The technology used in the EGO POWER+ system breaks the mold. It begins with the industry’s first 56-Volt Lithium-Ion powered battery. Unlike other battery packs, which are shaped like bricks and retain heat, ours follows a patented “arc” design. Inside, we developed the most advanced software management system ever created in a home lawn and garden product. And our proprietary “Keep Cool” cell technology works with each battery cell to maintain long-term power and unmatched performance. The EGO POWER+ system also boasts a revolutionary charging system. In just 30 minutes, a depleted battery can be fully recharged. Another first in the lawn and garden world. Power beyond belief starts with better technology. That’s what puts EGO’s power, performance and durability on whole new level.
