Hello HKJ!
Your help and expertise is very much regarded, so thank you very, very much! :-)
I just received the Keeppower 18650 3200mAh P1832U (Blue-white) today.
On your webpage, you have an interesting article about "The Anatomy of a Protected LiIon Battery": https://lygte-info.dk/info/battery%20protection%20UK.html
It states as following: "The wire is connected to the plus pole on the battery and the other end goes to the circuit in the bottom of the battery. The vent holes, from the pressure valve, can also easily be seen here, including two more."
I can't see or touch the wire which should connenct the plus pole and the bottom of the battery. Doesn't the Keeppower USB feature such a wire? I have another proceted battery where I can easily touch and feel the wire. And if so, is the protection good enough anyway? I also can't see any vent holes. Like you mentioned before, they might be hidden underneath the cover, right?
