You could even get some COB leds than are 3-4 Volt and use a tiny 1S battery to power them.
I have a tiny strobe LED module from FLYTRON that is visible for 2-3 miles at night. It runs off a 1S battery about the size of a quarter, I have let it run to see how long the battery will last, after around 24 hours I cut it off. But of course a constant on state would be a fraction of that, but I am sure it will last for two or more flights. If not you can have spare batteries and swap them out when you swap out the P3 battery. 1S batteries are literally five for $10.
I have drawers full of all kinds or lipos and leds, led strips, led strobes, multi color leds, i should put something together. But ehhhh
