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 ...

If the battery is rated 100 Ah it is just 100 Ah.... not 120 Ah.
If you get more fine but why are you expecting 120?
Because so many are saying they are really 120 not 100. If 10v is zero, then it can't be true.
The story has been that they make "zero" above the real zero so you can run the batts down 100AH and not get to the real zero. So the fake zero would not be 10v, it would be 12v.
It would not matter except apparently some LFPs don't use a fake zero. In that case the voltage/SOC for the fake zero AH batt would be different from the LFP's that uses a real zero.
If you are setting your low as you dare to go operating limit using a voltage setting that is supposed to represent the SOC you picked, it would be useful (!) to have the right voltage for that!
