You can buy the adaptor and use the 20v batteries on them.
Anyone still invested in the Dewalt 18v system?
I've got a bunch of Dewalt 18v tools. Most of them work as expected, a couple are in need of repair, namely the jigsaw and 1/2" impact. I've got three lipo batteries for them, but all of the NiCad batteries wore out.
Looking to unload all of the 18v tools, as I'm moving to 20v stuff. LMK if anyone is interested, I can take some pics for you.
