From f1128e807a8c59a8c834044242566eaca7d6cd11 Mon Sep 17 00:00:00 2001 From: noise Date: Wed, 24 Jun 2026 12:28:44 -0400 Subject: [PATCH] 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.
