RE: For BFL13 et al... FLA vs AGM vs Li vs heated Li
Thanks for the discussion! And, considering:
https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/
and the above comments, here is what I got out of it...:
Should not charge/discharge LPF's below 32Fand should not consider charge/discharge above 113F.
So now BB has self-heating LPF’s that will over-count charging AH/WH on a shunted battery monitor. Do you think BB will also add a chiller to the BMS to keep the batts less than ~110F and do the same for a shunted battery monitor? 1 or both will add another parasitic drain.
And thus, its back to using a VM to guesstimate SOC.
I’m going to start calling LPF’s the “fair weather batts” because using them during many summer and winter situations without heating and cooling will make them limited if not just useless.
This makes the all(most)-weather capability with a weight penalty and lower cycle-life of FLA, AGM & SiO2 batts most attractive.
And, you might outlive a set. YMMV.

RE: What's the Latest Solar Tech?
Here are the major components for a 12v system (not MPPT) that would satisfy your group 27 batt and it is easily upgradable for more batt AH as what BFL13 mentioned for 220 AH (just add an identical second panel) :

RE: Anyone use a Solo Stove
I've been using the Solo's competitor for a decade when backpacking, etc.:
Silverfire Scout
For the trailer, its the:
Survivor Rocket Stove
Both are near smokeless after startup.
