95g, USB-C rechargeable up to 85 days of operation, separate control and charging boards, multiple replaceable components for easy maintenance.
Probably lots of ways to free up space, most notably by using a smaller battery but with a few resources you could probably combine the boards and probably not even be obvious ("generation 2, less expensive to produce"). With state-actor level resources new boards would be easy as would something concealed within a LiPo battery.
