The 40v system that Home Depot work great for small properties. When I lived in town, we had a very small property to maintain. I could mow, edge, string trim in 15 to 20 minutes and another 20 minutes to trim the bushes and hedges. I also have a 9 foot battery powered 9 inch pole saw and a 10 inch battery powered chain saw that I used several times a years to limb up the trains and remove dead limbs. I only had two or 3 trees to deal with.
With my large acreage property I currently have, battery and electric won’t work. I still use my pole saw and saw to work on the trees every year. I end up using 3 large cap. batteries in a two hour period. I find this still to be lighter and cheaper than using gas powered saws.
