Jefftron Mosfet - V2 integrates an extremely small MOSFET directly onto the Version 2 mechanical switch contacts, allowing the MOSFET to be installed entirely inside the gearbox with ease. The circuit prevents arcing that occurs in traditional mechanical trigger systems, which eventually leads to carbonized switch contacts. It reduces the electrical resistance compared to a mechanical switch, allowing the motor to draw more power from the battery. Lower resistance makes the electrical system more efficient, resulting in higher rate of fire and reduced trigger response time.
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 up to 25A current. For heavy builds, we recommend the Mosfet II circuit.
- Compatible with all batteries up to 17 V (Ni-xx 8.4V – 14.4V, LiPo 7.4V – 14.8V, LiFe 9.9V – 13.2V)
