  • 36V Cordless NANO Lithium-Ion 7-1/4 in. Circular Saw Kit


    How many more cuts will I get from this saw compared to an 18 or 20 volt unit, with the same amp hour battery? Can I get a 36 volt battery larger than 4.0 ah? As you know, the 18 and 20 volt units are coming with 5 and 6.0 ah batteries now. What does this mean in comparison? ...... In other words, does an 18v 6.0 ah system give the same performance as the 36v 4.0 ah? Is this unit brushless? If not, how does that play into the comparison?

      Amps determine run time, not the voltage. a 18V battery with 4 amp hr will have the same run time as a 36v battery with 4 amp hours. An 18v 6.0 amp hr battery will have a longer run time than a 36v 4 amp hour battery
