Venting Batteries in 5er Basement?
Our new-to-us 5er has one group 24 battery in a front side compartment with the hydraulics for the slide mechanisms. It's in a vented box with a hose that exits the front of the camper. In our pr...

The negative comments were related to the battery in my link above....if I went lithium, these would be the ones in my budget range, and were dismissed as having inferior/unreliable BMS software.
BurbMan,
Nothing wrong with Li until 0 C (32 f). Then dendrites may easily form.
There is one Li subset called Lithium Titinate that can be used in the cold. I got a quote for a single 100 amp-hour jar. It was a mere $1890.00 (cdn).
Here are the "straight good" from an Li seller:
https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/
The highlights from the above are:
"To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:
Keep the battery temperature under 45 C (113 f) (under 30C if possible (86 f)) – This is by far the most important!
Keep charge and discharge currents under 0.5C (0.2C preferred)
Keep battery temperature above 0 C (32 f) when discharging if possible
– This, and everything below, is nowhere near as important as the first two
Do not cycle below 10% – 15% SOC unless you really need to
Do not float the battery at 100% SOC if possible
Do not charge to 100% SOC if you do not need it"
