There's some internal battery tear-down videos but I've not seen an external one.

Are there electronics inside an external di2 battery ? I know that there are electronics inside the mounting unit, but I'm wondering if the battery itself is simply 2 cells connected in series or if it's something more complex.
I'd like to build a cheap internal battery with 18650 cells but I need the electronics to get it to work.
