The Redodo Dual Battery Isolator is a voltage sensitive relay that lets one alternator charge a starting battery and a house battery at the same time. It cuts in at 13.4V and cuts out at 12.8V, and the connect and disconnect thresholds are adjustable so it works on 12V or 24V systems with lead-acid or LiFePO4 batteries. A built-in LCD shows live voltage and current, and a button-driven emergency switch lets the house battery push charge to the starting battery for 60 seconds. It suits RV, marine, off-road and dual-battery vehicle owners who want one unit that covers both voltages; fixed-threshold VSRs are simpler and cheaper but cannot be tuned to a lithium charge profile.

The Redodo 12V/24V 150A Adjustable Dual Battery Isolator is a voltage sensitive relay (VSR) that charges two battery systems from one alternator. By default it cuts in at 13.4 volts and cuts out at 12.8 volts, which keeps the starting battery charged and ready to start the vehicle.
The connect and disconnect voltage thresholds are adjustable. This lets it work with 12V or 24V systems and with lithium (LiFePO4) and lead-acid batteries. For example, the working voltage can be set to match LiFePO4's 14.4V±0.2V. A built-in LCD display shows real-time voltage and current.
An emergency reverse charge switch is controlled by a button. If the house battery's voltage is higher, it charges the starting battery for 60 seconds so the engine can be started when the starting battery is drained. Protection includes over-voltage, over-temperature and reverse-current safeguards. The design is compact and tool-free, with standardized wiring, for cars, trucks, ATVs, RVs and marine systems.
