you have there Vol Cell RFV on 3.350 but on the comments above it says: but set RCF and RFV to almost identical (3.45 and 3.44 respectively) (*)
I had before 3.350 but floating was lasting for only max 10-15 min. now with 3.44 it hold for hours.
But its not ideal, keeping the battery on top most of the sunny day. Still charging discharing all the time. dont have a shunt yet.
