These are old and rebranded cells, the sells were 7000mAh WHEN THEY WERE NEW (This is not really said anywhere. The specifications on the page are COMPLETELY wrong). Mine all tested above 6300mAh. The batteries are at around ~18mOhms internal resistance. At the price, this is still all good product at around 0.18$ per WattHour.
Very bad seller! Waiting 2 month and no batteries. Im waisting time! DO NOT BUY FROM THIS SHOP!!
