18650 Battery Test Jig

thingiverse

I'm designing a straightforward 4-wire battery test fixture that securely holds a single 18650 cell. The clip integrates a 10-amp battery current probe with a soldering end. I printed the design using PLA at 211 degrees Celsius and a 0.2 mm layer height. If you plan to use this setup for high-current testing, such as 5 amps, I recommend printing it with ABS instead. The original concept is based on a design found on Thingiverse (https://www.thingiverse.com/thing:38216).
