See an aircraft mechanic who will ...
install a legal anti-collision light (LED strobe uses the
least power)
fabricate a proper battery box for a battery,
perhaps install a voltmeter,
fabricate an electrical bus, circuit breaker and switch,
perhaps an external power connection for charging,
do the weight and balance and update the paperwork and
aircraft logs.

The airplane may have had an external wind-driven generator
originally, you could restore that with a modern alternator
at the cost of a 1 or 2 mph.




But with a "modern alternator" you now have an engine driven electrical
system, and all of the requirements that go along with it...
(transponder within mode c veil).

I would do the battery thing and/or investigate the wind generator.
