heat and Li batteries.

[pianotuna]

Hi Folks,

I hope this is of use.

It may behoove folks in such hot areas to provide cooling for their battery bank--either by having it in the living quarters (which I'm personally loath to do), or by some other method of cooling.

Ole ‘tuna, does it ever get tiring stirring that pot?

Where’s the like button? Cause you get one for this post!

Thanks for informing us that all lithium ion batteries are the same thing…

When it was strongly implied that they are "diiiiiiiferent" earlier in the thread, seems like a useful point to make.

While they all have "lithium" the chemistry of batteries typically found in portable electronics and that found in electric cars (and used in RV's) are not only very different but also have different operating (and danger!) characteristics.

While not exactly 'apples vs oranges' it is not 'apples vs apples' ether.

yes, but it's the chemical composition that controls the properties. LFP batteries have a wider range than what is used in cars.

it was 46C here yesterday and my LFP batter in the camper didn't spontaneously combust.

Lithium ION as previously pointed out. True.
But how many truck campers have Lithium ION batteries?

Lithium Iron Phosphate, according to the manufacturer's information have a working temperature between 32 and 130 degrees as I recall.

Yesterday:

Still plenty of room to move. . .

The excessive heat shortens the life of all batteries. Not unique to lithium of which others may suffer even more.

[ScottG]

Optimum upper temp is 113 degrees but they are fine and perfectly safe up to 140+. Also, every one I've seen has high temp cut-off.
At any rate, if it's that hot, we've got more serious issues.
