Hello, just installed a SOK 12v 100amph LIFEPO4 battery in my trailer. when I left yesterday (storage lot) the battery was around 13.5v. I went this morning to do some work on the trailer, temp was 26 degrees, battery voltage was 12.6v. No loads, just the 25-30ma that the Victron 100|20 takes. Once the trailer warmed up, the voltage went back to around 13.3v, I disabled the controller, wanted to see if the voltage would jump back on it's own. I also know that charging a cold LIFEPO4 is super bad, I have the temp cutoff at 5 degrees C. My question, is the low voltage normal when it is this cold, with no loads?
