Manage high-amperage power transfers with professional reliability using our 300A Heavy-Duty Copper Battery Clips. These 14cm alligator-style clamps are designed for the most demanding environments, from heavy machinery jump-starting to high-capacity industrial battery maintenance.
Each clamp features thick copper internal jaws that provide a superior electrical contact area, ensuring maximum conductivity and heat dissipation during high-current use. For total operator safety, the clips are fully encased in rugged, high-impact PVC insulation that covers the entire metal body. The ergonomic handles include deep ribbing for a secure, non-slip grip, even when working with oily hands or heavy work gloves.
300A Industrial Rating: Engineered to handle high-surge currents required for starting large diesel engines and industrial generators.
Full-Body Insulation: Comprehensive red and black PVC shrouding prevents accidental short circuits and provides safe handling.
Professional 14cm Size: The extended 14cm frame offers massive leverage and a wide jaw opening for the largest battery terminals.
Pure Copper Contact: High-surface-area copper jaws minimize resistance and voltage drop under heavy loads.
Ultra-High Tension Spring: A reinforced internal spring ensures the clamps bite through corrosion for a permanent, stable connection.
Current Rating: 300 Amperes.
Total Length: 140mm (14cm).
Contact Material: High-conductivity copper.
Insulation Material: Heavy-duty, weather-resistant PVC.
Quantity: 1 Pair (1x Red Positive, 1x Black Negative).
Grip Design: Ergonomic deep-ribbed handles for maximum control.
Heavy Vehicle Jump-Starting: Ideal for building custom booster cables for trucks, tractors, and construction equipment.
Off-Grid Solar Banks: Connecting high-capacity 24V or 48V battery arrays for backup power systems.
Fleet Maintenance: Heavy-duty replacement clamps for professional garage and workshop battery chargers.
High-Power Inverters: Providing a secure, low-resistance tap for high-wattage DC-to-AC power inverters.
Can these handle continuous high-current use?
Yes, the 300A rating and thick copper jaws are specifically designed to manage sustained high-amperage loads without excessive heat buildup.
How is the cable attached to the clip?
The internal metal frame features a dedicated mounting point at the rear of the handles for heavy-gauge wire, which can be securely bolted or soldered.
Are the springs strong enough for vertical terminals?
Absolutely. These clips utilize industrial-grade high-tension springs that provide a "locked-on" grip, even on smooth or vertical battery posts.
