bit higher, around 20mΩ which is also very acceptable for 15A constant discharging rate. I tested 8 batteries in total and all have similar characteristics which proves consistent quality that came from Astrolux. Not only this batteries look great ( my personal taste ofc ), they also act great and so I am VERY happy with this purchase. Above all the price for this quality is great. If you need high capacity 21700 batteries at low price go for it. Bear in mind I tested on Opus which in its own manual says that tested values of internal resistance should be reduced a bit because of the resistance in the very charger so I assume even the resistance values are very close to the truth! This batteries are really worth of buying and so highly recommended. Thank You Banggood and way to go Astrolux!!!
