Battery System Deep Dive: Understanding the 12288Wh Capacity
The heart of the Bluetti AC500 system lies in its modular battery architecture. Each B300S battery pack contains premium LiFePO4 cells that deliver 3,072Wh of usable capacity. When configured with four B300S units, the system achieves the impressive 12,288Wh capacity that makes it suitable for extended outages and off-grid applications.
LiFePO4 (Lithium Iron Phosphate) chemistry was chosen for its superior safety profile and longevity. Unlike traditional lithium-ion batteries, LiFePO4 cells are thermally stable and have a much lower risk of thermal runaway, making them ideal for home installations.
