Do you utilize battery-powered tools?

Handheld battery-powered tools have come a long way from their first iterations, especially over the past few years. I've started making the switch away from gas-powered equipment throughout the last few seasons for my business and have found the switch to be positive for my workflow and bottom line. This is a trend I believe will continue as batteries become more powerful and long-lasting.

Are you utilizing any battery-powered equipment and, if so, do you have any favorites you'd like to share??
