BLUETTI B300S 3,072Wh Expansion Battery
Equipment Type and Primary Applications
The BLUETTI B300S is a 3,072Wh high-density lithium iron phosphate (LiFePO4) expansion battery designed to increase stored energy for compatible BLUETTI power systems. Applications include residential standby power augmentation, recreational vehicle electrical upgrades, remote work-site energy reserves, and modular hybrid inverter microgrids.
Performance Specifications
- Rated energy capacity: 3,072Wh.
- Battery chemistry: LiFePO4, with cycle endurance beyond 3,500 full depth-of-discharge intervals.
- Standalone outputs: one 100W USB-C port, one 12V/10A accessory socket, and a secondary USB-A interface.
- Charging pathways: direct AC mains input, photovoltaic array coupling, or 12V DC vehicle charging.
- Output regulation: continuous DC stabilization for sensitive electronics and resistive appliance start-up loads.
- Maximum clustered storage: 18,432Wh when fully paralleled with primary AC500 hardware units.
Safety Features and Certifications
- LiFePO4 cell chemistry provides stable thermal discharge profiles.
Installation and Maintenance Requirements
- For system expansion, use the proprietary pairing architecture with BLUETTI AC500 all-in-one hybrid inverter platforms.
- The dedicated synchronization bus aligns charge distribution and enables state-of-charge tracking without external monitoring hardware.
- Independent low-voltage loads can operate when the B300S is deployed as a standalone unit.
