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 ...

10.000 volts is considered flat dead and well into the lower knee that commonly would not be used. Going to drop fast from 12.0 to 10.0 volts as there is not much energy here. Energy and voltage is not linear but rather an exponential curve at these points.
This is true for all sizes of LFP batteries. You can have one or one-thousand in parallel and it is still 10.0 volts. 10 Ah cell or 310 Ah cell same thing at 2.5v per cell and there are 4 series cells in a LFP battery. The BMS will cut power based upon the lowest cell hitting 2.5 volts so power could be cut before 10.0 volts. But again there is no real reason to go below 12.0 volts except to prepare for system shut down.
I was going to bring that up but his mind is spinning don't blow it up.
