I have two sets of BYD 13.8s with a 15000 Quattro and today have noticed the state of health of the batteries at only 66%. This is not a figure a looked at before but with the batteries being only 7 months old is there anything I should be doing to get them back to 100%?
I have solar and a generator to charge them. They were charging at the time I took these screenshots, initially at about 5kw (first pic) then higher current 10.7kw.
