Explore Expion360's Best-Selling LiFePO4 Batteries and Accessories

Best sellers are that way for a reason. Besides typically having a seal of approval from customers (sometimes the literal kind), best-selling products indicate that something is tried and true. Plus, best-sellers usually have the data to back it up, whether by recommendations, reviews, or third-party testimonials. At Expion360, we’re proud of every product we design, engineer, and manufacture. But this week is all about the top LiFePO4 batteries and accessories that power our customers’ pursuits around the States and beyond.

The following top sellers are a small sampling of the full accessory collection but highlight how each component protects your power system investment.

When designing our batteries, it was critically important that we include a robust battery management system that could handle voltage shutoffs, short-circuit protection, overcurrent disconnect, and more. To access this information and keep systems as safe as possible, we knew customers would need a battery monitor that was intuitive, simple to program, and easy to install. 

What’s included: 

  • Battery monitor display screen 
  • Brass measuring shunt
  • Aluminum shunt bracket
  • 35-foot data cable 
  • 22-gauge positive power wire

A Long-Term Power Solution You Can Trust 

Your off-grid venturing shouldn't be limited by your power source (turning around to stock up on supplies is another story). The best-selling batteries and accessories listed above are only part of the full scope when you choose Expion360. 

You also get a company deeply invested in outdoor pursuits and inspired by rugged, beautiful places. You get a team that goes off-grid and offline whenever they can, meaning we cater to customers with the same pain points and goals. Mostly, it means that your battery was created with genuine passion and the goal of crafting something the industry hadn’t seen before. 

On the flip side, we know our customers are looking for longevity. That’s why we created a 12-year warranty and expert-led customer support team to provide actionable feedback and advice to those needing it most. Investing with E360 means much more than a groundbreaking power system; it’s becoming part of a dynamic community.
