In my view, the internal battery storage compartment is superior to the alternative, which is some kind of proprietary backpack style lipo.
I find that the FT817/FT818 internal battery storage is much more flexible and diy friendly than alternatives in the amateur radio world.

cells use the correct dimensions as well as having a VERY low self
