High-Current Battery Connection Cable (Battery Jumper Cable / Battery Series Connection Cable)

Product Features

1. High-Conductivity Pure Copper Terminals: Stamped from premium copper material with smooth and burr-free surface. It delivers excellent conductivity and effectively reduces current transmission loss to meet high-current requirements. Clear specification markings on terminals facilitate model selection and installation.
2. High-Insulation & Temperature-Resistant Cable: The outer sheath is made of high-quality insulating material (PVC/TPE/Silicone optional), featuring resistance to high & low temperature, aging and oil contamination. With stable insulation performance, it can serve long-term in harsh environments and prevent electric leakage and short circuits. The cable core is made of high-purity copper conductor with low resistance and strong current-carrying capacity for stable current transmission.
3. Reinforced Safety Protection: The joint between terminals and cables is fully sealed with heat shrink tubing, which enhances insulation and tensile resistance. It prevents loosening and oxidation at connections to extend service life and ensure safer use.
4. Polarity Identification Design: Red and black cables clearly mark positive and negative poles to avoid reverse connection, lowering the risk of equipment damage caused by installation errors. Suitable for all common battery connection applications.
5. Strong Compatibility & Flexibility: Customizable wire gauge, cable length and terminal hole diameter. We can develop exclusive solutions according to equipment current demand, installation space and battery terminal specifications to satisfy diverse application scenarios.

Product Advantages

• Safe and Reliable: Premium materials and sealing protection technology effectively eliminate potential risks such as electric leakage, short circuit and arcing, adapting to harsh working environments of vehicles and marine equipment.
• Efficient Transmission: High-conductivity pure copper terminals combined with low-resistance copper core cables cause negligible voltage drop during high-current transmission, ensuring stable power supply and avoiding equipment malfunctions due to insufficient power.
• Durable & Sturdy: The insulating sheath resists extreme temperatures, aging and oil. Terminals feature excellent anti-oxidation and anti-corrosion performance. The cable can work reliably for a long time outdoors or in engine bays with longer service life.
• Easy Installation: Terminals fit standard battery bolts. Quick assembly can be realized without special tools. Red-black polarity marking also speeds up identification and installation.

FAQ

Q1: What is the maximum current this cable can carry?

A: Current capacity depends on wire gauge. Standard 10AWG carries about 30A, 8AWG about 50A, 6AWG about 80A and 4AWG about 120A. You may select the proper gauge based on your equipment’s current demand, and customized solutions are also available.

Q2: Can the terminal hole diameter be customized?

A: Yes. We offer terminals with various hole sizes to fit different battery bolts. Simply provide the bolt or terminal dimensions for customization.

Q3: Can I change the cable material?

A: Sure. PVC, TPE and Silicone are available as standard options. Silicone performs better under extreme temperatures, ideal for outdoor use and engine bays. PVC and TPE are more cost-effective for indoor and regular vehicle applications.

Q4: Can I order cables with non-standard lengths?

A: Yes. We customize any length from 10cm to 100cm and above to fit various installation spaces. Special specifications are acceptable for bulk orders.

Q5: Does this product come with a warranty?

A: Manufactured with high-quality materials and strict craftsmanship, the product is covered by standard warranty. After-sales service is provided for non-artificial quality issues. Please contact our customer service for detailed warranty terms.
