Description

Built with LiFePO₄ battery cells for a lifespan of over 10 years, the B80P expansion battery is designed to go the distance. With an IP65 water- and dust-resistant rating and an industry-leading 6-year warranty, it’s built tough for outdoor adventures and reliable enough for everyday backup.
The B80P works perfectly with a wide range of Bluetti power stations - including AC60, AC70, EB55, and AC180 - to dramatically extend capacity via Power Bank Mode. More than just an add-on, the B80P delivers 806Wh of energy and up to 120W DC output through USB-A, USB-C, and a car port. That’s enough to charge a smartphone 43 times, a laptop 10 times, or run a light for 60+ hours - making it a versatile backup battery on its own.
Unlike other packs with limited input, the B80P offers true flexibility. Recharge it directly via AC adapter, solar panels, or car charging, or connect it to a power station for effortless top-ups. Wherever you are, you’ll always have a way to keep your battery full.
