I desperately want to convert our small off grid hunting cabin solar system from AGM to LifePO4. However, I am getting conflicting information about these batteries being STORED for months at a time in sub freezing temperatures.
Yes, I know this it is not ideal to store them in cold weather but that is the reality of my situation. It is impractical to remove the batteries, for instance, in December and re-install in May. We have members that use the cabin sometimes in January or even February and they use the lights etc. If I were to remove the batteries as recommended I would soon be told to replace them with the old AGM's.
So, can I store them in very cold weather without hurting them or not? I know they should never be charged at these temperatures and that is not problem with the right BMS. I am strictly/asking about cold storage and potential damage to the cells.
Appreciate any experience anyone might have in this regard or any scientific papers that might address this issue.
I am aware of different heating elements etc. but I am not too thrilled about leaving any "heating" device for months at a time in a location that is not monitored frequently.
