Ryobi tools are grabage. Avoid.
I recommend the Ryobi ONE Kenobi. Use the force (of the drill). I'll see myself out...
Li-ion. Can recommend the 2Ah ones, I have a few from previous kits that charge fast and last a long time. eBay knockoffs available too at a cheaper rate but not tried any as of yet.
Are those Nicad batteries?
No they aren't. They are both part of the Kingfisher Group.
