Optimal compromise for LiFEPo4

Yes

I wanted wingnut to answer, but since you answered, what can/will 60°C do to a battery ?

 

[wingnut771]

Does temperature affect discharge, even if battery is not in use ?

Yes it does, refer to pic.

High temp is bad for most things in life. I guess it will shorten it's life in a high temp environment. Why do tesla batteries last longer than nissan leaf batteries? Tesla has active cooling, leaf doesn't.

Science 101

All batteries deteriorate due to chemical reactions, heat simply increase rate of any reaction

Well then you wanted to know why batteries get delivered to you with around 50% SOC .

When they come via sea freight... those containers temps rise to as high as 60°C , and sometimes higher.

If the supplier and local distributor don't worry about these things (like loading into reefers) then expect a sub-standard product.

It was all rhetorical

I do think Lithium follow a strict rule when shipped. I know for one you cant simply ship lithium related goods without declaring it.

Pretty sure those goods get packed at deck level to watch temp and not on top of the stack. Esp seeing that a lithium fire + water = boom

Ok.

Shipping is my game , you don't know what tricks importers use to get their product in.

Hmmm, I had 3 batches of Pylons in the last few months and they were all around 70% SOC when they got here.

Is @wingnut771 the local battery guru or something?

why don't you ask him

 

[Vorastra]

I tagged him in the comment for that exact reason.

No, just your local unemployed middle aged white boy that's having a midlife crisis that has a lot of time on his hands.
