LiFePO4 - SOK or Renogy.
Not looking for a big bank or high charge/discharge currents. Don't need charging below freezing. In Canada things become difficult/expensive. Narrowed down to these 2: 1)SOK, 100AH, $CAD 975 ...

Solar generator is an overpriced combo of Li battery and inverter, $CAD 1,400 for 1,000 WH. I paid $CAD 800 for 1,500 WH, i.e. 3 times cheaper per KWH. With a single 1,000-1,500WH battery you don't want a big inverter, nice 300-400W PSU inverter would cost less than $CAD 300 and I already had one.
It does take 200-300W solar to keep it topped up, but for a weekend with modest loads you just discharge battery down to zero and go home. (Actually down to DOD 20% in my case, since it's 120 AH marketed as 100 AH). What I particularly like is 30 lbs weight - much better than 70 lbs FLA or AGM of the same nominal capacity (not to mention 2 times less of usable charge).
Our needs are modest. The CPAP will run on 12 V DC and consume roughly 12Ah per night.
We currently have 100W of solar, a PWM solar charge controller and a 100Ah FLA battery.
We just paid for our new rig so funds are stretched, I’d like to start small - maybe a single 100Ah LiFePO4 this year. Next year I hope to add 200W of solar, an MPPT charge controller and another 100Ah of storage capacity.
The SOK won’t fit. The reviews of Renogy are discouraging. That leaves Lynac, Volthium and Canbat. Lynac’s True Power line is probably the best deal because, as you say, it’s 120Ah.
