Jefftron Mosfet - V2, rear wiring connects an extremely small mosfet directly to the Version 2 mechanical switch contacts, allowing the mosfet to be installed entirely inside the gearbox with ease. The circuit prevents sparking that occurs in traditional mechanical trigger systems, which eventually leads to carbonized switch contacts. The circuit reduces the electrical resistance compared to a mechanical switch. This allows the motor to draw power from the battery more efficiently. Lower resistance makes the electrical system more effective, resulting in a higher rate of fire and reduced trigger delay.
The package includes suitable motor and fuse connectors as well as heat shrink tubing. In addition, the package contains a highly conductive T-connector (Deans) for battery connection. The connectors are separate and require soldering the wires to the connectors during installation. In the wired version, the wires connected to the circuit itself are pre-soldered to make assembly easier.
Specifications:
- Mosfet integrated with SHS-manufactured V2 switch contacts
- Easy to install in all V2 gearboxes
- Use a maximum of 1.5qmm (AWG16) power wires and 25qmm (AWG21) signal wire
- Designed for continuous use with a maximum current of 25A. For heavy builds, we recommend the Mosfet II circuit.
