EcoFlow Fixing Metal Tab for Secure Battery Stacking

The EcoFlow Fixing Metal Tab is a purpose-designed mounting accessory that ensures safe and stable stacking of multiple EcoFlow battery packs. This metal tab is required when three or more battery packs are stacked together, helping prevent movement and maintain correct alignment in high-capacity power setups.

In advanced configurations—such as connecting two EcoFlow DELTA Pro Ultra sets or linking three batteries to one inverter—the Fixing Metal Tab plays a critical structural role. It is installed on the battery positioned directly beneath the first inverter, where stability is most important. By locking stacked batteries firmly in place, the tab reduces vibration, shifting, and stress on electrical connections, which can occur in mobile, off-grid, or high-load environments.

It integrates cleanly with EcoFlow’s modular design philosophy, making it a small but essential component for users expanding their energy storage systems safely and correctly. For anyone building larger EcoFlow battery stacks, this fixing tab ensures long-term reliability and peace of mind.
