Parrot Disco 18650 3S2P Battery Dock

thingiverse

3D printed a custom dock for my Parrot Disco's 18650 battery. The result is a 3S2P lithium-ion pack that puts out 10.8 volts and 6500 milliampere-hours of power, weighing in at just 335 grams with the batteries, dock, and wires included. The idea behind this project was inspired by a blog post on seidel-philipp.de. If you're interested in learning more about how to build your own long-range lithium-ion battery, I highly recommend checking out their article on the subject. **Warning: Proceed with Caution!** If you're not familiar with electronics or soldering, please do not attempt to recreate this project. The consequences of a mistake can be severe, and I will not be held liable if something goes wrong. When working with the positive pole, exercise extreme caution. The negative pole is located just below it, and if you accidentally create a short circuit while using liquid soldering tin, the cell may become extremely hot and even explode under certain circumstances. To avoid this risk, use a minimal amount of solder and take care to heat only the contact surfaces briefly with a large soldering tip at around 450 degrees Celsius. The goal is to melt just enough tin to create a strong connection without overdoing it.
