I’m using 8x 100ah winston prismatic cells. With the. 123SmartBMS looking after them.
We’ve had a -10 night so far but thankfully the inside of the trailer stayed just above zero. I have the batter located between the two 70l water tanks so when they are full it takes quite a bit of cold to drop them to feeezing point. Which then of course I have two problems!My Rev Power battery certainly does not like being cold for very long.
Took this photo on a frosty winter morning where the overnight temp was sub zero but nothing like -10 or -20. Apologies for the glare, but the message reads "Output battery under temperature fault".
The battery happily came back to life after the cab warmed up but the warning I took from this was if camping in wintery conditions make sure the battery is reasonably insulated and be vigilant that both charge and supply may be interrupted if it is too cold.

If it was that bad of times is put the gas heater underneathIf you have the battery power, I'd get one of those 12v heated blankets and wrap them around your water tanks, wack them on a temp switch and have them come on just above freezing, even have them on a voltage sensing relay so then cut off before eating too much power but if you are out of power and it's still below freezing, bad times.
Easier said than done atm. I’m currently on a farm in Iran where solar panels aren’t so popular due to very low electric prices.Get some solar panels, then you can offset the heat with the power generation.
