I have 18v Brushless Makita for all Cordless hand tools. Have had them for years and never had a battery go bad. Just got a 4.5" right angle grinder, die grinder, and plunge router....I can see now I'll have to get another right angle grinder....That thing is nice! The combo hammer drill/driver is nice. No more dragging the hammer drill out to put tapcons in concrete. The 1/2" high torque Impact is unbelievable! It delivers 740 ft lbs of tightening torque and 1,180 ft lbs of nut busting torque....It will twist a wheel stud right off if you aren't careful...
For blowers, weedeater, and push mower....I'm an 80v Kobalt fan....The weed eater and Push mower are awesome! The blower is great for cleaning out the garage. Not enough umfff for the cw...Although I think it would be hard to beat the Stihl 600 backpack blower with a battery power blower, just not there yet...They didn't have the 700 when I got mine...Might have to trade the 600 in and get the 700 battery start.....Would be nice to not have to pull start anything ever again! Did I mention it sure is nice not to have to drag around extension cords any more?!?!?
