I settled on the 40V Ryobi tools for my gardening efforts. I’ve been using them for a number of years now and I use the Expandit series of tools with a couple of Ryobi motors.which come with the attachments. I have a three battery capacity 40V Ryobi charger and lots of expandit tools to go with it.
I have chainsaws, a blower, a hedge trimmer, weed eater and roto tiller attachments. I’ve not had a single one of them die. They all work great.the expandit series has the advantage of attaching to my gasoline powered expandit motors, too if I need more power, but the electric does a great job most of the time.
Lastly, my impact drivers, drills jigsaw and circular saw are Dewalt 20V max tools. I also have an old 18V drill, impact driver and sawsall with an adapter for the 20V lithium batteries.
Lastly, I inherited a bunch of Ryobi 12V tools where the batteries have died. The are packed away until I decide to by new batteries.
Overall I’ve only had one Dewalt drill die and all of the original 18v NiCd batteries are dead. (I repaired the drill as well) My adapter makes these still viable tools though. (Dewalt sells new Lithium batteriies for them but for now I;m happy with the adapter.
