Recharging LiFePo from BMS low volt shutdown

[MrNatural22]

What would be considered a safe time limit between the time your BMS shuts your LiFePo battery down with BMS set at 11.2v low volt disconnect at night after using to the time the sunrise begins recharging the battery back up?
I know it’s not a wise practice and can damage a LiFePo sitting at low voltage for a long time.
Does one need to immediately start recharge from shore power with a genny or other source?
Can it sit safely til morning sun?

I would think a few hours would be fine. If you are really concerned consider raising low voltage shutdown value. Personally If I do not need the power I don't want to charge with anything other than solar

@ 11.2V / 2.8v per cell, it's not empty enough to be at a point of danger. For even a few days it shouldn't be bad for the battery as long as it's not freezing or baking. The lower it goes the potential of problems increases.
