Lithium Battery Question
I am thinking about converting my 2020 lance to Lithium batteries. I want to do it as inexpensively as possible. (Battle Born ain't gonna happen) Can anyone tell me what specifications I should look f...

I can’t fathom camping at -40, I picture everything breaking off in my hand and condensation everywhere ;)
At temperatures below -30 C, the relative humidity is pretty low. Condensation is not much of an issue. In fact, I've occasionally used a humidifier.
My peak load for power, in such conditions is 7700 watts (real life measurement). The average load is about 80% of that number. I get to that power level by using a break out box on a 50 amp pedestal and two ancillary shore power cords (oem 30, a 20, and a 15 amp).
To get full power on the 30 amp, I use an autoformer. Why? Because power varies by the square of the voltage. 120 x 120 = 14,400; 100 x 100 = 10,000. That represents a 31% power drop.
The lowest temperature I've actively camped at is -37C. Moving Sue and Photo Mike have camped at -40. I believe they were boondocking (hats off gentlemen, hats off).
I use the propane furnace as a back up. It is set at 16 C as a "fail over" should the power go off. I do have a "magnetic" stick on heater that is small enough to be used from the inverter, to allow the propane to boil if necessary. I've not had to use it, but the propane tank does get some radiant heat from the living quarters of my class C.
However, my storage requirements are -42 C (-43.6 f). There is no shore power source at the storage yard.
