Record decision to keep 48.0V discharge floor (improvement #3)

Reviewed the cutoff/stop-discharge floor; deliberately kept at 48.0V (3.00
V/cell) for cycle-life margin. Lowering to 46-47V unlocks only a few % of LFP
capacity and isn't worth deeper cycling on this large, non-capacity-constrained
bank. Comment only; no value change.
