4x 18650 multiple battery charger with space for 4056 circuit

<p>Why charge one 18650 when you can charge up to 4 at a time!</p> <p>It just takes 4x as long of course.</p> <p>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)</p> <p>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!</p> <p>Note: I've not made a cover for the circuits. Couldn't be bothered :).</p> <p>Only use batteries which are of similar voltage at point of inserting. Preferably also from the same batch.</p> <p>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!</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.28mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> Eryone PLA Silk Blue</p> </p></p></p> Category: Electronics
