BLUETTI B230 Expansion Battery | 2,048Wh (Refurbished)

Power up your Bluetti system with the B230 Expansion Battery, delivering 2,048Wh of additional capacity in a compact, refurbishment-grade pack. This expansion module is designed to plug into compatible Bluetti power stations, instantly lengthening runtimes for off-grid stays, weekend camping, or home backup during outages. Each unit has been professionally inspected and refurbished to maximise performance while offering a more sustainable option. The B230 features a robust battery management system (BMS) that guards against overcharge, short circuits, and overheating, helping protect your devices and the battery itself. Lightweight enough to transport for outdoor trips, it enables staged charging from solar panels or mains, and when paired with your main unit, it unlocks extended power availability for laptops, phones, tools, and essential appliances.
