@warcelo 25R cells could work but if you go 4S2P I would rather do it with 21700 cells such as Samsung 40T although they probably don't fit the Solo battery case anymore.
In case you have not opened a Solo battery before: In my experience it is quite difficult to open it clean without a lot of damage. 3D printing a new case would probably be an option.
