I'm having trouble getting my batteries past the 3.35V mark. 4 x 3.23V 272aH LoFePo4 Cells in parallel.
Today I changed my method to the incremental top balance (@3.4, then put psu to 3.5, then to 3.6 etc.) after waiting maybe 4-6 days setting the benchtop powersupply to 3.6V without the batteries moving up.
I came back home tonight to find that the PSU voltage had drifted from 3.4V to 3.35V, so sadly another day wasted where the batteries couldn't creep to balance
I'm growing frustrated and impatient. I hear it is meant to take a long time, but I would like to at least do a capacity test on 4 of the 12 batteries I purchased.
Is there something else I could do? Maybe charge the cells individually to 3.5V and then in parallel?
