I was going to accommodate for one of my mini voltage readout screens and had thought about adding a small rocker switch already. Will share what I end up making!Be aware that drone lipos probably don't have an over discharge protection circuit, the Heltec will drain unprotected batteries completely and permanently damage them. The ones I linked to above have a protection circuit which will disconnect the battery when it is as low as it can safely be discharged
I will add a "deep sleep" command (it will reduce current consumption to almost 0) to the menu but you might want a mechanical on-off switch too
