14V Impact Driver with 18V Carvex Battery

[griph0n]

I wonder waht would happen if I put the 18 V in the 15V tool.........  Not gonna do it, but I had it slipped in my hand before I noticed.

The batteries are designed to not fit a tool that they should not be used on. Other direction works though .......  15v battery on 18v tool.
