Cordless 5" angle grinders

[Sberry]

How many amps are these cheap grinders, I do a lot of power brushing. My choice for grinders has always been Hitachi but if these can cut the mustard it's money in my pocket.

The B&D will tire a guy out in a hurry, runs a brush well.

The OP was talking about 5" grinders here so may as well ask,,,, Where are you guys getting 5" wheels?

or are most people using 4 1/2" wheels on the 5" grinders?

I know they make the 5" but not too many in the local big box stores.
