Lithium batteries and new solar charger
I am replacing my 4 6V batteries I think 2 lithium, have never been impressed by the 30A PWM charger for my 600W solar, probably my fault for using 8 avg wire on a 9m run. Thinking if I get a Victron ...

Your two 100 LFP will actually have 80 usable each so 160 not 200 to compare with the 260. (you don't normally go below about 20% DOD)
Your controller is a 12/24 but being PWM that only means 24 if the batteries are also 24. To go 24 panel and 12 battery, you must have an MPPT with its buck converter that PWMs don't have.
Depends on whether the batteries are 'true' AH or not. The last LiFePo4 battery I bought was rated as usable 100AH, so in reality 120AH.
