there’s a setting for the radio strength between the halves. i‘ve cranked it, cuz i want the halves to be able to communicate through obstacles, but lowering it may improve battery life.

Ergonomic, split and other weird keyboards
Rules
Keep it ergo
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

I'll have to look into that, my two halves are never more than a couple feet apart, and always with LOS, so I should be able to get away with pretty low power.
If you're using zmk, you should investigate the viability of a dongle for your setup: it's a third nice!nano (or other Dev board) that's directly connected to the computer (without battery) and serves as central side while the two parts of the actual keyboards are configured as peripheral.
Since central's energy consumption is massive compared to peripheral's, weeks or even months between charges in this topology isn't unheard of.
