EcoFlow DELTA 3 Extra Battery

The mission didn't end. Neither should your power.

The true nomad knows that "enough" is a dangerous word. When the storm rolls in, the basecamp expands, or the off-grid stint turns from a weekend into a month, you need a reserve that doesn’t blink. The EcoFlow DELTA 3 Extra Battery is the ultimate force multiplier for your DELTA 3 series setup—turning a high-performance unit into a long-haul energy fortress.

INSTANT EXPANSION, ZERO FRICTION

We don’t do "complicated" out here. This is pure Plug-and-Play hardware. One cable connects this beast to your DELTA 3 or DELTA 3 Plus, instantly adding 1024Wh of high-grade LFP capacity. No tools, no wiring, no downtime. Just more juice for the gear that keeps you moving.

BUILT FOR THE LONG HAUL

Like every piece of gear in a nomad’s kit, this battery is built to endure. Powered by Automotive-Grade LFP (LiFePO4) cells, it’s rated for 4,000+ cycles before it even hits 80% capacity. That’s over a decade of daily deployments in the toughest conditions New Zealand can throw at you.

THE NOMAD’S ADVANTAGE:

• Double the Endurance: Pair it with your DELTA 3 to bridge the gap through long nights or multi-day outages.
• Smart Charging: It doesn't just sit there. It charges and discharges in total lockstep with your main unit, keeping your system balanced and efficient.
• Tough & Compact: Weighing in at just ~9.6kg, it’s lean enough to toss in the rig but heavy-duty enough to survive the vibration of a corrugated backroad.
• Intelligent Monitoring: Use the EcoFlow App to track every watt. Monitor the health, temperature, and charge level of your extra cell from the palm of your hand.

SPECIFIED FOR SURVIVAL:

• Capacity: 1024Wh (The perfect 1:1 match for your DELTA 3 Plus).
• Compatibility: Designed specifically for the DELTA 3 Series, but plays nice with the DELTA 2 for versatile fleet management.
• Rapid Recovery: Supports the same lightning-fast charging speeds as your primary unit when connected.
• Peace of Mind: Backed by a 5-year warranty—because gear you can’t trust isn't worth the space in your truck.

Stop watching the percentage drop. Bolt on the extra capacity, leave the grid further behind, and stay out there until the job is done or the sun rises.
