Why RV Enthusiasts Choose Expion360

The Ultimate LiFePO4 Battery Bank for Off-Grid RVing

Run High-Draw Appliances Off-Grid – Effortlessly power residential refrigerators, RV air conditioners, induction cooktops, and microwaves with our high-discharge LiFePO4 cells.
Expandable & Modular – Scale your system to match your energy needs.
12-Year Warranty – Deep-cycle reliability backed by industry-leading support.
Rapid 1C Charging Rates – Spend less time plugged into shore power or running a generator. Our lithium chemistry recharges up to 3x faster than traditional AGM or lead-acid batteries.
Unmatched Safety & UL1973 Certification – Our batteries meet the highest safety standards in the industry, featuring a "smart" BMS that protects against overcharging, short circuits, and extreme temperatures.

Unlimited Boondocking & Off-Grid RV Power

Experience true independence with Expion360. Our high-density LiFePO4 chemistry provides significantly more usable energy than traditional lead-acid or AGM batteries, which are typically limited to a 50% depth of discharge. With Expion360, you can safely utilize 100% of your rated capacity—giving you the freedom to dry camp for days longer without a generator or shore power

Lightweight LiFePO4: Maximize Your RV Payload

Expion360 lithium batteries are up to 50% lighter than traditional lead-acid batteries, reducing overall weight and improving fuel efficiency for smoother RV travel.

Fast Charging & Longer Battery Life

Weight is the enemy of fuel efficiency and safety. Expion360 lithium batteries are 50% lighter than traditional lead-acid batteries, allowing you to shed hundreds of pounds from your chassis. Our high-density cell technology also offers a smaller footprint, freeing up valuable storage space for gear. Whether you're building out a sprinter van conversion or optimizing a truck camper, our compact designs provide more amp-hours per square inch than the competition.

Winter-Ready: Heated LiFePO4 Batteries with VHC™ Technology

Don't let freezing temperatures cut your trip short. While standard lithium batteries cannot safely charge in the cold, Expion360’s VHC™ (Vertical Heat Conduction) internal heating technology keeps your cells at the optimal temperature. Whether you're winter camping or traveling through high-altitude passes, our self-heating LiFePO4 batteries ensure consistent power delivery and safe charging down to -4°F. It’s the ultimate peace of mind for year-round adventurers.

Solar-Ready LiFePO4: Optimized for RV Solar Systems

Maximize your renewable energy harvest. Expion360 lithium batteries are engineered to pair perfectly with RV solar panels and MPPT charge controllers. Unlike lead-acid, our LiFePO4 chemistry accepts a high current charge, allowing you to store solar energy much more efficiently during peak sunlight hours. Build a sustainable off-grid solar bank that provides silent, eco-friendly power without the need for a noisy generator.

SmartTalk™: Bluetooth Lithium Battery Monitoring

Take the guesswork out of your power levels. Our SmartTalk™ Bluetooth-enabled batteries sync directly to your smartphone, providing a live RV battery fuel gauge in the palm of your hand. Monitor your State of Charge (SoC), voltage, current draw, and individual cell health in real-time. Whether you're relaxing inside or sitting by the campfire, you’ll have total visibility into your LiFePO4 system without ever needing to pick up a multimeter.

Key Features

Lithium Cells

We use only the highest-grade lithium iron phosphate encased in steel and meeting theUL1642 standard(UL file no. MH64383). This material and engineering make for unparalleled reliability, stability, and safety.

Case Design

We took the standard battery case up a notch with built-in rubber feet, radiused corners, 96.7% larger terminal connection pads, interior molded ribs for structural security, and the highest-grade ABS plastics with additives for fire retardancy. Our innovative case design changes the scope of the industry.

Cell Pack

To keep our batteries as powerful and efficient as possible, we’ve welded our cells via thick copper/tin machined collector plates, welded all interior pack points, added a press broke flange at each end to create a mechanical backbone for the BMS, used high-grade wiring and ring terminals throughout, and treated connections with industrial epoxy for long-lasting protection.

Battery Management System (BMS)

Our “smart” BMS design has abundant features to provide you with the safety and performance you desire, such as: low-temp discharge, auto-shutoff, short circuit protection, low and high-voltage shutoffs, and overcurrent disconnect. Our structurally sound BMS board features a bolted design, eliminating all unnecessary solder, resulting in one cohesive pack for years of trouble-free performance.

Certification

Expion360 lithium batteries are held to the highest safety standards. Because of this, we are one of a small handful of companies to achieve a UL 1973 compliance
