CAR AUDIO AND AUXILIARY BATTERY CONNECTION

Heavy-Duty Multi-Cable Battery Terminal Connector Set — Positive and Negative Pair | Multi-Gauge Cable Entries | Tapered Battery-Post Mounting

DAIERTEK BT-02 is a heavy-duty positive-and-negative battery terminal set for organizing several cable connections directly at a vehicle battery. Its multi-entry architecture is intended for car audio, auxiliary power and aftermarket electrical installations where one battery post must accept conductors of different sizes. The terminal bodies use a conductive alloy construction and are supplied with positive and negative post interfaces. Published product information identifies 19 mm positive and 17 mm negative connections together with copper spacer sleeves, helping the set adapt to compatible tapered battery posts. BT-02 is a common electrical connection point and does not provide branch-circuit isolation or fusing. Cable allocation, conductor size, stripping length, set-screw torque, polarity and overcurrent protection must be defined for the completed installation.

Product Details

  • 01 Multiple conductor entry sizes
    The stepped cable-entry layout supports compatible large main conductors and smaller auxiliary conductors within one terminal body. Assign each entry by cable size and circuit function before installation.
  • 02 Positive and negative terminal pair
    Dedicated positive and negative pieces support a complete battery connection layout. The different tapered-post diameters must be matched to the correct battery polarity.
  • 03 Set-screw cable retention
    Individual set screws retain prepared conductors in the terminal body. Cable preparation, tightening torque and strain relief must follow the approved installation requirements.

Use a direct terminal or adapter when the connection starts at the battery. Use a remote post when the battery connection must be brought to an accessible panel or service point.

Applications

Car audio battery wiring

Organize amplifier power, auxiliary feeds and compatible main battery cables at a defined battery-terminal interface.

Aftermarket accessory installations

Consolidate several compatible vehicle accessory conductors while maintaining a clear cable map and separate circuit protection.

Custom vehicle electrical systems

Provide a reusable multi-cable terminal architecture for off-road, fleet and special-purpose vehicle builds.

Application examples describe potential use cases, not verified fitment to a particular vehicle. Confirm polarity, cable size, protection, mounting space, environmental exposure and the approved service procedure before installation.
