For those with space available (per my solution, repurposing batt box for other storage?), mounting LFP’s inside in a under-dinette cabinet space have solve my 32f charging concerns…

personaly I think 32 was chosen because of lack of knowledge and a carry over from other Li chemistry.
Two of the largest manufacturers, EVE and CATL, give 0c as the minimum to charge.
Ignore factory specifications at your own risk.


I just went and checked because they were the ones that used to be listed at -5C and there was a big discusion about it on here. seems there page has changed since I ordered my cells. oh well no biggy mine would never be subjected to charging at cold temps anyways but ya it is interesting for the OP now. I wonder if he can post a screen shot of all the settings.

I personally enjoy seeing the screen shots of different battery makers and there specs like Trojans new LFP, I had not seen(interesting)..I never thought for a minute it was irritating to some..Lesson learned and duly noted...

Thanks for the heads up
