Serial connection of batteries

Hello team supermagnete!

I like to play around with electronics and can make use of your magnets for a very practical purpose. Often I require a specific voltage but I don't have professional tools or the classic serial connection box. Then I thought of your magnets, because I can easily use them to build my own serial connector using individual batteries.

To connect standard AA-batteries I used small disc magnets S-08-03-N which you gave me as a free sample with one of my orders.

You need only one magnet between each of the batteries...

... and at the end of the row of batteries you trap a bit of wire between two magnets.

Given the strong attractive force between the super magnets, it is advisable to place the magnets with alternating poles (N/S/N/S) because even with a battery between them, they can reject each other.

Look at that: it works wonderfully :-)
