Customer Questions & Answers

  • Question: What is the purpose of the Nilight Dual Battery Isolator Kit?

    Answer: The Nilight Dual Battery Isolator Kit is designed to manage two batteries efficiently in vehicles, especially trucks. It allows for the dual battery system to charge simultaneously while isolating them during periods of inactivity to prevent drain. This system is particularly beneficial for off-roaders and those who use accessories that require additional power. It ensures that your primary battery remains charged for starting the vehicle, while the secondary battery can be used for high-demand accessories.
  • Question: How does the Voltage Sensitive Relay (VSR) work in this kit?

    Answer: The Voltage Sensitive Relay (VSR) in the Nilight kit monitors battery voltage levels to engage or disengage the connection between the batteries. When the primary battery reaches a certain voltage, the VSR allows charging of the second battery, ensuring it receives sufficient charge when the engine is running. Conversely, it disconnects if the voltage drops, protecting the starter battery from depletion. This intelligent operation makes it especially suitable for users who require reliable battery management during long trips.
  • Question: Can I install this isolator kit on my own?

    Answer: Yes, the Nilight Dual Battery Isolator Kit is designed for user-friendly installation. Provided with 6 AWG power cables and detailed instructions, it can be installed by someone with basic automotive knowledge. The process generally involves connecting the relay and cables to the batteries and the vehicle’s electrical system. However, for those unfamiliar with electrical installation, seeking professional assistance is advisable to ensure proper setup and functionality.
  • Question: What type of truck is this isolator kit compatible with?

    Answer: The Nilight Dual Battery Isolator Kit is compatible with a wide range of trucks, including those that have additional electrical needs such as off-road trucks, camper vans, and more. As long as the truck operates on a 12V electrical system, and the batteries are of appropriate size, this kit can be effectively utilized. It is especially useful for trucks outfitted with various accessories like winches, lighting, or sound systems that require extra power.
  • Question: Does this kit include everything I need for installation?

    Answer: Yes, the Nilight Dual Battery Isolator Kit includes a voltage-sensitive relay, 6 AWG power cables, and terminal connectors required for installation. These components are specifically selected to work together seamlessly, ensuring optimal performance. Additionally, the kit typically comes with a user manual to guide you through the installation process, making it straightforward to set up for enhancing your vehicle's dual battery system.
  • Question: What makes this isolator smart or automatic?

    Answer: The term 'smart' in the Nilight isolator kit refers to the advanced Voltage Sensitive Relay (VSR) that automatically monitors voltage levels. It intelligently disconnects or reconnects the batteries based on their charge state. This automation saves you the trouble of manually managing your batteries and ensures they are charged adequately, reducing the risk of battery drain when the vehicle is not in use. It’s a perfect fit for those who rely on auxiliary power without the hassle.
  • Question: Can I use this kit with AGM or Gel batteries?

    Answer: Yes, the Nilight Dual Battery Isolator Kit is compatible with various types of batteries, including AGM (Absorbed Glass Mat) and Gel batteries. These battery types are often used in applications that require deep cycling and prolonged power use, such as in RVs or trucks with significant accessory loads. It's essential to confirm that the batteries you are using match in voltage and capacity to ensure optimal operation.
  • Question: What tools do I need for installation?

    Answer: To install the Nilight Dual Battery Isolator Kit, you'll generally need a set of basic tools including a wrench set, wire cutters, and crimping tools. Depending on your truck’s setup, a multimeter can also be useful for diagnosing electrical connections. Following the provided instructions and using the right tools will make the installation process efficient and successful, adding functionality to your vehicle’s electrical system.
  • Question: Is there any maintenance required after installation?

    Answer: Minimal maintenance is required once the Nilight Dual Battery Isolator Kit is installed. It is advisable to periodically check all connections for corrosion, ensure the relay operates correctly, and confirm that battery terminals are clean. Keeping the kit well-maintained will extend its life and ensure reliable performance. In scenarios where the truck is frequently used for heavy electrical loads, regular check-ups may be beneficial.
  • Question: Where can I buy the Nilight 12V 140AMP Dual Battery Isolator Kit in The Bahamas?

    Answer: You can purchase the Nilight 12V 140AMP Dual Battery Isolator Kit from Ubuy in The Bahamas.

Nilight Battery Switches Editorial Review

The Nilight 12V 140AMP Dual Battery Isolator Kit has garnered a mix of positive and negative feedback from customers, with users broadly appreciating its functionality while expressing some concerns about the design and instructions. Many reviewers highlighted the device's effectiveness in managing dual battery setups, particularly for applications involving high power draw, such as running ham radios, inverters, or dash cameras without worrying about draining the primary battery. Users have described it as a "set and forget" solution that simplifies the process of maintaining battery life across multiple units, particularly in camping scenarios or off-road vehicles. However, some users faced challenges, particularly regarding the clarity of the installation instructions, indicating that new users may need to rely on online resources to fully understand the setup. Additionally, there have been reports of technical failures, with one user detailing that the product stopped functioning after a month. Concerns were raised about the size of the wire entry ports, making it difficult to connect larger gauge wires that can be necessary for robust battery systems. Overall, while many customers enjoyed using the Nilight Dual Battery Isolator Kit for its intended purpose, there are notable issues around durability and clarity of instructions that potential buyers should Consider. **
