Unfortunately, this is a fairly standard mod for me so I didn't document it rigorously - I may add additional capacity in the future and will keep in mind to take more photos then. Feel free to ask specific details and I will do my best to describe them.
The battery was a random one I had in my collection of salvaged LiPos - model number PP045582AB - google says the dimensions are 137*45*4.1mm.
LiPos come in a variety of dimensions and depending on whether or not you are willing to cut away more of the plastic frame, you likely can fit larger ones as desired. The primary constraint is the narrowing of the enclosure towards the trackpad edge.
Personally, I wanted to keep all four screw-holes on the plastic frame intact as well as not obstructing the NVME mounting area.
Updated energy consumption statistics after one charge cycle since the mod.
