Ensure the negative terminals from both the main and auxiliary batteries have been disconnected.
Note: Short circuiting of any wire to the body will cause damage to both the unit and the vehicle and will also void your warranty.
Mounting and Wiring Procedure:
- Using built in brackets, mount DBE140SF unit on firewall securely as high as possible away from heat and water. (See wiring diagram)
- Using 10mm2 automotive grade cable and 10-6 cable lug, connect POSITIVE to main battery. (100 Amp midi fuse recommended)
- Attach earth cable to chassis or motor based earth. (Scratch back to bare metal)
- Refer to USER INTERFACE – LED OPERATION for DBE140SF operation and enjoy your hassle free dual battery system!
- Note: Do Not connect winches, welders or inverters above 1000 Watts to Aux. battery.
Testing Procedure:
To check if the unit is operating, remove the Auxiliary Battery Cable from the Auxiliary Battery and install a test light between the earth and the Auxiliary cable. Start the vehicle engine and the test light should come on after 5 seconds or sooner.
Note: Some new vehicles may take some time before alternator activates. The alternator is wired via the ECU, which is wired via a temperature sensor. That means the engine needs to warm up first before the alternator starts charging. To do your test procedure you have to wait until the alternator activates before you can check whether of not it is charging.
LED LIGHT OPERATION DBE140SF |
Two LED indicators provide an extensive user interface showing operational and diagnostic display, as follows: |
Main battery greater than 12.8V. | ||
Main battery greater than 12.8V and charging auxiliary battery. | ||
Main battery less than 12.8V and auxiliary battery disconnected. | ||
Overload – auxiliary battery disconnected. DBE140SF will automatically re-connect when safe to do so. | ||
Over voltage – auxiliary battery disconnected. DBE140SF will automatically re-connect when safe to do so. | ||
Fault with vehicle electrical system – VPF Enabled. Please check your vehicle for faulty connections. DBE140SF will automatically re-connect when the vehicle fault has been rectified. |

Dual Battery Management System – DBE180-SX
Piranha’s DBE180-SX Electronic Isolator is a 180 Amp unit with full spike and surge protection and solar input to charge the auxiliary battery. With a plastic/nylon case, sealed relays and special coatings to resist corrosion and water damage, this is the toughest isolator Piranha has ever built.
The DBE180-SX Electronic Isolator is an ignition sensing isolator and is ideal for touring vehicles with multiple batteries or for those vehicles needing to provide charge to batteries in camper trailers or caravans.
New Features:
VPF – Vehicle Protection Function Protects against overloads and faults.
Sense Function – Can operate using ignition sense or auto function.
100 Watt Solar Panel Input – Quick Connection from your Regulated Solar panel to your Auxiliary battery.
Diagnostic indicators – LED indicates Charging, non charging and fault modes.
Advanced Electronics:
- Fully automatic operation using advanced electronics and high performance relays. The electronics are rated for tough 4WD conditions and the relays are sealed against dust and moisture.
- High accuracy electronics manage the auxiliary battery for both effective charging and safe starting.
- The main starting battery is always protected and cannot be drained by a load connected to the auxiliary battery.
- Electronics are factory calibrated – no adjustments are required for the life of the unit.
- Efficient low power design offers maximum charging current for the auxiliary battery.
- New intelligent current limiting circuitry isolates auxiliary battery on accidental overload
- Improved electrical spike and surge protection.
Easy to use:
- New design with secure internal connection of battery cables
- simple to install. All wires, including two 3m heavy duty high quality heat and oil resistant cables with built in strain relief are provided.
- Easily mounted to engine bay or firewall
- Large LED indicator provides clear feedback to the user
- Manufactured in Australia to ISO9002 manufacturing standards
More Convenient:
- Output for remote monitoring auxiliary battery
- Input for auxiliary battery charging with regulated solar panels
(100 Watts MAX) - Convenient snap-fit connectors
Warranty:
Comes with a super 2 year warranty. 5 years if fitted by authorised Piranha agent.

Click HereMounting and Wiring:
- Mount the isolator high up in the engine bay away from moisture and any source of external heat (e.g. Exhaust System).
- Make sure that the cable entry holes and the isolator are pointing downwards.
- For Ignition Sense Function – Connect WHITE wire to a 12 Volt ignition switched power source (12V side of ignition switch or wiper motor circuit).
- For Battery Voltage Sense Function – Connect BLACK & WHITE wire to a good engine or chassis EARTH.
- Connect the marked main battery cable to the positive terminal of the MAIN battery. For the isolator to function properly, the MAIN battery voltage must achieve at least 13.4V when the engine is running in its normal state.
- Connect the AUXILIARY battery cable to the positive terminal of the AUXILIARY battery.
- Ensure AUXILIARY battery is correctly earthed.
Testing Procedure:
After mounting and wiring, to test if the unit is operating:
- Remove the AUXILIARY cable (check writing on cable) from the AUXILIARY battery.
- Install test light between AUXILIARY cable and EARTH.
- Start the vehicle.
- The test light should come on as soon as the main battery voltage exceeds 13.4 Volts. This could be within 1 sec. to 6 min. and the LED on the isolator should be GREEN. If not, check that the voltage of the MAIN battery is at least 13.4V.

Vehicle Protection Feature (VPF). The “VPF” function is there to protect your vehicle electrics and may indicate:
After rectifying problem, reboot the DBE180-SX by disconnecting power in and out and disconnect small earth and ignition wire. Wait 10 minutes and reconnect. Unit will reboot and go to green. |

WARNING:
- Do Not exceed the 5A limit when connecting a device to the Auxiliary Battery position of the DBE180-SX 4-terminal connector. Exceeding the 5A limit will cause damage to the DBE180-SX.
- Winching may overload your vehicle’s alternator and charging system. Do Not winch from the Auxiliary Battery! Consult the owners maual of the winch. A dual battery kit does not necessarily protect you from overloading the vehicle’s charging system. Consult your Piranha dealer for specific information on this issue.
- If using DBM4 battery protector with the low voltage cut out – it is necessary to follow the DBM4 protector wiring diagram precisely.
very clear and good article easy to understand. Thank you
