Bluetti Expansion Battery B-Series / Maximum Autonomy Through Additional Capacity
The Bluetti B-series expansion batteries (e.g. B80, B300, B500) are the power boosters for your Bluetti power stations. They significantly increase the total capacity of your energy system, enable longer runtimes, and some models even offer independent charging and discharging functions. They are essential for modular Bluetti AC inverters.
Highlights
- Extreme Cycle Life: LiFePO4 cells guarantee a lifespan of 3,000+ to 4,000+ cycles.
- Modular and Scalable: Allows for flexible adjustment of total capacity to specific energy needs.
- Usable Independently (depending on model): Some B-series batteries have their own DC ports and can function as a power bank.
- Robust Construction: (e.g. IP65 protection for the B80) for use under various conditions.
