When it comes to demanding jobs, the EGO Power+ Commercial Backpack Battery delivers. Its power outputs and run time have the same power as 80% of the petrol products currently in use. All minus the noise, fumes and vibration, of course. We tested this extremely tough and durable battery in all conditions, so it can handle the heaviest downpours and still power the tool. Plus, the super-robust casing is designed to take any knocks you can throw at it. Charger Not Included (CHX5500E) Click here for details on our 30 Day Money Back Guarantee.
