FAQ
Can I use this battery to replace my existing lead-acid batteries?
Yes, the Expion360 368Ah LiFePO4 battery is designed as a drop-in upgrade from lead-acid deep cycle batteries in most 12V RV and off-grid applications. However, you should verify that your charging system (converter, solar charge controller, etc.) is compatible with lithium battery charge profiles - specifically a charge voltage of 14.6 Vdc. Some older RV converters may need to be updated or adjusted for optimal lithium charging.
Can I connect multiple batteries together to increase my capacity?
Yes - this battery can be wired in series to increase voltage or in parallel to increase amp hour capacity. Expion360 recommends not exceeding four batteries in a bank and advises against mixing batteries of different ages or sizes. Always follow the wiring diagrams provided in the user manual for proper and safe configuration.
What BMS protections does this battery have?
The integrated Battery Management System (BMS) provides six key protections: short circuit protection, overvoltage protection, undervoltage protection, overcurrent protection, thermal protection, and automatic cell balancing. These features work automatically in the background to protect your battery and extend its usable life.
Can this battery be used as a starter battery?
No - this battery is not rated or designed for use as a starter/cranking battery. It is a deep cycle battery intended for sustained power delivery in applications like RVs, off-grid energy storage, and marine house banks. Using it as a starter battery is not recommended by Expion360.
What is the warranty, and are returns accepted?
This battery is backed by a 12-year manufacturer warranty from Expion360 - one of the best in the industry. Please read the full user manual for complete warranty terms and conditions. Important: Due to shipping regulations for lithium batteries (classified as hazardous materials), returns and refunds cannot be accepted after purchase. Please confirm compatibility before ordering.
How long will this battery last on a single charge?
Runtime depends heavily on your power draw. At 368 Ah and 4,710 Wh of stored energy, this battery can run a wide range of loads for extended periods. For example, a 100W device would theoretically run for approximately 47 hours. In real-world RV use, factors like inverter efficiency, simultaneous loads, and temperature will affect actual runtime. The battery is rated for over 4,000 full charge/discharge cycles, giving it a very long usable lifespan.
