Get a 60 V battery, you won't regret it. has the same power as my 5" Bosch chain grinder! It also works well with 20 volt batteries but 2/3 the power and the batteries I have are small 2Ah only last 10 minutes. The protection is great, tool-less adjustment so you can turn it easily.The paddle shifter is comfortable, not too heavy even with the large battery, the grip is comfortable in my big paws.
