Another couple of weeks, and time for another video. This time I’m talking about my new OPUS BT-C3100 battery charger from AliExpress.
I had wanted to experiment with some LiOn batteries, and after building a very crude discharge tester for the shaver repair, I decided I needed something a littl more substantial. People seem to like this charger, so $30 and 3 weeks later, here it is.
You can watch the unboxing video here.
