Lithium Battery Storage AZ Heat

[cactusjuice]

I’ve been researching and researching and I cannot find a definitive answer. Perhaps someone can chime in with a little knowledge and/or first hand experience.

I am wanting to upgrade to a lithium battery set up with solar. Question I cannot seem to find is about storage and longevity of the LiPo batteries in the Arizona heat. Summer time temps get up to 115 during the day and sometimes do not drop below 100 at night.

I plan on using the trailer about once a month or so during summer but due to work I may not be able to use for a month or two. Trailer will be stored outside with no cover. Should I be concerned about leaving the batteries in and charging in such extreme heat? I know the specs on use and storage for various BMS but will it harm my premium investment to leave them in the battery box, in full sun, connected to solar to keep them charged? It can get pretty darn hot in direct sunlight.

Thoughts? I know I can pull the batteries and move them inside the house but sometimes we just want to get up and go at a moments notice when the opportunity arises. Thank you all in advance - any input is appreciated.

My Renogy Bluetooth battery recommends max charge temp on 131 and discharge of 140 degrees. I moved mine inside away from theft, lighten tongue, out of the weather and nearer MPPT. If it is 130 degrees in my camper I won't be in there or using power.

Does this help? at 27 pounds, you could pull it and store it inside your house.
