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 OP says he is getting two 100AH LFPs with usable of 200AH if he runs them down, but he has indicated he knows to run them down to 20% normally, and make his usable 160AH vs whatever his four 6s have for usable. depends on the AH size of the 6s. Some are 190AH, some are 210AH mine are 230AH, some are more. the OP said he could get more like the same usable with three LFPs that way.
Just to make more trouble :) The OP says his batts are rated at 1280 Watt hrs, which is from 100AH x 12.8 v (their "nominal" voltage)
But resting full is 13.6v so 100 x 13.6 =1360 watt hrs so it is confusing? Whatever, Battle Born claims the 100AH batt has "2 to 3 times the power of the same size lead acid" batt.
"Power" meaning watts? Watt hrs? meanwhile a 100 AH 12v FLA has a resting voltage of 12.73 when full so that is 1273 watt hrs.
Beats me how 1360 is 2 to 3 times 1273. I am told this would all make sense if only I owned LFPs myself, but do you need some kind of New Math too? :)
