Wire harness, parallel battery connection

Connect your batteries in parallel with the Wire Harness TRX-3064

The Wire Harness TRX-3064 is the wiring harness specifically designed to make parallel battery connections cleanly, safely, and without the need to modify the original wiring of the system. A straightforward solution for those who need to expand their battery capacity while maintaining the electrical integrity of the setup.

Function and performance

Connecting batteries in parallel allows for maintaining the nominal voltage while doubling (or increasing) the total capacity in milliamp hours (mAh). This harness facilitates that operation with pre-prepared wiring, avoiding improvised splices that can lead to efficiency losses or short-circuit risks.

• Factory-prepared wiring for parallel connection.
• Maintains constant voltage when combining batteries.
• Reduces the risk of errors in manual wiring.
• Direct installation, no specialized tools required.

Assembly and preparation

Assembly is straightforward: simply identify the correct terminals of each battery and connect the harness following the indicated polarity. As it is a prefabricated harness with the reference TRX-3064, the connectors are designed to fit precisely, minimizing the margin of error during installation.

We recommend always verifying that the batteries to be connected are of the same type, voltage, and, if possible, with a similar charge level before making the parallel connection. This prolongs the lifespan of both cells and ensures stable electrical behaviour.

Considerations

As with any parallel battery connection, it is important to respect polarity and ensure that the batteries are compatible with each other. Do not mix batteries of different chemistry or widely varying capacities, as this could create an unwanted compensation current between them.

Frequently asked questions

What is the purpose of a parallel connection wire harness?

It allows you to join two or more batteries in such a way that they share the same voltage but sum their individual capacities. The result is greater autonomy without increasing the system voltage.

Is it compatible with any battery?

The TRX-3064 harness is designed to integrate into systems with the specific connectors of its reference. Before installing it, check that the terminals of your batteries match those of the harness.

Do I need to solder anything to install it?

No. As a prefabricated harness, installation is done through direct connection of the connectors, without the need for soldering or electrical tools.

Can I use batteries of different capacities with this harness?

Technically it is possible, but it is not recommended. Batteries with different capacities tend to become unbalanced during charge and discharge, which can reduce their lifespan. Ideally, use batteries of the same model and charge state.

Does this harness affect the total voltage of the setup?

No. The parallel connection keeps the voltage equal to that of a single battery; what increases is the total available capacity (mAh).

The TRX-3064 wire harness for parallel battery connection is a reliable and ready-to-use wiring solution designed to safely join batteries in parallel, increasing total capacity while keeping voltage stable. Ideal for RC models, slot car power setups, and any hobby application requiring extended battery runtime without complex wiring modifications. Easy to install, no soldering required.
