Product details
The BLUETTI B300S is a high-capacity, LiFePO₄ modular battery pack made to work with the AC500 inverter. It’s built to scale your power system: you can add multiple B300S units to increase your total energy storage. Even though it’s mainly designed as a battery module, it’s versatile enough to power smaller devices by itself through its built-in DC outputs.
This battery is very durable: thanks to its LiFePO₄ chemistry, it has a very long life and supports thousands of charge cycles. It also has a self‑heating function so it can operate efficiently in cold temperatures. With its MPPT-based charge system, you can recharge it using AC, solar, or even a car, making it flexible for both off-grid and backup power solutions.
