The tool driver Li-ion 2Ah and 4Ah packs are in Lidl UK at the moment.
Anyone happen to know how many cells (in series) these really are? They
have quoted an ambiguous 20V voltage, could be either 5 or 6 series
cells.. anyone know or can measure the charged volts - Thanks C+

You can also just measure the voltage across the battery pack
terminal. LiIon is nominally 3.7v per cell. For 5 cells, you should
see 18.5 volts. If you just charged the battery to it maximum save
voltage of 4.1V, you'll see 20.5V. The "20V" rating is from
marketing, which believes that bigger numbers sell better but decimal
points create confusion.

This tool perhaps?

In general you get better answers if provide specifics such as maker,
model, etc.
Here's a video of the battery pack teardown:

I count five INR18650E cells: ><https://lygte-info.dk/review/batteries2012/Parkside%20INR18650E%202000mAh%20(Blue)%20UK.html>
Looks like a tolerable cell, but nothing spectacular. You might want
to measure the operating current of the tool while drilling to make
sure the current stays mostly under 20A maximum.
