Mini 2mm bullet connectors
Mini 2mm Bullet Connectors give your combat robot fast, reliable wiring connections. Their gold-plated copper design minimizes resistance, resists oxidation, and delivers consistent current flow. A secure, positive fit keeps connections locked during battle—no accidental disconnects. Perfect for quick swaps at events, you can replace motors, batteries, or ESCs without soldering under pressure. Truly plug-and-play connectors for when every minute counts.

Overview
Mini 2mm Bullet Connectors are the compact, gold-plated connectors trusted in competitive combat robotics. They’re the same quick-connect solution used on Repeat Robotics plug-and-play drive motors (set up for the Saifu Combat Robot Kit) and the Repeat Plug-and-Play Dual ESC powering the Saifu Antweight Kit. That means builders can field-swap motors, batteries, or ESCs without ever touching a soldering iron—an absolute advantage when time between matches is short.
The gold-plated copper contact surfaces minimize resistance, resist oxidation, and maintain a reliable current path. Their firm “snap-fit” connection won’t shake loose during high-energy hits, yet still allows fast disconnects when needed. These connectors are truly plug-and-play for combat robots—get back in the arena faster, with confidence that your wiring will hold.
Why Choose Mini 2mm Bullets?
- Trusted in competition: standard on Repeat Robotics motors and ESCs, used by builders in the Saifu antweight kit.
- Quick serviceability: swap components in seconds without re-soldering under pressure.
- Secure fit: strong enough to stay locked during combat impacts.
- Efficient power transfer: gold-plated copper keeps resistance low and current high.
- Compact size: perfect for Antweight and Beetleweight robots where space and weight matter.
Typical Applications
- Motor ↔ ESC phase connections (e.g., Repeat 16mm drive motors)
- Battery leads on smaller packs
- Quick-swap wiring in pits or test benches
Historical Note
Bullet connectors were first popularized in RC cars and drones for their low-resistance, high-amperage capability. Combat roboticists quickly adopted them for the same reason: reliable power under shock loads. Today, 2mm bullets are almost the “standard issue” for Antweights—compact, tough, and proven in hundreds of fights.
Features
- Gold-plated copper for high conductivity and corrosion resistance
- Firm connection that won’t separate in combat
- Plug-and-play—fast swaps without re-soldering
- Standardized on Repeat motors and Repeat Dual ESC (Saifu ecosystem)
- Compact and lightweight—ideal for Antweights
Overview
Mini 2mm Bullet Connectors are compact, gold-plated connectors trusted in competitive combat robotics. They’re the same quick-connect solution used on Repeat Robotics drive motors (link coming soon) and the Repeat Plug-and-Play Dual ESC in the Saifu Antweight Kit—so you can swap motors or ESCs without touching a soldering iron between matches. Gold-plated copper contacts minimize resistance, resist oxidation, and maintain reliable current flow. The firm snap-fit stays put through hard hits yet disconnects quickly for service. When every minute counts, these connectors keep your wiring modular and fast.Why Choose Mini 2mm Bullets?
- Used in Saifu: standard on Repeat motors and the Repeat Dual ESC for solderless quick-connects.
- Rapid serviceability: swap motors or ESCs in seconds—no re-soldering under pressure.
- Secure fit: connection won’t shake loose in combat.
- Low electrical loss: gold-plated copper helps keep resistance down and current up.
- Small and light: ideal for Antweight and tight packaging.
Typical Applications
- Motor to ESC wiring on Repeat drive systems (as used in Saifu)
- Quick-swap service harnesses and pit repairs
- Bench testing and modular wiring assemblies
Installation Tips
- Prep the wires: strip, twist, and tin; lightly tin the connector cup.
- Heat quickly: fill the cup, insert the tinned wire, let it flow—avoid lingering heat that can relax the spring fit.
- Insulate: use heat-shrink (3mm) on each joint to prevent shorts.
- Heat-shrink placement: extend tubing to the edge of the mating surface for full insulation, but not past it—connectors must seat completely together.
- Strain relief: support wires so impacts don’t lever the solder joint.
- Final check: perform a firm tug test; the connection should snap in and resist vibration.

Historical Note
Originally popular in RC for high-current, compact connections, bullet connectors were adopted by combat robotics for their durability under shock and their service speed. Mini 2mm bullets have since become a go-to for Antweights where modular, lightweight wiring is critical.Specifications
