4.0mm Gold Plated Bullet Connector Male-Female Pair

Gold-Plated Brass Construction: Premium gold plating over high-conductivity brass minimizes contact resistance, resists oxidation, and ensures maximum power efficiency.

Heavy-Duty 4.0mm Banana Plug Profile: Large 4.0mm diameter contact area handles high continuous current draws, making it optimal for high-power RC cars, large drones, and electric vehicles.

Low-Resistance High-Current Transfer: Engineered for minimal power loss during peak discharge demands, ideal for high-amp ESCs (Electronic Speed Controllers), high-turn brushless motors, and LiPo batteries.

Spring-Mesh Tensioned Male Plug: Features expanded spring-mesh leaves on the male bullet connector to maintain a firm, low-resistance friction grip under heavy vibration.

Deep Solder Bucket Wells: Features extra-deep solder cups for quick wire tinning and smooth solder flow with heavy-gauge silicone wire (12AWG-14AWG).

Matched Male-Female Pair: Supplied as a complete set containing one male bullet connector and one female bullet socket for quick disconnect functionality.

Connector Body Material: High-conductivity gold-plated brass alloy.

Technical Specifications:

Connector Type: 4.0mm Bullet / Banana Plug (Male & Female Pair).

Gender: 1x Male Plug, 1x Female Socket.

Weight: $0.05\text{ kg}$.

Color: Metallic Gold.

Usage Advice: Heat the solder well directly with a medium-to-high wattage soldering iron, fill slightly with solder, and insert the pre-tinned heavy-gauge lead. Insulate connections with heat shrink tubing.

Maintenance: Keep contact surfaces clean of flux residue; wipe occasionally with isopropyl alcohol to preserve maximum conductivity.

Essential High-Power Power Interconnect: Position as a robust high-current connector pair for high-performance RC vehicles, large multirotor drones, high-power brushless setups, and custom battery power feeds.

Highlight Maximum Current Capacity & Low Resistance: Emphasize the 4.0 mm heavy-duty construction and anti-corrosion gold finish designed to withstand high current bursts without overheating or physical connection failure.

Recommended Cross-Sell Add-ons: Pair with 2.0mm Gold Plated Bullet Connector Male-Female Pair, 3.5mm Gold Plated Bullet Connector Male-Female Pair, XT60 Bullet Connector Pair, and ESD antistatic mat 50x40CM PCB Welding Mat.
