Product Description
Customer Questions & Answers
-
Question:
What is the purpose of the DEWINNER dual battery smart isolator?
Answer: The DEWINNER dual battery smart isolator is designed to manage and control two battery systems in vehicles like ATVs and UTVs. It uses voltage sensing technology to automatically engage or disengage based on battery levels, ensuring that your starting battery remains charged while allowing power to be drawn from the auxiliary battery for accessories. This prevents battery drain and extends battery life, making it ideal for off-road adventures where dual battery setups are common. -
Question:
How does the voltage sensitive relay (VSR) work in this isolator?
Answer: The voltage sensitive relay (VSR) operates by monitoring the voltage levels of the batteries. When the starting battery reaches a specific voltage, the VSR connects both batteries, allowing for charging. Conversely, if the starting battery's voltage drops below this level, the relay disconnects the auxiliary battery to prevent draining the starting battery. This functionality is particularly useful in situations where power consumption from accessories might otherwise deplete the starting battery. -
Question:
Is the wiring cable kit included in the DEWINNER product?
Answer: Yes, the DEWINNER 12V dual battery kit comes with a complete wiring cable kit. This makes installation more straightforward as it includes all necessary cables and connectors required for setting up the isolator. The included kit ensures compatibility and helps maintain proper electrical flow, making it convenient for users to set up their battery system without having to procure additional materials separately. -
Question:
Can this isolator be used in marine applications?
Answer: While the DEWINNER dual battery smart isolator is primarily designed for ATVs and UTVs, it can also be used in marine applications. Its robust design and reliable voltage sensitivity make it capable of handling the unique demands of boating, where dual battery systems help ensure that essential electrical systems have sufficient power while preserving the starting battery. It's essential to ensure proper waterproofing and installation for marine use. -
Question:
What types of batteries are compatible with this dual battery isolator?
Answer: The DEWINNER dual battery smart isolator is compatible with various types of 12V batteries, including lead-acid, AGM (Absorbent Glass Mat), and gel batteries. It's crucial to choose batteries that suit your power needs and usage habits. By pairing it with the right batteries, users can optimize the isolator's performance, ensuring reliable electricity for accessories while protecting the starting battery's charge. -
Question:
Can I install the DEWINNER isolator myself?
Answer: Yes, many users can install the DEWINNER dual battery smart isolator themselves, especially if they have basic electrical knowledge. The kit comes with a comprehensive wiring harness and clear instructions, making it user-friendly for those familiar with automotive electrical systems. However, for users less confident with DIY installations, seeking professional assistance is advisable to ensure safety and proper functionality. -
Question:
What are the safety features of the DEWINNER dual battery isolator?
Answer: The DEWINNER dual battery isolator includes several safety features, such as reverse polarity protection and short circuit protection, to safeguard both the vehicle and the batteries from faults. These features are crucial during operation, especially in rugged environments where electrical issues could arise due to vibration or environmental factors. Such protections help users have peace of mind when relying on their battery systems. -
Question:
How can I monitor the battery levels with this isolator?
Answer: The DEWINNER dual battery isolator does not come with a dedicated battery monitoring system; however, users can integrate external battery monitors or Smart Battery Monitor systems that provide real-time voltage readings. This combination allows users to effectively keep track of both starting and auxiliary battery levels, giving insights into their system's performance and ensuring that batteries maintain optimal charge for various applications. -
Question:
What common issues can arise if I don't use a dual battery isolator?
Answer: Not using a dual battery isolator can lead to multiple issues, such as battery drain where the auxiliary battery discharges at the expense of the starting battery, causing the vehicle to not start. Additionally, it can lead to overcharging or undercharging of batteries, which diminishes their lifespan and efficiency. Hence, using a dual battery isolator is essential for those wanting a reliable and efficient power management system in off-road situations. -

DEWINNER Battery Chargers Editorial Review
The Dual Battery Smart Isolator DEWINNER is a voltage-sensitive relay designed for use in ATV, UTV, boats, RVs, campers, 5th wheels, and off-road vehicles. The device is designed to detect the charge voltage from both batteries, and there is an LED on the face that is on when the unit has closed the circuit. The device should measure voltage at the batteries without regard to where the voltage is coming from. Some customers reported that the LED light does not work, and the unit did not work out of the box. One customer installed a second battery in a boat to isolate the starting battery from the accessories battery and claimed that it worked perfectly. Another customer used the device in a UTV, and it allowed the auxiliary battery to charge when the starter battery is at 12.3 V, killing two batteries in three months. Some customers took issue with the device being made in China and claimed that it did not work. The device should be installed with a fuse or other circuit protection right at the positive terminal of any battery.
