Description
The EB300 Extra Battery (EF-RV-E01-1) is the essential accessory for users who need more runtime from their EcoFlow RIVER 3 system. By simply stacking the RIVER 3 on top of the EB300, you effectively double your power availability. This means you can keep essential devices like Wi-Fi routers, LED lights, and smartphones running for twice as long—providing up to 60 hours of power for a 3W router, which is critical during extended grid failures.
Durability is a core feature of the EB300. Its internal battery chemistry is automotive-grade LiFePO4, known for its thermal stability and long-term performance. The unit is also built to survive real-world conditions, featuring a fire-retardant shell and an IP54 rating that protects against splashes and dust. This makes it an ideal companion for outdoor photography, remote site work, or backup in dusty environments.
Safety is managed through the main unit’s X-Guard Battery Management System (BMS), which monitors the EB300 in real-time. It protects the expansion battery from over-voltage, overloading, and extreme temperatures. Because it requires no external cables, there is no risk of loose connections or power loss through cable resistance. It is the smartest, most efficient way to scale your portable energy needs without the bulk of a larger standalone generator.
