FAQs

Product Overview & Physical Specs

The EX2 Edge is designed with a unique "ultra-slim" form factor, measuring just 4.2 inches thick. This allows it to fit in tight spaces where traditional batteries can't, such as behind vehicle seats, in false floors, or mounted flat against a wall.

Dimensions: 21.9" L x 17.5" W x 4.2" H

Weight: 67.0 lbs (30.4 kg).

This is a 12.8V nominal Lithium Iron Phosphate (LiFePO4) battery with a capacity of 240 Amp-hours (Ah). It provides approximately 3072 Watt-hours (Wh) of energy.

No. This battery has an IP40 rating, which protects against solid objects (like wires or tools) but does not protect against water ingress. It should be installed in a dry, protected location, unlike the IP65-rated GC2 models.

Performance & Electrical Specifications

Recommended Charge Voltage: 14.6V
Float Voltage: 13.6V
Charge Method: CC-CV (Constant Current/Constant Voltage).

Optimum/Continuous Discharge: 120A
Max Continuous Discharge: 200A
Pulse Discharge: Up to 250A (3 seconds) or 300A (1 second) for starting heavy loads.

No, this battery is designed for 12V systems only. Do not connect them in series for 24V or 48V. You can, however, connect up to 4 units in parallel to increase capacity (e.g., 960Ah total).

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.

Yes, the battery has built-in Bluetooth. The SmartTalk™ app (available for iOS and Android) allows you to wirelessly monitor the battery's health, state of charge, voltage, and temperature. It can also aggregate data from multiple batteries into a single system view.

The EX2 Edge uses touch-safe, quick-disconnect terminals. These are designed to be safer and allow for secure, high-power connections while minimizing the risk of accidental shorts during installation.

Yes, it features CAN Bus communication ports for integration with compatible RV and marine power systems, allowing the battery to "talk" directly to inverters and chargers for optimized performance.

Installation & Warranty

The EX2 Edge features an Integrated Mounting System. The casing itself is designed with mounting points that allow you to secure it directly to floors or walls without needing expensive aftermarket brackets. You can also link multiple units together using this system.

Expion360 backs this battery with a 12-year warranty, ensuring long-term reliability for your off-grid or RV setup.
