Introduction

Usable energy capacity is often more important than nominal capacity. LiFePO₄ batteries excel in deep discharge performance, allowing users to access more stored energy safely.

High Depth of Discharge (DoD)

LiFePO₄ batteries can be safely discharged to 80–100% DoD without significantly impacting lifespan, unlike lead-acid batteries that typically require shallow discharge.

Stable Voltage Output

Even at high DoD, LiFePO₄ batteries maintain a stable voltage curve, ensuring reliable operation of inverters and connected loads.

Practical Capacity Advantage

A 100Ah LiFePO₄ battery can deliver nearly all of its rated capacity, whereas a lead-acid battery may only provide 50–60% usable energy.
