5 Amperes is excessive i.m.o.
3 Amperes is still okay for a 219C, maybe 3.5 Amperes.
But with a linear driver you run into problems when the battery can not provide the Vf at such currents.
The party is over pretty soon, even with modern low Vf LEDs.
DD FET drivers and how they’re usually implemented makes matters even worse.
Folks are limiting the current by means of thin wires and what not…
Sure, that’s what you would want when the battery is fully charged, but that’s only a short while…
