Wrong, in most cases LiFePo4’s can be discharged to about -4f, (e.g. BB, et al) and can be charged below 32f, but at a much reduced amperage. Though my LFP is interior mounted (by a repurposed battery box), in many cases one should be able to do this passively via solar due to seasonally reduced winter harvest.

3 tons the quote from the article qualifies itself:

"Keep battery temperature above 0 C (32 f) when discharging if possible"

I agree with the -4 f (-20 c)

I don't know why the seller's site is so negative about LiFePo4. It would seem to be bad for business. I do wonder if it is a "wiggle" on warranty??

they probably make more profit off the other types. I have hit this in stores with other products where they steer you towards there biggest margin brands or types of objects and make the lower margin ones seam inferior. the other comon problem I run into is the old store owner that hasnt kept up with technology and cant believe anything new would be better than what they have been using for 80 years... ;)
