Experience the pinnacle of energy storage with Expion360’s premium 48V lithium battery collection. Whether you are upgrading a golf cart for extended range, building a robust off-grid solar array, or outfitting a high-draw RV power bank, our 48 volt LiFePO4 lithium batteries deliver unmatched performance, safety, and longevity.
Stepping up to a 48V system means drawing fewer amps to produce the same amount of power as a 12V setup. This allows for thinner wiring, reduced heat generation, and maximum electrical efficiency. Built with premium structural components and advanced Smart Battery Management Systems (BMS), our batteries are engineered to withstand the harshest off-grid environments while protecting against overcharging and extreme temperatures.
We stand behind our engineering with one of the most comprehensive warranties on the market. When you buy Expion360, you are securing reliable power for the next decade of adventures.
No bots and no overseas call centers. Our dedicated team in Redmond, Oregon, is ready to help you size your battery bank, troubleshoot setups, and get you back on the road fast.
Safety isn't optional. Our batteries are rigorously tested to meet UL 1973 standards for stationary energy storage, ensuring maximum protection against overheating, vibration, and electrical faults.
Don't let winter stop you. Our exclusive Vertical Heat Conduction (VHC™) system evenly warms the battery core, allowing you to safely charge your system even when temperatures drop well below freezing.
Engineering reliability where it matters most.
Our proprietary "Smart" BMS protects your investment. It features low-temp discharge and auto-shutoff for cold weather performance, alongside high/low voltage shutoffs, short-circuit protection, and overcurrent disconnects. The BMS is structurally bolted to the pack with an oversized heatsink for years of trouble-free operation.
We are the first in the industry to integrate rubber feet directly into the case, eliminating vibration and sliding. The case is crafted from fiberglass-infused ABS plastic (meeting UL 94V-0 fire retardant ratings) with radiused corners for structural strength.
We eliminated fragile solder points. Our cells are welded via thick copper machined collector plates, creating a mechanical backbone that reduces resistance and heat buildup. Our terminal pads are 96.7% larger than standard terminals, featuring opposing connection points for flexible mounting and reduced cross-polarity risks.
Buying lithium is an investment in your freedom. We back that investment with a 12-year warranty—one of the best in the business. Combined with our U.S.-based customer support team trained specifically in lithium technology, you can explore with total confidence.
No, you should not mix chemistries. Lithium batteries have different voltage curves and charging requirements. For the best performance, replace your entire bank with Expion360 LiFePO4.
While our batteries can work with many standard chargers, we recommend a charger with a specific Lithium (LiFePO4) profile to ensure you get a 100% full charge and balance the cells properly.
Lithium batteries cannot accept a charge below freezing (32°F) without damage. Our VHC™ technology uses internal heating pads to warm the battery cells automatically, allowing you to charge safely even in winter conditions.
Expion360 batteries are rated for 5,000+ cycles at 80% depth of discharge. For the average user, this translates to 10–15 years of service life.
UL 1973 is one of the most rigorous safety standards for energy storage systems. Achieving this compliance means our battery packs have passed extensive testing for resistance to abuse—including overcharging, short-circuiting, and fire exposure. For you, this means verified safety for your family and your rig, often meeting stricter requirements for insurance and marine regulations that non-compliant batteries cannot pass.
While UL 1973 covers the entire battery pack, UL 1642 focuses specifically on the individual lithium cells inside. Using UL 1642 recognized cells ensures that the foundational building blocks of our batteries have been independently tested for stability and safety. We don't cut corners; we build our packs using only top-tier, certified cells to ensure maximum longevity and reliability.
Our 48-volt LiFePO4 batteries are specifically engineered for high-draw applications that demand maximum efficiency. They are the ultimate power upgrade for golf carts, light electric vehicles (EVs), large off-grid solar arrays, marine propulsion systems, and heavy-duty RV house battery systems. Stepping up to 48V drastically reduces amp draw, meaning your system runs cooler and more efficiently.
Yes. To safely maximize the lifespan of your battery, you must use a lithium-specific 48V charger or a solar charge controller programmed for the LiFePO4 charging profile. Standard lead-acid chargers do not supply the correct voltage parameters and can damage the internal cells.
Upgrading from traditional lead-acid or AGM to Expion360 lithium cuts your battery bank weight by roughly 50%. For example, instead of wiring multiple heavy 6V or 8V lead-acid batteries together to achieve 48 volts for a golf cart, a single Expion360 48V GC2 battery provides the required voltage in one drop-in unit, shedding hundreds of pounds and improving your vehicle's speed and handling.
