Review BSTENKY Dual Battery Isolator Kit 12v 140amp Split Charge Relay Smart Manual/auto

The BSTENKY HML126 Dual Battery Isolator Kit is an essential accessory for any vehicle or off-grid system that utilizes two batteries for different purposes, such as a starting battery and a deep cycle battery. This kit comes with everything you need to effectively manage and charge both batteries, including a pair of 140-amp split charge relays, wiring harnesses, a mounting bracket, and installation hardware.

The heart of this system are the two heavy-duty, 140-amp split charge relays. These relays allow the alternator to charge both batteries simultaneously, but also provide the ability to prioritize charging one battery over the other depending on the needs of your system. This is particularly useful when one battery is fully charged, as it prevents overcharging and ensures the longevity of both batteries.

The relays in this kit are smart, meaning they can automatically switch between charging modes based on the voltage of the batteries. When the starting battery reaches a fully charged state, the relay will switch to charge the deep cycle battery. This manual/auto switching feature provides flexibility and convenience, as you can also manually override the automatic switching if needed.

The wiring harnesses in the kit are designed to make installation as simple and straightforward as possible. They are color-coded and clearly labeled, ensuring that the correct connections are made during installation. The kit also includes a mounting bracket and installation hardware, allowing you to securely mount the relays in a convenient location in your vehicle or off-grid system.

Overall, the BSTENKY HML126 Dual Battery Isolator Kit is a high-quality, versatile, and easy-to-install solution for managing and charging multiple batteries in a single system. It is suitable for a wide range of applications, from automotive use to off-grid power systems, and is built to withstand the rigors of frequent use in harsh environments. With its smart, manual/auto switching relays and user-friendly installation process, this kit is an excellent investment for anyone looking to optimize their battery management system.
