Description
BEP DVSR 710-140A | Boat Supply Store
Protecting your engine start battery from accessory loads is critical for reliable vessel operation. This relay intelligently combines battery banks when a charging source is detected, ensuring your primary start battery remains robust for engine ignition. Its advanced digital circuitry offers extremely low power consumption, drawing zero standby current when configured with a storage mode switch, a significant advantage for vessels undergoing extended periods of inactivity. Ideal for offshore fishing boats requiring independent power for electronics and starting capabilities.
Key Features
- Safely charges two or more independent battery banks from one charge source
- Prioritizes engine starting batteries before combining auxiliary bank for charging
- Protects start batteries from being flattened by domestic loads
- Isolates electronics from harmful electrical surges from starter motors
- Simple to install 3-wire connection leaves alternator wiring intact
- No volt drop vs diode isolators
- Ignition protected for safe operation in engine spaces
- Multi-voltage, auto-selects between 12 and 24V DC operation

Reports of premature failure are not widespread, and the BEP DVSR is generally considered reliable. Proper installation and adherence to system voltage specifications are key to ensuring longevity.
Is the upfront cost justified compared to simpler relays?
The digital circuitry and advanced features, such as extremely low power consumption and intelligent remote sensing, provide superior performance and reliability compared to simpler mechanical relays, justifying the investment for critical battery management.
Frequently Asked Questions
How does the BEP DVSR 710-140A automatically manage battery banks?
The DVSR monitors the voltage of the engine start battery; when it reaches a predetermined charging level, the relay connects the auxiliary battery bank to the charging source, and disconnects them when the voltage drops below a set threshold.
What is the voltage range for the BEP DVSR 710-140A?
This unit operates automatically across both 12V and 24V DC systems, making it versatile for a wide range of marine electrical configurations.
Can the BEP DVSR 710-140A be used with both 12V and 24V systems?
Yes, the DVSR features multi-voltage capability and auto-selects between 12V and 24V DC operation, simplifying installation in mixed or future system upgrades.
What are the benefits of using a digital voltage sensing relay over a traditional diode isolator?
Digital voltage sensing relays, like this unit, have virtually zero voltage drop, unlike diode isolators which can reduce charging voltage and efficiency, and often feature lower standby power consumption.
Does the BEP DVSR 710-140A protect my engine start battery from being drained by accessories?
Yes, it prioritizes the engine start battery, ensuring it is charged before combining auxiliary battery banks and preventing domestic loads from depleting the start battery needed for engine ignition.
