Replacing old NiCads with a lion power pack is a cool idea. It would definitely give new life to old portable electronics, esp test equipment. You can buy (I am using them now) adapters so you can use a Makita battery in a Ryobi tool. The idea of battery teams is ridiculous, team <color> is ... I can't even. With the adapter, I can pickup a Ryobi specialty here or there. They make them for other combinations but I haven't used them. I have a Ryobi battery from a refurb tool purchase the combo set was cheaper than the single tool w/o battery. Homedepot confuses the hell out of me.
