I have a nice set of Bosch 18v (blue core batteries) power tools (1/2" drill, skill saw, sawzall, light) that I bought as a combo set some years ago. After about 4-5 years I bought some replacement batteries, probably from China, those have lasted abut 3-4 years (now dying). Recently my wife also gave me a nice Bosch 1/4" impact gun Li Ion a year ago, love it. So I have a nice set of older Bosch tools that all work great. And I have two new Li Ion batteries and charger that came with my new impact gun. I saw they now have conversion pieces that will mate my new Li Ion batts with my older Bosch tools. About $45 if I remember right. I hate to buy a whole new set of tools to get Li Ion, nor do I want to buy more NiMH batteries, given their reviews.
My Q: has anybody used these conversion pieces to do what I'm thinking about doing (they look poorly made)?
If so, any problems or advice? Randy
