Battery Life?
Newbie here. I've never boon-docked before, and was wondering how long I can have the lights on in my TT before the battery gets to a critical level (from what I've read below half way charged is bad...

For you folks that know about this stuff, what is the lowest that you should ever let a battery be discharged to? Before permanent severe damage is done?That differs by type of battery and construction. Typically, a dealer will equip a trailer with an inexpensive 12V marine-starting hybrid, many of them are BCI GRP24. This type of battery will last longer if never drawn down below 50%. A 12V FLA auto battery will fare even worse. Draw it down below 50% a few times and it will be very limited in capacity or toast. 12V AGM batteries fare better from high draw but the 50% rule of thumb is best. Two 6V in series connection will fare the best of high draw down because the cells are constructed better than typical 12V batteries.
Lithium batteries can be drawn down to 10% of their operational capacity but if allowed to go lower, may not survive.
Summary: 50%
