EcoFlow DELTA 3 Smart Extra Battery – 1024Wh Expansion Module
Expand your EcoFlow power system with the DELTA 3 Smart Extra Battery – a modular 1024Wh lithium battery designed to double your storage capacity. With long-life LFP chemistry, plug-and-play simplicity, and smart monitoring, it's the perfect upgrade for extended off-grid adventures, home backup, and 4WD touring.
Expandable Energy for Longer Runtime
The EcoFlow DELTA 3 Smart Extra Battery connects directly to your DELTA 3 or DELTA 3 Plus, instantly adding 1024Wh of capacity. It's stackable, space-saving, and purpose-built for powering your lifestyle on the road or off the grid.
Long-Lasting LFP Battery Chemistry
Engineered with Lithium Iron Phosphate (LFP) cells, the battery offers over 4000 charge cycles—giving you up to 10 years of daily use while maintaining 80% capacity. It’s built to perform in the most demanding power setups.
Smart Monitoring with EcoFlow App
Keep tabs on power usage and battery status in real-time via the EcoFlow app or the integrated screen. Whether you’re off-grid or managing backup power at home, smart controls put you in charge anywhere, anytime.
Reliable Energy Expansion for Every Situation
Effortless Plug-and-Play Expansion
Forget complex setups. Just plug into the Extra Battery port on your DELTA 3 or Plus, and the EFDELTA3-BAT syncs instantly to expand your total capacity to 2048Wh—ready to power longer adventures and critical appliances.
Stackable & Compact for Easy Storage
At just 9.6 kg and 1/3 the size of the DELTA 2, this extra battery saves space and weight. Stack it vertically with your main unit to keep your setup clean and organised, whether indoors or mounted in a 4WD or RV.
⚡ Recharge via Main Station
The extra battery charges automatically via the main power station using AC input. No additional cables or adapters required—just connect and go. Fully recharges when the primary unit is recharged.
☀️ Solar-Ready Setup
Use your EcoFlow solar panel array connected to the DELTA 3 system to recharge both batteries in sync. This extra capacity makes remote solar setups more powerful, giving you extended use for fridges, lighting, and comms gear.
🚗 Top Up On The Move
While driving, your main unit charges via the alternator or 12V socket—recharging the extra battery simultaneously. Stay powered across long distances without stopping for mains power.
🔌 Generator Charging Compatibility
Whether you’re powering your system with the EcoFlow Smart Generator or a third-party generator, the Smart Extra Battery works alongside the DELTA 3 to increase backup power and runtime in extended outages.
