Abstract: This application relates to a power tool system including a plurality of power tools, a plurality of battery packs and at least one battery pack charger and method for operating the power tools with the battery packs. This application also relates to a method for charging the battery packs and a method for monitoring a state of charge of the battery pack. In one implementation, the system includes an existing battery pack designed to provide (output) a relatively low voltage, an existing power tool designed to operate at the relatively low voltage, a new battery pack designed to provide (output) the relatively low voltage and a relatively high voltage, and a new power tool designed to operate at the relatively high voltage.

Abstract: The present invention is directed to a debris collection bag for a blowervac device that is carried on a user's back. This improves the user's mobility and allows an increased capacity for the collection bag. The bag's location provides a comfortable weight distribution by separating the weight of the blowervac from the weight of the collection bag. The bag has a dust dispersion system to direct dust away from the user. The bag has a closure located on the side which makes emptying the bag easier. The bag closure is provided to make opening and closing the bag easier and faster, and resistant to dust and debris.
