I am thinking of just adding some wiring to an external battery.
I wonder if it might make sense to replace it by a capacitor. For this kind of
application, the total capacity is not an issue at all, but only the available current for
a fraction of a second. By that measure, it doesn't take all that large a capacitor
to do as well as a battery; the difference is that the battery can sustain that current
far longer -- which doesn't matter here.
