Genuine AMASS 3.5mm Gold Plated Cross Bullet Banana Connector - High-Current ESC to Motor Plug (Pair)
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!
