I have a decision to make on where to place my LFP battery pack.
I have two choices.
1. Ground level of the unheated building. It gets warm (35C) in the summer and cold (less than zero) in the winter. My Victron setup, PV inverter and generator will be in here.
2. Underground cellar of the same building. In the winter temperature does not ever go below 7C and in the summer never goes above 15C. The only problem in the summer is humidity getting up to 85%.
Option 2 looks ok for temperature but would the humidity be a problem for the batteries?
