Does anyone know of a powerbank that has replaceable LiFePO4 batteries? I'd like to find something that's less disposable.
@praxeology there are lots, but even cooler would be some OSHW USB C charging circuits that you can put into a box with some batteries.
@liaizon I found some that have LiFePO4 batteries but they don't appear to be user-serviceable. Can you point to one that is?
@liaizon But I'm basically hoping to find something like what you describe.
