Description
The Expion360 EX2 Edge is a premium 12.8V 240Ah LiFePO4 deep cycle battery engineered for RV solar systems, off-grid setups, and demanding mobile power applications. At its core is the proprietary Vertical Heat Conduction (VHC) internal heating system, which warms battery cells evenly for reliable performance even in cold-weather conditions. Built-in Bluetooth connectivity pairs with the Expion SmartTalk app, giving you real-time monitoring and control of your battery bank from your phone.
The EX2 Edge also features Controller Area Network (CAN) Bus communication for seamless, high-speed integration with compatible RV power systems and charge controllers. An integrated Advanced Battery Management System (BMS) safeguards against short circuits, over-voltage, under-voltage, and overcurrent events - protecting your investment for the long haul. Backed by a 12-year manufacturer warranty and rated for over 3,500 charge cycles, this battery is built to deliver years of dependable, high-efficiency power.

FAQ
What does the VHC Internal Heating System do?
The proprietary Vertical Heat Conduction (VHC) system heats the battery cells evenly from within, allowing the battery to charge and operate efficiently in cold temperatures. Without internal heating, LiFePO4 batteries should not be charged below freezing - the VHC system solves this by bringing cells up to safe operating temperature automatically, making it ideal for winter camping or cold-climate use.
What is CANBus communication and why does it matter?
Controller Area Network (CAN) Bus is a communication protocol that allows the battery to talk directly with compatible RV power systems, inverters, and solar charge controllers. This enables faster, more accurate charge management and system-level coordination compared to batteries that rely on simple analog signals. If your RV system supports CANBus, you'll get smarter, more efficient charging and real-time system data.
Can I connect multiple EX2 Edge batteries together?
Yes. The Expion360 EX2 Edge is designed to work with compatible Expion accessories and can be integrated into multi-battery bank configurations. The SmartTalk Bluetooth app allows you to monitor and manage multiple Expion batteries from a single interface. Always ensure you are connecting batteries of the same voltage, capacity, age, and type when building a bank.
Is this battery safe to use in an enclosed RV battery compartment?
LiFePO4 chemistry is one of the safest lithium battery chemistries available - it is thermally stable and does not off-gas under normal operating conditions the way some other lithium chemistries can. The integrated BMS provides additional protection against common fault conditions. However, the manufacturer specifies this battery is for indoor installation only - do not install in an exposed outdoor location.
What is the return policy for this battery?
Due to shipping regulations regarding hazardous materials, lithium batteries cannot be returned or refunded after the sale. Please carefully verify compatibility with your system, vehicle, and charge setup before purchasing. If you have questions about fitment or compatibility, contact us at service@omahasportsandgames.com before placing your order.
How does this compare to a lead-acid battery?
The EX2 Edge offers dramatically better performance than lead-acid in nearly every measurable way. It delivers over 3,500 charge cycles versus 300-500 for most lead-acid batteries, charges faster, weighs significantly less for equivalent usable capacity, and maintains consistent voltage output throughout its discharge cycle. Over the life of the battery, the higher upfront cost typically results in lower total cost of ownership compared to repeatedly replacing lead-acid units.
