The STIHL MSA 160 C-B Battery Chainsaw is a game changer in chainsaws. Lightweight, powerful and east to start. Being a battery its  very quiet. With no mixing. No cords. And almost no sound. (Your neighbours will love this saw as much as you do.) The STIHL MSA 160 C-B is powered by a Lithium-Ion battery. This little workhorse starts instantly, delivering 36 volts of power from its commercial-grade, high-torque brushless motor. Enough power to take on just about any cutting job in your yard. And the Quick Chain Adjuster allows you to adjust the chain tension without tools for added convenience.
