Battery Capacity Tester

thingiverse

The battery capacity tester by Geekcreit places a battery under load and measures it's performance on an LCD display. The tester includes a battery socket for testing 18650 batteries, though it can test other battery dimenstions with a voltage up to 5V via a micro USB connector. The battery capacity tester is a self-contained, but open printed circuit board with integrated LCD display. Here is my 3D model of the tester. Maybe in future I will design a 3D enclosure to add further physical protection for the tester. If you're like me, it doesn't matter how much care you take, it's still possible to miss details in the 3D design. Typical missed details that will lead you into problems include: - Parts encroaching on others. - Hole spacings misaligned. A 3D model of each component incorporated into your design helps avoid some of the design pitfalls. I've included the STEP CAD file to assist people to incorporate the model into their designs. My print is made in PETG 1.75mm Aurarum neutral filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer. I hope you can find this design useful, too. Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
