Dual Battery Systems

Twin Charge
The Twin Charge Battery Charger is a major breakthrough for charging a second battery through the 12 volt system of a vehicle. Previously the only systems available to charge a second battery from a vehicle were solenoid, diode or percentage switching systems. Unfortunately all of these systems can reduce battery life, due to failure to fully charge the second battery.
Features:
- Overcomes charging problems of voltage loss due to resistance along cables
- Overcomes charging problems caused by having batteries of different sizes and ages
- Distance between batteries not important- allows second battery to be installed in caravan or trailer
- Ensures second battery is fully charged, reducing battery sulphation and increasing battery life
Maximum charging at 20 amps. Can not overcharge batteries- inbuilt charge controller.

High & Low Voltage Cutout Device
The new ARRID Auxiliary Voltage Controller (AVC) is a small yet powerful device that is used to prevent damage to low voltage appliances (including fridges, halogen globes or televisions) from both high and low voltage. The ARRID AVC will also prevent excessive discharge of batteries, and is available in a higher voltage version for starting batteries (11.8 V DC cutout) or a deep cycle model that allows deeper battery discharge (10.8 V DC cutout). The ARRID AVC will disconnect DC loads when the battery voltage exceeds 16 V DC.
The ARRID AVC has a maximum rating of 25 amps, but will actually cope with higher inductive loads than many similarly rated discharge protection devices.
This is because the ARRID AVC features a 60 second time delay between reaching the designated cut off voltage and disconnecting the load. The AVC will not disconnect the load due to short decreases in voltage caused by the high start-up currents of inductive loads, (eg. compressor refrigerators). This feature eliminates the annoying “chatter” effect that may occur with low voltage cutouts that do not have this feature. Voltages can be adjusted for specific requirements. For further information and specifications contact ARRID.

Smart Relay
The ARRID Smart Relay revolutionizes the way people think about dual battery systems. The Smart Relay combines the best of both worlds, incorporating advanced features in a compact unit. The Smart Relay is suitable for all types of vehicles, making it the ideal battery management solution. The Smart Relay will prevent loads connected to the auxiliary battery from draining the starting battery, and will not allow the auxiliary battery to drain the starting battery when the vehicle starts. Integrating the control unit with the relay makes installing the Smart Relay a breeze!
Features:
- Ease of installation
- Utilizes cold start delay
- Starting battery receives initial charge
- Spike protected
- 12 or 24 volt models available
- Compact design
- LED indicates when circuit is operative
- Flow-over protection
- Isolates starting battery from Auxiliary battery when ignition is switched off

Dual Charge System Controller
The ARRID Dual Charge Electronic is designed to be installed into existing relay or solenoid charging systems. The Dual Charge Electronic will greatly increase the safety of these systems ensuring the starting battery can never be drained by the auxiliary battery during vehicle ignition.
A key feature of the Dual Charge Electronic is the ability to charge two separate auxiliary battery banks using one Dual Charge Electronic. Greater battery capacity gives more power for those heavy loads!
The Dual Charge Electronic is compatible with solar and many other charging systems A durable, no-nonsense control unit, the ARRID Dual Charge Electronic is quality without compromise.

Dual Charge Controller
The ARRID Advanced Charge Controller is the complete package, delivering total battery management. A fully automatic charging system, the Advanced Charge Controller has all the standard functions such as battery isolation and spike protection, but also includes features not normally associated with dual battery controllers. One such feature is the charge control method.
The Advanced Charge Controller operates using an advanced battery voltage sensing system. The Advanced Charge Controller is designed to preferentially charge the main battery until reaching a preset voltage, and only then divert charge to the auxiliary battery. The Advanced Charge Controller ensures you will always be able to start the vehicle.
Another feature is the full function LED display that provides information on operational status. With the added ability to charge a second auxiliary battery the ARRID Advanced Charge Controller is everything you always wanted in a battery management system and so much more!
Models:
BCAACC12V
BCAACC24
Features:
- Will not divert charge to auxiliary battery unless voltage is > 13.7 V DC
- Three LED light display
- Easy to install (installation instructions provided)
- Available in 12 or 24 V DC models.
- The dual battery control unit can be used with 2 relays or solenoids.
