LIB-902 to 1S li-po adapter

thingiverse

Here's the adapter that lets you swap out your original LIB-902 battery in your Aiwa minidisc device for a ZOP Power 600mAh 1S battery found at https://www.banggood.com/ZOP-Power-3_7V-600mAh-20C-Lipo-Battery-JST-Plug-p-994143.html. **WARNING**: To build this adapter, you'll need to modify the battery by removing its top layer of fiber tape and soldering wires onto it. You do this at your own risk. To assemble the adapter, replace the negative wire with a longer one and be careful not to poke the battery packet when tucking the negative wire into the groove inside the wall using thin tweezers or a similar tool.
