Genuine AMASS 3.5mm Gold Plated Cross Bullet Banana Connector - High-Current ESC to Motor Plug (Pair)
The AMASS 3.5mm Bullet Connector is a high-performance gold-plated connector set engineered for low resistance and high reliability. With a current rating of 35A continuous, it is the perfect solution for connecting brushless motors to ESCs, allowing for easy motor swaps and maintenance without resoldering.
In the 2026 UAV ecosystem, power efficiency is paramount. These AMASS connectors utilize a 24K gold-plating process over high-purity brass to prevent oxidation—the leading cause of "dead-phase" motor failures in humid Indian climates.
Key Technical Advantages:
Cross-Slotted Tension System: The male connector features four precision-cut slots that act as springs. This ensures that even after hundreds of plug-cycles, the connection remains tight and maintains maximum surface contact to prevent arcing.
Low Internal Resistance: Optimized for high-frequency PWM signals, these connectors ensure that the timing and power from your ESC reach the motor with zero noticeable latency or voltage drop.
Compact Footprint: The 3.5mm size provides a massive current-to-weight ratio, making it small enough to hide inside slim carbon fiber arms or aerodynamic motor pods.
Easy Solder Cups: Features large, pre-tinned-compatible solder cups that make it easy to secure 14AWG to 16AWG wires for a professional, flush-mount finish.
Durable Construction: Built to withstand the extreme heat of soldering and the physical stress of "high-G" flight environments common in FPV racing and commercial mapping.
FAQ: Top 5 Questions on AMASS 3.5mm Bullets
Q1: Why use 3.5mm bullets instead of soldering the motor directly to the ESC?
A: Bullet connectors allow for quick maintenance. If a motor burns out or you need to reverse the direction of rotation in the field, you can simply swap the plugs instead of needing a soldering iron.
Q2: Will these fit 4.0mm or 2.0mm bullet connectors?
A: No. Bullet connectors are size-specific. 3.5mm male plugs will only fit 3.5mm female sockets. Always check your motor's pre-installed connector size before ordering.
Q3: How much heat shrink do I need to cover these?
A: We recommend 4mm or 5mm Heat Shrink for 3.5mm bullet connectors. This ensures the entire metal surface and the solder joint are insulated to prevent short circuits.
Q4: Can I use these for my battery connection?
A: While they can carry the current, it is not recommended for batteries. Using individual bullets for batteries risks accidental short circuits or reverse-polarity plugging. Use XT60 or XT90 housings for battery leads.
Q5: How do I get the strongest solder joint on these?
A: Clamp the connector in a "Helping Hand" tool with the cup facing up. Heat the connector cup itself with your iron, fill it halfway with solder, then dip the pre-tinned wire into the molten pool.
Expert Guide Question: Are you using these for 2207-sized FPV motors or a larger fixed-wing motor? Depending on your peak amperage, I can help you decide if 3.5mm is sufficient or if you should step up to 4.0mm bullets to prevent heat buildup during long-duration flights!
