given prior discussions of external batteries and framework, as well as my previous post about reusing a lenovo keyboard with a framework mainboard, i’m curious if there’s a way to potentially reuse the batteries from that laptop.
Unlike much older laptops i have owned that used 18650 cells internally, the internal and external batteries in my old T580 dont seem to have the dimensions and I suspect may be custom. I’d like to see if its possible to put them in a new enclosure with some circuitry to replace any battery safety/handling stuff that would have happened on the mainboard of the computer and add some simple indicators and/or ports for charging - i.e. USB-C PD.
basic internet research doesnt seem to suggest many similar projects. the closest i could find is a greatscott video which seems pretty close except imagine using the flat style batteries like those in this ifixit guide instead of 18650’s
