4x 18650 multiple battery charger with space for 4056 circuit

Why charge one 18650 when you can charge up to 4 at a time!

It just takes 4x as long of course.

This also has a slight extension on the space available for the 4056 circuit, as the original design didn't fit the ones I have (which have a little extra plastic near the OUT- and OUT+ points)

The whole thing is quite chunky. If I had to do it again, I'd probably use a thinner design, but hey ho, this thing works fine for me!

Note: I've not made a cover for the circuits. Couldn't be bothered :).

Only use batteries which are of similar voltage at point of inserting. Preferably also from the same batch.

Finally, only use this design if you fully understand the risks associated! I bear no responsibility for any negative impacts you may experience from using this design!
