Solar batteries often fail while showing 60% charge. Learn why passive balancing BMS causes hidden capacity loss in high-discharge LiFePO₄ systems.

Float charging accelerates lithium battery aging by 20-30%. Why lithium doesn't need float, calendar aging mechanisms, and configuration to maximize lifespan.

Introduction A lithium battery that “won’t charge past 85–90%” is one of the most common complaints installers and system owners report. The system shows adequate solar input, the charger reaches its configured absorption voltage, and yet usable capacity appears to…

Introduction What “Bulk” Actually Means for Lithium We established in our previous post that lithium battery uses two-stage CC/CV charging, not three-stage bulk The “bulk” label is legacy terminology from lead-acid systems. For lead-acid, bulk means pushing high current through…

Discover why lithium batteries don’t need bulk, absorption, or float stages and how using a lead-acid framework can reduce battery life by years. Essential reading for lithium installers.
Why solar-battery systems fail after 18–24 months. A technical breakdown of inverter, BMS, MPPT, and thermal integration failures installers overlook.
