Here are some of the differences between the gen 1 KCS 180B and Gen 2 KCS 4080 kobalt 80 volt battery powered Chainsaws. Video didnt go quite as planned. Single take. had an issue with a battery that seemed defective but turned out to be just fine so that was a weird fluke. Also had an issue with my Gen 1 cutting off which I don't remember ever happening before. Murphys law? Forgot to mention in the video this is a freshly cut black walnut tree. My Gen 2 saw has some issue and I don't know if its defective or if this is just how they are. Would love to hear to some feedback from others with the Gen 2 saw. I find I like the Gen 1 saw much better. I have made hundreds of cuts through logs this size and bigger with my Gen 1 chainsaw and have been very happy with it. One other thing I want to mention is that the generator saw seeps bar oil like crazy and has since new. One last consideration. I was able to buy a greenworks hard case and the gen 1 kobalt saw fits great but the gen 2 saw does not. I don't think Kobalt makes a hard case for the gen2.
