Where do you buy a battery for a jbl Charge 4 ??
Probably just cut open the blue foil around the batteries and replace them by re-soldering the electronics onto new 18650 batteries.
correct me if I’m wrong here.
If you know how to handle them and have experience with soldering them that's a yes if not those batteries are really dangerous if you don't know how to do it correctly.
