Designed for use with Husqvarna battery products, the FLEXI system of the battery belt is ideal for comfortable and productive work away from an electrical outlet. Placing the weight in the middle of the user, and not in the arms, reduces the user's fatigue so that he can work longer and more efficiently. It allows you to easily carry batteries, oil, water and other accessories wherever you go. It is made of high quality materials and is designed for flexibility, comfort and convenience. For users with a new Husqvarna battery product (software update for products required before 2017).
