Unboxing! This is a holder box with wires for 18650 battery.
I ordered it at Aliexpress, and only after a mere 55 days it is finally at my doorstep. Why do I need it? You may remember my review of a decent mp3 portable radio from China. It has a built-in lithium battery, which obviously degraded in the five years since purchase. So I decided to install this battery holder inside the radio, and fill it with 18650 leftovers from my electronic cigarette. New lithium 18650 are not good enough for vaping after a year of use, but still can operate decently in a radio. Don’t forget to watch the mp3 radio review.
