A subscriber asked which batteries I used in my (tr)uSDX radio battery case. Here is a quick showing of which ones. The blue case is a charger for two batteries at a time. It also uses the batteries as a power bank when not using the radio. I just realized that you can also power the radio with it using a type C to type C cable.
