The new EGO Power+ commercial backpack battery delivers the power output and run times needed for demanding jobs. In fact, it has the same power as 80% of the petrol products currently in use. All minus the noise, fumes and vibration of course. To make sure it's extremely tough and durable, we tested it to the extreme too. The commercial backpack battery can handle the heaviest downpours and still power the tool. Plus, the super-robust casing is designed to take all the knocks you can throw at it.
