Looking for a smart, scalable power solution? The Oupes B2 battery isn’t just an expansion pack—it’s a versatile standalone unit ready to fuel your off-grid adventures.
From RVs to job sites, it offers flexible DC outputs, solar charging, and seamless Mega 2/Mega 3 integration—redefining portable energy with power, portability, and purpose.
In today’s energy-conscious world, portable power isn’t just a luxury—it’s a necessity. The Oupes B2 Battery stands out as a multifunctional expansion battery designed for Mega 2 and Mega 3 power stations, yet powerful enough to function independently. Whether you’re camping, working on a remote job site, or planning for emergencies, this battery delivers both reliability and adaptability.
The beauty of the Oupes B2 lies in its standalone capability. While it seamlessly expands the capacity of Mega 2 and Mega 3 systems, it also acts as an independent DC power source.
With this kind of flexibility, you can separate your AC and DC loads or even use the B2 battery alone without a paired power station.
This isn’t just a battery—it’s a complete power solution tailored for outdoor adventurers and serious DIYers. The front panel hosts an array of user-friendly ports, while the side houses the expansion and solar input terminals.
What makes it even better? Each output is independently switchable, giving users granular control over power consumption.
Despite its capabilities, the Oupes B2 doesn’t compromise on portability. At just 41.8 lbs, it’s lighter than many standalone batteries in its class.
For DIY enthusiasts and solar tinkerers, these numbers open doors to a whole new level of energy independence.
The B2 battery includes intelligent features for user convenience. From power syncing with the main station to safety-first design, it’s built with practicality in mind.
One design flaw worth noting: the dual-port flap doesn’t close when a cable is plugged in, exposing the unused port. A split cover would better protect against moisture and pests.
The Oupes B2 Battery is more than just an add-on—it’s a powerhouse. Whether you’re off-grid for days or looking to bolster your emergency power setup, this battery adapts to your lifestyle.
If you’re serious about solar DIY projects or need a trustworthy battery that evolves with your needs, the B2 is an investment worth every watt.
