Not at -30 to -40.
I bet your home is above 5c when it hits -40. Suddenly a little battery can't be kept warm?
Maybe a bit more effort but come on.

Question: So to be intellectually honest, -30 to -40 (though possible) should be viewed by most as an outlier scenario - Are we now suddenly to believe that as thinking beings we’re devoid of ingenuity, creativity and resourcefulness, else we perish of malfeasance ??...To overcome the dreaded contagion of mental paralysis, how about this just for starters:

a) insulated battery box
b) electric heating strip
c) interior mounting (beneath dinette seat??...worries gone!!)
d) be sensible and migrate to a warmer climate
e) SiO2 as an alternative to counter (uninsulated) extreme WX??
F) demand that the nanny-state tax your neighbor to subsidize your battery requirements (a standard fair green subsidy thingy - lol )

The point is, where there’s a will there’s a way, eh?? Geeze!!...time now to take some personal responsibility, “Improvise, Adapt and Overcome” your issues...

Tomorrow is not today. I deal in today. I don't need a Versachi suit to impress myself. A lithium battery bank is justified for long runs of deep cycling use. What is the percentage of RVers that camp longer than a week off grid? Trying to convince a weekend warrior that a lithium bank is justified is like trying to convince a deer hunter an RPG is indispensable. Remember a pessimists glass is half empty N optimist's glass is half full. AN ENGINEER figures out the glass is twice as big as it needs to be.

3 tons,

I am your outlier.

Nice list, but I won't put any "house" battery inside my living quarters. I'll have to work as long as I can, so going south is not feasible.

Mex, I need to run an O2 concentrator overnight without a generator running. I can do this on 7.2 kwh of battery bank. SiO2 meets my needs for extreme cold. So do Li Titinate. I moved to AGM because I did not enjoy laying in the snow to service the 875 amp-hour flooded battery bank.


Regards, Don
My ride is a 28 foot Class C, 256 watts solar, soon to have SiO2 batteries, 3000 watt Magnum hybrid inverter, Sola Basic Autoformer, Microair Easy Start.

Battery choice (Uh, choice is good right??) should be a cogent determination best made by ‘thinking individuals’ rather than non-sentient zombies (e.g. your referenced Moo-cows...)...Admittedly, this culls the herd considerably - and those remaining are often a minority of individuals who choose to plan ahead and possess the ability to see beyond the trendy slogans of bumper stickers...

I would also note the ‘perceived infallibility’ of those poor Morton-Thiokol ‘engineer-experts’ who made the failed O-ring selection, and final launch call for the Challenger shuttle...This example highlights why one should avoid the temptation of outsourcing their own *critical thinking’ skills...

*(e.g. discounting the vagaries of non-user ‘opinion polls’...)

I find being a Cynic works because in this way I’m never disappointed...

Wouldn't an engineer specify the highest performing battery, then go check with accounting as to whether it is within budget?

Now that the pricing is close to equivalent (or soon will be), why wouldn't you want a lighter, faster charging, longer lasting battery for the same money? Just because it is too fancy?

Per PT: “ Nice list, but I won't put any "house" battery inside my living quarters.”

So do you keep your computer outside?? [emoticon] (lol!)...Note too, when considering danger, what is more dangerous, a non-venting LFP battery (non-hazardous’ during shipment), or multiple interior housed propane appliances subject to the duress of road vibration?? Truth is we cannot escape our very dangerous world...JMHO

I did not realize Versace suit was the same price as Men's Warehouse.

Though it’s taken a bit effort, I think this and other Lithium threads continue to be productive in flushing out subjective FLP mythologies from informed user experiences [emoticon] ,
This, where ‘little guy’ making his on cogent assessment trumps the elitism of the pseudo-specialist...
