Remember it's not all about raw voltage, the ampage of the battery is also important as this combined with the voltage will determine how much power the tool can deliver (volts x amps =watts).and for how long. You need to look at the torque spec for each individual drill as they all have different motors.

This the problem with a lot of the cheap big voltage cordless tools the sheds sell, they usually only have small ampage batteries.

My advice would be always buy the biggest amph batteries you can afford. If you are only going to use the tool occasionally then there are some real bargains out there, especially if you think about some of the older technology such as nicad or NimH batteries and lower voltage but higher amph batteries.
