Makita 18v battery meter
prusaprinters
A simple volt meter to measure the voltage of Makita 18v rechargeable batteries.Since they don't have one built in.Uses a cheap 3 wire LED volt meter (Amazon QR code link) or similar.Yellow crimp connectors (from home center, auto parts store etc…)4 M3 Hex head screws.I printed at 0.2mm height, 3 shells and 20% infill. Only the part that has overhangs that slides onto the battery needs supports.I used epoxy on the crimp connectors, and some hot glue to hold the meter in place.Connect the white and red to positive, and black to negative.
