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 ...

How much cheaper would it be to build your own? Roughly what would it cost to get the equivalent of 2 6v GC batteries say about 230 ah's?
280Ah is probably the closest 'standard' LiFePO4 cell size. For that you are looking at $600 - $700 for the cells, another $60 - $120 for the BMS and maybe $100 for wiring equipment and some sort of case. I would guess $750 - $900 all up, cheaper if you are wiling to go with Alibaba and wait on freight, more expensive if you want it shipped from the US (amazon or ebay).
This would give you ~3000 cycles at 100% DOD so about 10x the usable Ah than lead acid over the life or the battery (if you plan to use it heavily or keep it a long time).
