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.
@praxeology interested in the stuff that @bce has been releasing lately. But you could also use an MNT reform charging board.

Replacement Battery Boards (protected) for the two battery packs in the MNT Reform laptop.

@liaizon @bce @mntmn I actually looked at that right after I posted. I am tempted to try.
