It'd be nice if lead-acid could see some progress on the deep-discharge durability front. AIUI whenever people currently size lead-acid PV systems for boats/RVs/homes they basically get double the battery capacity they intend to use to preserve the batteries. That really sucks, and oftentimes they still end up accidentally damaging the batteries due to a long outage or other oversight/circumstances.

Having said that, LiIon isn't that good at surviving deep discharge either, although it is better than lead-acid. A battery management system can be used on both, which will turn off the power when there's still some juice left, to protect the battery, but people only ever seem to attach these to LiIon batteries.
