One user says they only charge their LFPs to 3.4V/cell whereas 3.6V/cell is required for 100%.
Is it not necessary (or advisable) to charge to 3.6V/cell from time to time for passive cell balancing?
If it is advisable, how often? Once a week? Once a month?
(As an aside, would it be reasonable to assume that the majority of solar LFP batteries use passive cell balancing?)
