With the DELTA Pro 3 Smart Extra Battery, you’re not just adding capacity—you’re enabling a smarter, more reliable power workflow. The modular design lets you scale your energy supply as demand grows, whether you’re powering a home office, a workshop, a tiny home, or a remote work site. The battery communicates with the DELTA Pro system in real time, balancing charge and discharge to maximize efficiency and minimize wear. In the event of a grid outage, you’ll be able to sustain critical appliances longer, and when electricity returns, the system can recharge faster to be ready for the next cycle. The result is a resilient power solution you can trust for everyday life and high-stakes environments alike.
Setup is straightforward for both DIY enthusiasts and professional installers. The Smart Extra Battery slots into the EcoFlow DELTA Pro family without sacrificing your existing monitoring, control, or alert features. You’ll see at a glance how much runtime remains, how the load is distributed, and when the system is charging, allowing you to manage consumption proactively. This clarity is especially valuable for high-demand households, RV owners, off-grid dwellers, and small businesses that rely on continuous power to protect customers, products, and data.
