• Craft Standard

1. Integrated high-pressure crimp between wire and banana terminal, strong pull resistance, wire will not fall off under violent vibration
2. Bare wire end full tin dipping to prevent copper wire scattering and short circuit

Core Product Features:

• Thick Gold-Plated 3.5mm Copper Terminals

Ultra-low contact resistance, effectively prevent overheating and melting under large drone operating current, anti-oxidation for long service life.

• High Temperature Silicone High-Current Wire

14/16AWG thick multi-strand wire bears 30A continuous current, soft silicone jacket resists motor high temperature, not easy to melt.

• Anti-Slip Insulated Red Plastic Housing

Safe isolation of positive and negative poles, prevent accidental short circuit; ribbed outer surface for easy plugging and unplugging.
Two Optional Versions: Double Plug / Single Open Wire
Double-head finished cable for direct motor-ESC plug connection; single-head bare wire for customer self-soldering on motors/batteries.

• Strong Vibration Resistance Crimp Craft

Tight terminal crimping structure, no loose contact during drone high-speed stunt flight, stable power output.

• Fully Customizable Service

Custom wire length, wire gauge, plug color, add heat shrink tube, OEM logo printing for drone factory bulk orders.
RoHS Compliant Eco-Friendly Materials
Non-toxic silicone and copper material, meets global export hobby electronic standards.

Important Notes:

1. Please confirm the connector model, pin sequence and wire gauge before installation to avoid wrong connection, short circuit or equipment damage.

2. Avoid using the wire harness in over-current, over-voltage or high-temperature exceeding the rated working range, to prevent wire heating and safety risks.

3. Keep the connector away from water, dust, oil and corrosive environments to ensure long-term stable conductivity and avoid poor contact.

4. Do not bend or squeeze the wire sharply for a long time; reasonable wiring protection can extend the service life of the harness.

5. For drone and flight model applications, check the locking buckle condition before flight to ensure firm connection and prevent mid-air disconnection.
