    Reliable Energy Expansion for Every Situation

    1800W Output

    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.

    Expandable Battery

    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.

    Quiet Operation AC Charging

    ⚡ 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 Charging

    ☀️ 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.

    Car Charging

    🚗 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

    🔌 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.
