Odds are they’re using an RTG to power it anyways. Titan actually has a much thicker atmosphere than even earth and it’s much farther away from the sun as well so solar isn’t going to be a good option to power anything they send down.
RTG would need batteries to be getting charged to meet power demands of flight, but I guess that should take care of the batteries being kept warm enough.
