  • Lidl Battery packs 20V?

    From Charlie+@21:1/5 to All on Sat Oct 2 11:32:08 2021
    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+

    20V is marketing speak for 18V, so multiples of 5 cells per pack

    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.

    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.

    Speaking of confusion, this might be of interest:

    Thanks evryone for kind information - and helpful links!
    Just what I needed.. C+
