Hello, I am very happy that the battery has arrived after almost 3 months. Normally an order from China to the Canary Islands takes between 10 and a maximum of 21 days. (AliExpress Standard Shipping) These goods could only be ordered via (Aliexpress standard saving). Besides the very long delivery time, there was also no tracking and tracing, which I don't think is good. I also noticed that 1 battery, although provided with a circuit board, has already had a deep discharge. Maybe due to the long shipping. It's a shame if a new battery with 2600 mAh no longer has 1800 mAh. I hope that by repeatedly charging and discharging the battery at least 2300 to 2400 mAh.
its works except that the black wire is not properly connected. It is not connected to a minus, but to a plus
