Specifications

To make reliable and durable electrical connections, battery cables will need to be made to the correct length. Reducing the wires or cables’ lengths properly will help to avoid unexpected voltage drops and noise. Cable lugs should be crimped and insulated to the cable before connection to the brass posts and spade terminals.

Minimal cable size for wiring up to 12m:

FREQUENTLY ASKED QUESTIONS

1. Is IDCX waterproof?

The IDCX was designed and engineered to the stringent ingress protection rating of IP68 & IP69K. This allows the IDCX to meet the toughest of challenges whether that be river crossings, engine bay washing or direct high pressure  washing of the unit.

2. Why do the positive cables from the batteries need to be fused?

High-Capacity batteries can produce large amounts of power and are capable of melting cable insulation and catching fire in the case of a short circuit. Each positive (+) cable connected to the battery must be protected by a fuse located in close proximity to the battery.

3. Is the IDCX safe to use with modern ‘electronic’ vehicles?

The IDCX has been designed to work with all vehicles, including new vehicles with EFI and computer management systems. The charger utilises sophisticated electronics that ensures complete safety for you and your vehicle.

4. How do I know if the battery is charged?

Refer to diagram “LED BATTERY CHARGE STATUS INDICATORS” on page 13 to identify when the IDCX is indicating battery charging is complete.

5. I have connected the IDCX properly but the power LED (lightning bolt) does not come on?

Check the cable size. The IDCX is designed to power on and charge from an input source as little as 9V. If small size cables are used for wiring, the voltage might drop below 9V when IDCX is attempting to start up. Please refer to Installation – wiring section for recommended cable size.

6. I have connected the IDCX to solar and alternator inputs, but LEDs do not come on?

In some cases batteries can be discharged to the point where they have very little or no voltage. This can occur if a small amount of power is used for a long time, for example a map reading light is left on for a week or more. The IDCX is designed to charge an auxiliary battery from as little as 2 Volts. Refer to Page 13 Output Override for detailed instruction.

7. Why is my IQD2 showing ‘No Device Found’ though all wires, including LIN, are connected properly?

IQD2 and IDCX may have malfunctioned. To resolve, remove and after about 1minute,  reconnect ALL power wires (IQD2 loom, ALT, Solar Neg, and Aux) on  IQD2 and IDCX.

8. Why is my IQD2 showing ‘No Device Found’ though all wires, including LIN, are connected properly?

IQD2 and IDCX may have malfunctioned. To resolve, remove and after about 1minute,  reconnect ALL power wires (IQD2 loom, ALT, Solar Neg, and Aux) on  IQD2 and IDCX.

9. How do I make my IDCX LED indicate the same battery chemistry compared to my IQD2 Mobile App?

Sometimes, when battery chemistry is changed by pressing the IDCX button, it does not reflect it to the Mobile App. To force the Mobile App to sync to IDCX, close IQD2 Mobile app then reconnect.

10. Why is Battery not getting charged though solar input voltage is within range?

Solar input voltage is not an indicator of the Solar panel capability. Weather may be cloudy or solar panel is under the shade and the input current is not enough to commence charging.

11. Why is LED flashing amber though my battery is connected?

While IDCX is in the process of recognizing (about 2minutes) the  battery, LED is in amber state. It is also in the same color if battery is not present or battery voltage is very low. To regain charging a battery that is very deeply depleted, press and hold the IDCX button for about 10 seconds.

12. Why does the IDCX indicate the battery is fully charged straight away?

There are three possible reasons why the IDCX indicated the battery is fully charged. 1. The battery is fully charged. 2. The battery has taken a surface charge. 3. The battery has a faulty cell.

13. What is a “Surface Charge”?

Batteries unused or left discharged for some time build up a resistance to being recharged. When the charger is first connected, these batteries will take a surface charge, and the IDCX LED’s will indicate the auxiliary battery is fully charged within a short period of time. The battery however is not fully charged. The charger is voltage sensitive and cannot differentiate between a surface charge and a fully charged battery. After a few hours, the battery may start to accept some charge but most batteries with this condition may not recover.

14. What is a “Faulty Cell”?

12 Volt batteries contain 6 cells, and one faulty cell is enough to ruin your battery. If after twelve hours of charging your battery is still accepting charge, you should test the cells using a hydrometer. If one reading is lower than the rest, it indicates a faulty cell. It is pointless to continue charging; the battery needs replacing.

15. Why is there no output at the IDCX’s auxiliary battery output? 

The IDCX incorporates short circuit protection that makes it much safer to use. For this reason, the IDCX will only output power when properly connected to a battery. To check if the IDCX is functioning, follow the instructions to connect and operate the charger as normal on a flat battery. While the battery is charging measure the battery voltage with a volt or multi-meter. Charging can be confirmed if the voltage is increasing (within the voltage parameters set out in the specifications).
