main disadvantages id see from a electronic perspective (still quite new to qoads though)
would be:
- if you use more power for additional stuff, like LED's, theres less power for flying (obviously not huge quantities, but also depends on what you hook up to what)
- also when powering LED's at theyr maximum rating, you diminish theyr life expectancy by quite a bit
if you really want to get funky on something fail safe, you could also think about making a small little circuit to trigger a buzzer or light from a coin cell battery (which would still work when u destroy/loose the lipo)
you would just have to decide on what triggers it reliably, but this might help going in the right direction
