FAQs

Installation & Fitment

Yes. This battery will fit in your battery box. It is a direct "drop-in" replacement for standard lead-acid or AGM Group 27 batteries, meaning you likely won’t need to modify your battery tray or tie-downs

Yes. Unlike lead-acid batteries that can spill, our LiFePO4 batteries contain no liquid acid and can be installed in any orientation (upright, on the side, or on the end) to fit tight spaces in your RV or boat.

Charging & Compatibility

For the best performance and fastest charging, we recommend a charger with a specific LiFePO4 profile (14.4V – 14.6V). However, this battery is compatible with most standard AGM/Lead-Acid chargers, though they may not charge the battery to 100% capacity.

Yes. You can connect up to four (4) Expion360 batteries in series to create a 24V, 36V, or 48V system, or up to four (4) in parallel to increase your total amperage capacity. Always ensure all batteries are at the same voltage before connecting.

Features & Technology

The Vertical Heat Conduction (VHC) system allows you to charge the battery in freezing temperatures (down to -4°F). The heating element automatically activates when it detects a charge current and the temperature is below freezing. It uses the energy from the charger—not the battery itself—to warm the internal cells before allowing a charge to flow.

No, it is not required. This battery has a built-in SmartTalk™ Bluetooth BMS. You can download the free Expion360 app to view real-time data like State of Charge (%), Voltage, Current, and Temperature directly on your smartphone.

The battery is housed in a rugged case with an IP66 rating. This means it is fully dust-tight and protected against heavy seas or powerful jets of water, making it ideal for marine and overland applications where moisture is a concern.
