1) Makita
Makita BSS610 LXT

9 Overall Makita Recommendations
3 Makita LXT recommendations
Ranked “Best Cordless”: ConsumerSearch
Makita’s 18-volt LXT Lithium-ion Circular Saw
Makita – LXT400 Cordless Combo Kit
“The 6-1/2-in. circular saw was sturdy and powerful, with excellent controls and adjustments. A dust blower kept the cutting line clear, and an LED light aimed at the leading edge of the blade was a genuine help when I was working in any conditions less than bright sunlight. I didn’t like the saw’s horizontal grip, but the light weight of the battery pack compensated by making the tool easy to handle.”

5 Milwaukee V28 Recommendations

Mike Guertin in Fine Home Building:
“On my last few remodeling projects, I set aside my corded circular saw and relied solely on the new cordless Milwaukee V28. Even though I was crosscutting 2x lumber, ripping full sheets of 3/4-in. plywood, and trimming MDF (medium-density fiberboard) panels, I had to keep reminding myself that I was using a battery-powered saw.”

Lithium-Ion Hands On -Though I value the effort that went into the Tools of the Trade overview of Lithium Ion cordless tools, they don’t explain the hierarchy of the tools, or indicate if there’s any preference of one tool over the other. Also, they only talk about the positives. Good overview, but not super useful for decision making in my opinion.
