We do it at https://infinite-battery.com :) our battery is compatible with Gen2/Gen3/Gen4 (we haven't yet tested on smart systems though)

I started doing some research over the holidays and the smart system seems to be designed to prevent reversing - fuses blown both ways, so didn't even manage to read the firmware, and communication with the client software relies on what seems to be decent encryption. And from the design of the hardware bypasses it seems that the firmware does not trust its own peripheries. Good design, no doubt - will try to take it apart when i switch bikes and won't mind bricking my unit.
