Default LiPoly in Cordless Drill

I know this is a little off subject but with the availability of decent LiPoly batteries at resonable prices and high current to weight ratios, has anybody replaced the Nicads in their Cordless drills? I would think that one would get better weight to performace since a cordless drill is just an electric motor.

thanks

Default RE: LiPoly in Cordless Drill

Every power tool manufacturer has plans to introduce Li Ion cells in their tools in 2006. The cells chosen are a new type that has about half the energy density of our lightest Li Pos and produces some 2.5V instead of 3.7. Extreme lightweight is not a requirement for power tools as it is for airplanes. They are cylindrical, wound cells. The important word about these cells is that they are still Lithium cells, thus still have much the same explosive potential of the usual Li Ion. The word of warning is that the thing that makes them safe for power tools is the same thing that makes Li Ion safe. Thatis, they must be charged using the charger that comes from the tool manufacturer with the pack and they must be used in the tool with the discharge control circuit in the tool. If you start disassembling tool packs and using them as we do for RC, potential disaster awaits.

A safe, tough, protected Li-Ion cell has been introduced around a year ago by Kontronik, the Konion http://www.kontronik.com/Konion1100.htm
Protected against heat, overcharging, short cut... .

In fact, there are a couple of Li-Ion powered drills in our stors.
