Onewheel Battery Pack (The Lifejacket)

This is a detailed tutorial on how to set up an MPT (Motor Protector Terminal) system for charging electric skateboards like the Onewheel. It's a complex process, but I'll break it down into smaller steps. Here are the main sections: 1. **Tools and Materials Needed** * XT60 connectors * Female XLR plug * Wire (red and black) * MPT controller * MPT Mount * Pozi Pan Bolts * Wire Covers * Multimeter * Key 2. **Assembly of the Charge Cable** * Cut a length of wire to the required length. * Strip both ends of the wire and fold back the insulation. * Solder one end of the positive lead to pins 2 and 3 on the female XLR plug. * Solder one end of the negative lead to pin 1 on the female XLR plug. * Reassemble the XLR connector and slide up any insulation or sleeving you want to use. 3. **Adding the XT60 Connector** * Solder the positive terminal on the XT60 to the other end of the positive lead on the wire. * Solder the negative terminal on the XT60 to the other end of the negative lead on the wire. * Adjust the insulation or sleeving so that the charge cable is safe from shorting and no exposed wiring is visible. 4. **Sanity Check** * Use a multimeter to test for shorts between the positive and negative terminals of the XT60. * Verify that the terminals on the MPT controller connect back to the correct place. * Connect the charge cable to the XT60 and verify that pins 2 and 3 go back to the positive battery terminal, and pin 1 goes back to negative. 5. **Finishing Off** * Place the MPT controller on top of the MPT Mount so that the wires are pressed into the trench. * Use Pozi Pan Bolts to secure the wire covers in place. 6. **MPT Programming And Final Test** * Program the MPT controller to the desired voltages and max current settings. * Verify that everything works as expected with no magic smoke. * Connect the charge cable and verify if the desired voltage is present on the XLR. * Open the Onewheel app and check the board is charging.
