A 48V lithium system changes EVERYTHING.
More efficiency. Faster charging. Less weight. Bigger inverter capability. Whether you’re upgrading a golf cart, RV, marine setup, or off-grid rig — 48V power is the move for serious performance. 

From the compact GC2 48V to the high-density EX2 Edge 48V, Expion360 is building systems designed to go farther, run longer, and power more.

Which setup would you run a 48V system in first?

The Expion360 EX2 Edge gives you massive lithium power in an ultra-slim battery design that fits where traditional batteries can’t. That means more usable storage, cleaner installs, and serious off-grid capability.
Pair it with solar, DC-to-DC charging, and a pure sine inverter to create the ultimate adventure-ready power system.
