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 ...

The middle charge voltages in LFP are so flat it might be hard to impossible to really know on voltage alone what the charge level is. Generally a capacity test will be run top knee to bottom knee. The whole 50% discharged thing kind of fades away with LFP. It appears to me the charge level indicated by the BMS becomes more important.
it is flater than a normal battery but not that flat, you just need a better resolution voltage meter. every 0.1 seams to be aproximatly 10% so a reading of 0.01 change would be 1%. seams you can get pretty accurate with a deicent meter that is made for Li.
