Alright speaking of shorting, I have an order on the way now for a shorting machine to further investigate this:
Key design goals:
- External backplate expanded to store two additional batteries
- 3 slot gap created between those two batteries allowing a wire to reach both of them hopefully
- The two batteries are both held in place by the same mechanism as the original Librem 5 battery, namely two tabs at the top and the tape to pull the battery outward from where it sits
- As a result of the above, coupled with the desire to put all “positive” terminals and all “negative” terminals together in one place for easy wiring, it is thus the case that one of the batteries loads from the inside and the other loads externally
- The externally loaded battery has a removable door with a design inspired by my GameBoy in the hopes that it will clip on and off more readily in case it’s ever useful to swap the “outer” battery
- If desired, there is a space to screw the Big Battery House into the Librem 5 itself using longer screws and the pre-existing screw holes on the chassis, so that if the 3D print does not fit perfectly we’ll screw it in
- As well as the clippable "GameBoy” door on the back, there is a third component that serves as a spacer which can replace the interior primary battery of the Librem 5 and hopefully leave room for wiring around it and up to the 3 slots for the two exterior batteries, in part because:
- They do not align their terminals exactly to the location of the original Librem 5 battery, and need about 8 millimeters of a wire to bridge the gap and wire them in
- Fitting an extremely flat or thin wire between the internal battery and its terminals to allow two more to wire in might be wishful thinking, so it may be easier to have a 2 battery solution instead of a 3 battery solution
I’m hopeful that by throwing the kitchen sink of ideas at this project, even if some parts of the resulting design fail perhaps enough will work that it will result in a useful product.
Edit:
Was able to render the complete assembly and how this is predicted to look. Image shown below:
