The Renogy Copper Battery Interconnect Cable is designed to efficiently link batteries in either series or parallel configurations using 5/16" M8 lugs, offering flexibility in your solar power setup. Crafted with quality in mind, this cable is UV resistant and waterproof, meeting TUV standards for solar use, ensuring its durability and reliability even in challenging outdoor conditions. The addition of heat-shrink tubing enhances safety, providing resistance against water and abrasion. Moreover, the cable features tin-plated copper, which not only enhances electrical conductivity but also contributes to effective heat dissipation, maximizing wire performance overall.
With this interconnect cable, you can optimize the connectivity and heat dissipation in your solar battery system, ensuring efficient and reliable operation. Connect your batteries in series (x1) or parallel (x2) with the Renogy high-quality battery cables. Specialized with 5/16'' tin-plated copper lugs on both ends, it provides abrasion resistance and electrical safety for your system.

| Series Connection |
To connect a group of batteries in series, you connect the negative terminal of one battery to the positive terminals of another, and so on until all batteries are connected. Wiring batteries together in series will increase the voltage while keeping the amp hour capacity the same. For example: 2 x 12V 100Ah batteries wired in series will give you 24V, but only 100Ah capacity.(24V*100AH=2400WH=2.4kwh) |
| Parallel Connection |
When connecting batteries in a parallel, the negative terminal of one battery is connected to the negative terminal of the next and so on through the string of batteries. Wiring batteries together in parallel has the effect of doubling capacity while keeping the voltage the same. For example: 2 x 12V 100Ah batteries wired in parallel will give you only 12V, but increases capacity to 200Ah. (12V*200AH=2400WH=2.4kwh) |
| Series/Parallel Connection |
Series-parallel connection is when you connect a string of batteries to increase both the voltage and capacity of the battery system. This is a combination of the above methods and is used for 2V, 6V or 12V batteries to achieve both a higher system voltage and capacity. For example: 4 x 12V 100Ah batteries can be wired in series /parallel to give you 24V with 200Ah capacity. (24V*200AH=4800WH=4.8kwh) |

What Is the Battery Cable For?
Renogy battery interconnects are designed for linking batteries together in a series/parallel connection.
How to Connect 2 Batteries in Series?
To connect two batteries in series, you should connect the negative terminal of one battery to the positive terminal of the second battery.
How to Connect 2 Batteries in Parallel?
When connecting two batteries in parallel, you will need two cables. Use the first cable to connect the negative terminal of one battery to the negative terminal of the second battery. Use the second cable to connect the positive terminal of one battery to the positive terminal of the second battery.
Does the Length Matter?
When connecting batteries in series or parallel, it's important that the cables between each battery are of equal length. This ensures that all batteries in the system have the same amount of cable resistance, allowing them to work together equally.
Does It Come with One or a Pair of Cables?
The listing is for a single cable.
