18650 dummy battery

thingiverse

You can utilize this model as a dummy battery for recharging lithium-ion cells within an 18650 cell charger. For the battery terminal, I opted to use wood screws initially, but then added a wire by soldering it on. Unfortunately, the plastic melted during the process. A more effective approach would be to employ a bolt with a nut, eliminating the need for soldering altogether. Length: 60 mm Diameter: 18mm
