Bluetti B80P Expension battery 70P | Shipped in 1 - 2 work days

The Bluetti B80 Expansion Battery is a compact, high-performance power module designed to extend the capacity of your Bluetti system. Built with the same LiFePO4 battery technology found in Bluetti’s larger stations, it delivers 806Wh of reliable, clean energy that’s ideal for camping, overlanding, or emergency backup.

With over 3,000 charge cycles, the B80 maintains exceptional performance and safety throughout years of regular use. Its LiFePO4 chemistry offers superior thermal stability, ensuring consistent output and long lifespan compared to traditional lithium-ion batteries.

The B80 connects seamlessly to compatible units such as the Bluetti AC60 and AC180, expanding total system capacity for longer runtime and higher energy availability. Using Bluetti’s intelligent plug-and-play expansion interface, the battery automatically balances charge and discharge rates with the connected power station, optimizing efficiency without user input.

Flexibility is a key part of the B80 design. It can function as an independent DC power bank or as a direct expansion module. When used on its own, it supports USB-C, USB-A, and 12V DC outputs, making it perfect for powering small electronics like laptops, cameras, and LED lights.

Recharging options are versatile and fast. The B80 can be charged via solar input, AC adapter, car charger, or through a connected Bluetti power station. Combined with the AC60 or AC180, it forms a scalable system that adapts to short trips or extended off-grid stays.

Durability is at the core of its construction. The IP65-rated enclosure protects against dust, splashes, and rain, making it well-suited for outdoor environments. Reinforced corners, a solid carry handle, and a compact 9.9 kg design make it easy to transport and store.

An advanced Battery Management System (BMS) ensures real-time protection against overcurrent, overheating, and voltage fluctuations. The system constantly monitors performance to guarantee stability and extend battery life, even during demanding use.

Sustainable, silent, and maintenance-free, the Bluetti B80 Expansion Battery embodies the freedom of portable power. Whether you’re charging devices in the wild, extending your van setup, or preparing a reliable backup solution, it provides dependable energy wherever the road takes you.
