Time2roll,
It is true my rv is modified for cold use. That was the determining factor for the number of house batteries, so I could run a block heater for 3 hours at -40. I have boondocked at -37c (-34 f). Moving Sue and Photomike have me beat--they have both done -40.
One of my modifications is a magnetic block heater for the generator.
But -20 (-4 f) is quite common where I live.
Again Li are super batteries when full time, or no low temperatures.
And the thread is about float values of LFP.
Best to start a new thread about low temperatures and the effect on batteries etc.
