A smart isolator is the ultra-simple and most technologically advanced method of automatic battery isolation. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation when a charging source is unavailable. The small size and rugged construction of these units allow for quick simple installation for even the most novice DIYer. The smart isolator is also “Dual Sensing” which senses the charge of both batteries. If either battery is receiving a charge, e.g. a battery charger is connected to the auxiliary battery; the relay will engage and charge both batteries. The advanced technology always insures that the first battery is fully charged (13.4v) before connection is made to the second battery. This prevents problems that may result from your charging source being too low in amps to charge all batteries as once. If placed in linear sequence between each battery the isolator units can provide proper charging for several batteries in a multiple battery setup such as in larger boats that may have 2 or more house batteries. How it works: The smart isolator allows two batteries to be charged at the same time. When the engine is started and either battery reaches 13.4 volts, the relay engages, allowing two battery banks (start and accessory) to be charged simultaneously. When the voltage drops below 12.9 volts (eg the engine is stopped), the relay disengages, separating the batteries. This system eliminates the possibility of draining the start battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.

Frequently Asked Questions
Q: What is a smart dual battery isolator and how does it work?A: A smart dual battery isolator is a device designed to automatically control the charging of two batteries while providing isolation when needed. It allows both batteries to be charged simultaneously when either reaches 13.4 volts, ensuring the primary battery is fully charged before connecting the second battery. This prevents overloading and ensures efficient charging.
Q: Is the smart isolator compatible with all types of vehicles?A: Yes, the smart dual battery isolator is versatile and can be used in various vehicles, including cars, boats, and RVs. Its compact size and simple installation make it suitable for most setups, ensuring that it can be integrated easily without bypassing existing alternator wiring.
Q: How easy is it to install the smart dual battery isolator?A: Installation is straightforward and can be done by even novice DIYers. The isolator comes with detailed instructions and all necessary mounting screws. Its compact dimensions (2.68" x 2.68" x 1.93") and water/dust resistance allow for flexible placement in your vehicle.
Q: What features differentiate this smart isolator from conventional diode isolators?A: The smart dual battery isolator offers no voltage drop during operation, unlike conventional diode isolators that incur a minimum drop of 0.6 volts. This ensures efficient charging without loss of power, making it a superior choice for maintaining battery health and performance.
Q: Can I use this isolator with multiple batteries in a larger setup?A: Yes, the smart dual battery isolator can be used in configurations with multiple batteries. When placed in linear sequence between batteries, it effectively manages the charging process for several batteries, making it ideal for larger setups such as in boats with multiple house batteries.
