Jefftron MOSFET V2, Stock Wiring

JeffTron MOSFET V2 is a professional upgrade designed to take the load off the traditional trigger contacts in your V2 gearbox (e.g. M4, M16, MP5). This MOSFET removes the risk of burnt contacts and noticeably improves your rifle's performance by increasing the rate of fire (ROF) and extending battery life. This specific version comes with a complete pre-made wiring harness, ready to install with the battery in the stock – no soldering needed!

Benefits of the JeffTron V2 MOSFET

• Higher rate of fire: The unit sends power directly to the motor, which reduces resistance in the system and gives faster trigger response.
• No sparks: MOSFET technology eliminates arcing at the contacts, which means you never again have to worry about worn or burnt trigger contacts.
• Water-repellent protection: The circuit board has a special coating that protects the electronics from water and moisture in the field.
• Heavy-duty construction: Designed to handle springs up to M170. It can cope with extreme loads (up to 90A in semi or 35A in burst for 30 seconds).

Easy drop-in installation

This kit is made to keep the upgrade as simple as possible:

• No soldering: The wiring comes pre-fitted with a Deans T-plug for the battery and faston connectors for the motor.
• Right length: The harness between gearbox and battery is 290 mm, which suits all gun types with the battery in the stock.
• High quality: Uses 1.3 mm² (AWG16) power cables with Teflon insulation for maximum durability and low resistance.

Technical specifications

• Compatibility: Standard V2 gearbox (Tokyo Marui standard).
• Battery support: Supports up to 17V (Ni-xx 8.4V – 12V and LiPo 7.4V – 14.8V).
• Power draw: Uses no power when the rifle is not in use (idle mode).
• Trigger: Built on SHS trigger contacts for high reliability.
• Connector: Fitted with Deans T-plug.
