The most convenient way to monitor your deep-cycle batteries.

BLUETOOTH MONITORING VIA PHONE APP

FULL-COLOUR LCD DISPLAY

PRECISION 100V/500A SHUNT

SUITS 10-120V BATTERY BANKS

DIY INSTALL

This battery monitor, also known as a coulometer, displays essential battery information through its full-colour LCD screen or by connecting your smartphone via Bluetooth. By using a 500A shunt, highly accurate data is collected such as charge level (Ah and %), live current draw (A), live voltage (V) and live watts (W). The monitor also includes an integrated alarm function to alert you when your battery is discharged to a set level, and short circuit and reverse polarity protection technology.

It is suitable for all common battery types including Lithium, AGM, Wet, Gel and Calcium.

Bluetooth® monitoring app

Using our free Bluetooth app, you can easily access all of the information from the battery monitor screen via your smartphone. You can also change settings from the app and wirelessly synchronise them with the monitor.

Create your own portable power station.

5 X ANDERSON PLUG INPUTS/OUTPUTS

2 X USB OUTPUTS (USB-A)

2 X CIGARETTE OUTPUTS

UL 94V-0 COMPLIANT ABS PLASTIC

LARGE DIGITAL DISPLAY

Our heavy duty battery box allows you to turn a regular deep-cycle battery into a convenient portable power station, or create a simple dual battery setup using either a DC-DC charger or our optional 50A Voltage-Sensitive Relay (VSR) and Dual Battery Wiring Kit. It is suitable for a range of battery types including AGM, Lithium, Wet, Gel and Calcium, and can handle batteries up to 330mm (l) x 180mm (w) x 240mm (h) in size.

Constructed of durable ABS plastic and meeting the UL 94V-0 standard for flammability of plastic products, this battery box is a high-quality unit that will last for many years. It contains two 12v outlets with 10A fuses, a dual USB (2x USB-A) outlet, four 50A Anderson-style outlets that can be used as outputs or inputs, and a 175A Anderson-style outlet which can be used as a jump-starter. Unlike most other models on the market, all Anderson-style ports are recessed into the body to minimise the possibility of damage, and the internal cabling uses heavy-gauge wire and quality connectors.

The battery can be charged from a range of sources (including solar panels) by simply plugging into one of the 50A Anderson-style ports. The battery’s charge status and voltage can be easily seen via the large digital display.

Key features

• Constructed from UL 94V-0 compliant fire-resistant ABS plastic
• Multiple port types allows you to connect a range of devices
• Easily connect a DC/DC charger or solar panel to charge the battery, or use the optional 50A Voltage-Sensitive Relay (VSR) and Dual Battery Wiring Kit to charge directly from crank battery
• Can be used to jump start vehicles using our optional 175A Anderson jumper cable set
• All ports are recessed into the body to reduce likelihood of damage
• Easily see battery status with large digital display

Easy dual battery setup

Using a battery box combined with a VSR is the easiest way to create a dual battery setup in your vehicle.

The VSR acts as an isolator, allowing the auxiliary battery (inside the box) to charge directly from the crank battery while the car is running. When the ignition is switched off and battery voltage drops below 12.7V, the VSR automatically cuts the link between the auxiliary and crank batteries.

Using a Hardkorr battery box with voltage-sensitive relay (VSR) is the simplest way to create a dual battery setup in your vehicle.

The VSR acts as an isolator, allowing the auxiliary battery (inside the box) to charge directly from the crank battery while the alternator is producing at least 13.2V (i.e. the engine is running). When the ignition is switched off and battery voltage drops below 12.7V, the VSR automatically cuts the link between the auxiliary and crank batteries to prevent the crank battery from being discharged.

Our optional dual battery wiring kit makes it an easy DIY job to install your dual battery setup.

This Voltage-Sensitive Relay can also be used in 12v setups without a Hardkorr battery box.

PLEASE NOTE: this product is not suitable for vehicles with a variable-voltage alternator OR Lithium Batteries. Please check with your vehicle manufacturer prior to purchase if you think your vehicle may be equipped with a variable voltage alternator.

This plug-and-play dual battery wiring kit makes it easy to turn your Hardkorr Heavy Duty Battery Box into a dual battery setup. It is designed to work in conjunction with our Voltage-Sensitive Relay, or can be adapted to work with a DC-DC charger as well.

This kit contains everything you need to wire up your dual battery setup (other than the VSR/DC-DC charger), including 6 metres of high-quality 8AWG cable and a 50A maxifuse.

Jump starting a vehicle is easy, using the Hardkorr Heavy Duty Battery Box combined with these 175A jump start leads.

Simply insert the 175A Anderson plug into the outlet on the side of the Hardkorr battery box, connect the battery clamps to the terminals on your battery, switch on the ignition and let the battery box do the rest. You’ll never get stuck with a flat battery again!

Accurately monitor the condition of your batteries.

This remote battery capacity monitor, also known as a coulometer, uses a 500A shunt (350A continuous) to return highly accurate readings of battery voltage, live current draw (A) and charge level (Ah and %).

It includes a memory function, and is suitable for all common battery types including AGM, wet, gel, calcium and lithium.
