Lipo mountable smoke stopper and switch

thingiverse

This is my version of a simple smoke stopper. It features a 12V 21W light bulb in series with the switch to limit current output while providing a visual warning that high current is being pulled. The switch eliminates the need to connect and disconnect the XT60 from the load every time you want to power cycle, reducing wear on the XT60 connectors. I used a SPST rocker switch, an XT60E-M connector, a 12V 21W light bulb, an XT60 plug with leads, and 16AWG wire. The holes for the wires accommodate up to 12AWG. I chose a lead from a dead battery with 12AWG for added robustness and thick insulation of the wires. For internal connections, I used 16AWG wire, but you can opt for smaller gauge depending on the bulb you use and the battery you connect. CAUTION: If soldered incorrectly or insulated insufficiently, you might short your battery, potentially causing a fire. Double-check your work, test with a current-limiting power supply (or another smoke stopper), and never leave it unattended while connected to a battery. I will not be held accountable for any damage caused to property, yourself, or others. Use caution and exercise discretion when working with this device.
