Maximum heat level for batteries inside a van?

[oceanrider]

Just curious about heat inside a van and how it will affect the batteries.

I will be in Southern California, mostly coastal area but the temperature does get to 100f+ degrees occasionally where I am just inland.

When my charcoal gray van is not being used, windows not open and vent not running, it will get pretty hot inside.

What concerns should I have for 48v server rack batteries?

Will this be stored or used? If used, what are internal temps? My car reaches 150 in the sun, which is definitely worst for batteries than 100F.

I live in AZ with temps reaching 115 F in the summer. I keep the battery stored at 50% disconnected in those temps.

For my house, I have the lithium battery in the garage and it reaches temps over 100 F. There will be some degradation. Next summer I plan for the batteries to be Air Conditioned. The air conditioning could cost more than the batteries.

What I'm doing is not optimal with storing the batteries in the garage; 75 F is optimal, but 75 F is not practical either.
