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. *AFH1500 Frame & Harness and ADB1000 adapter included
