Bluetti B300 Expansion Battery – 3072Wh LiFePO4 Modular Power Storage – P-B300-UN-GY-BL-010

The Bluetti B300 Expansion Battery is a high-capacity, modular power storage solution designed to provide reliable and efficient energy storage. Featuring 3072Wh of LiFePO4 (Lithium Iron Phosphate) energy storage, this battery is ideal for use with Bluetti power stations, extending the power capabilities for both residential and off-grid applications. It is designed for easy integration with Bluetti's ecosystem, ensuring a seamless energy experience.

Product Features

High-Capacity Storage

With 3072Wh of energy storage, the Bluetti B300 Expansion Battery offers ample capacity to power devices and appliances for extended periods, ensuring uninterrupted power supply for home or outdoor use. The large capacity is perfect for off-grid energy systems, backup power, and outdoor adventures.

LiFePO4 Technology

Built with LiFePO4 (Lithium Iron Phosphate) technology, the Bluetti B300 provides superior battery safety, longevity, and thermal stability. LiFePO4 batteries are known for their high efficiency, long cycle life, and environmentally friendly features, making them an excellent choice for reliable energy storage.

Modular and Expandable

The Bluetti B300 is a modular battery that can be stacked or combined with other Bluetti batteries for additional capacity. This flexibility allows users to customize their energy storage based on individual needs and requirements, whether it's for a small off-grid cabin or a larger energy system.

Compact and Portable

The compact and portable design of the Bluetti B300 makes it easy to transport and install in various locations, from RVs and homes to outdoor setups. Despite its high capacity, the battery is lightweight and manageable, offering users an easy-to-handle solution for power storage.

How It Works

The Bluetti B300 Expansion Battery stores energy from a primary power source, such as a Bluetti solar generator, and provides this stored energy as needed. The battery can be charged via AC, solar, or car, and the stored power can be used to run devices, charge electronics, or power home appliances.

Energy Storage and Conversion

The B300 stores energy generated from solar panels or the grid and converts that energy into usable power through its output ports. This allows users to access electricity even in remote locations without relying on the electrical grid.

Expandable Power Capacity

By stacking or connecting multiple B300 units, users can scale their energy storage capacity to meet higher power demands. This modular system makes the Bluetti B300 ideal for a variety of applications, from small backup systems to large off-grid solar setups.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
