I know the Rotax has a limited alternator if only using the one supplied.

Is there a problem using a landing light for 5 minutes even if if that would
be discharging the battery by 5 amps?

I had a 1948 cessna 170 that had only a 25 amp generator. When lights were on
it discharged. Unless at cruise power, the generator did not put out.

Used it for 19 years, never got stuck with a dead battery. Just used lights
when needed.

A 5 amp discharge on a 16 amp battery should yield over 2 hours, no?

If using 914, with 1 alternator, and battery failed, unless you turned off
some loads the fuel pump would quit or run slow. So you turn off load.

Is there some sort of rule in aviation electron flow that states you can't
overdraw what charger can put out?

Heck, with the Turbo you are limited how much time you can add to Entropy at
full power, so you limit a negative electron flow so you don't exercise
battery by doing deep discharge too much?

I have a sealed lead acid battery, think it is 5 amps and it is not a deep
cycle battery. I use it for charging electric models at ~ 2amps for portable
field charger. have used it for years, still works fine.

If I don't know enough to know how little I know, please beat me up.
