[QUOTE="Bob Smith, post: 537367, member: 35176"] Thanks [USER=35807]@arwooldridge[/USER] Generally, all batteries are affected by ambient temperature. This is why I gave up the idea to put everything outside ( I had a nice corner out of the view and not taking place in my attic) despite some brands saying they can be installed outdoors. Of course, they will have a cover to protect them but they will be more affected by the temperature than those insides. Unless you have a pack with a heating system (I seem to have read that Tesla has this). So as you pointed out the real question is Are the HV batteries more affected by the low and high temperatures than the LV? It is very difficult to get any data from the manufacturers. It is like trying to get the SoC at end of life. I only know Sunsynk provides that info on their datasheet. (quite bad 40% SoC at 10y) once [USER=35153]@johnb2713[/USER] shared a chart for the EEV cells . That is I would love to see charts for: [LIST] [*]Loss vs time at rest [*]Efficiency (power charge) vs temperature [*]Loss vs time (during everyday use) [/LIST] [/QUOTE]
