For BFL13 et al... FLA vs AGM vs Li vs heated Li

“Should not charge/discharge below 32F”.

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??
