KickAss 12V 300Ah Lithium Complete Dual Battery Kit with 2000W Inverter, 12V Control Hub with 40A DCDC Charger & Wiring Kit

The KickAss Smart 12V 300Ah Ultra-X Lithium Compact Deep Cycle Battery LiFePO4 is the first battery in the second series of our premium Ultra-X range, building on everything customers already love. This second series introduces a new look along with key upgrades including an IP65-rated enclosure, integrated Low Voltage Recovery (LVR) button, and supports AS/NZS 3001.2 compliant installations. It's the next evolution of KickAss Ultra-X Lithium Batteries, delivering the same premium performance with even more capability.

With 300Ah of usable capacity and a 300A continuous discharge, it's built to power demanding off-grid setups, making it the ideal battery to pair with a 3000W inverter for running fridges, induction cooktops, coffee machines, power tools, lighting and other 12V and 240V appliances at the same time. This high-performance 12V lithium battery gives you more power without taking up valuable space.

Its compact form factor opens up installation options that simply aren't possible with many large-capacity batteries. Mount it neatly beneath caravan beds or bench seats, inside ute tubs under roller covers, within canopies or in camper trailers. A built-in vent means that the battery supports AS/NZS 3001 compliant installations, while the rugged metal housing, IP65 rating and intelligent Battery Management System ensure reliable performance in harsh Australian conditions.

Bluetooth monitoring lets you check battery status, capacity, voltage, temperature and current directly from your smartphone, while the optional Remote Display provides the same information for those who prefer a dedicated screen. If you accidentally run your battery too flat, then the integrated Low Voltage Recovery (LVR) button makes it easy to reawaken the BMS after an over-discharge, helping you get back on the road with the touch of a button.

As your power needs grow, your battery system can grow with them. Connect up to four Ultra-X 300Ah lithium batteries in series or parallel to create a powerful battery bank, then monitor the entire system through the KickAss app or Remote Display without needing an external shunt. The KickAss Ultra-X 300Ah LiFePO4 Battery delivers a cleaner, simpler and smarter way to build a scalable off-grid power system.

Take the hassle out of building your dual battery system with the updated KickAss Control Hub, now featuring our new Smart 40A DCDC Charger with integrated Bluetooth. This all-in-one panel brings your key 12V essentials together in one tidy, easy-to-mount unit.

The upgraded Smart 40A DCDC Charger simplifies your setup by eliminating the need for separate charging devices. It delivers reliable charging from both your vehicle’s alternator and solar input, ensuring your auxiliary battery stays topped up whether you’re on the move or off-grid. With Bluetooth capability built in, you can now configure and monitor your charger directly from your mobile device. View real-time voltage, current, charge status and system health, and receive instant alerts or warnings if anything needs attention.

This control hub is built to power up to 15 devices at once, giving you a central point to manage lights, fridges, pumps, inverters and more. The clean front panel layout and simple mounting options make installation straightforward, even in tight canopy builds. Whether you're running a full touring setup or building your first 12V system, this panel keeps everything organised, protected and easy to use.

KickAss 12V to 240V Pure Sine Wave 2000W Inverter Feature Overview

2000W Continuous Output

Plenty of power to run all your AC essentials while on the move—induction cooktops, coffee machines, battery chargers for your power tools, and more.

Pure Sine Waveform

Delivers a clean and reliable sine wave output that replicates the AC signal from a home power point. Unlike modified sine wave inverters, the KickAss Pure Sine Wave Inverter is ideal for running sensitive electronics such as laptops, Starlink systems, and CPAP machines.

AC Automatic Transfer Switch

Simplify your off-grid setup with the integrated Automatic Transfer Switch. Power your AC devices from your battery bank, then seamlessly switch to mains power by plugging in the AC input cable. If mains power drops out, the inverter automatically switches back to battery power without interruption.

Multiple Protective Features

Multi-level safety protection uses both software and hardware safeguards to protect you, your inverter, and your devices. The system continuously monitors operation and automatically enters protection mode if necessary. Integrated Residual Current Devices (RCD) and Circuit Breakers (CB) provide added hardware protection, making it suitable for commercial and domestic use.

Optional Remote Control Display (Not Included in Base Version)

Enhance your setup with the optional remote display, allowing you to monitor and manage power usage remotely. The flush-mountable screen is low-profile and ideal for installation near your camp kitchen. It includes an integrated on/off switch for conserving battery power when the inverter is not in use.

Note: Only compatible with the blue KickAss remote inverter screen.

This 3-pin Anderson-style connector with built-in ignition wire makes connecting your 12V dual battery system easy. Perfect for wiring DC/DC chargers, battery boxes & auxiliary batteries.  

The KickAss Remote Smart Lithium Battery Display Unit is compatible with the KickAss Smart and Ultra-X series batteries. Simple plug-and-play via the RJ45 connector, it allows you to monitor State of Charge (SOC), voltage, real-time current, and temperature of either a single battery or multiple batteries connected in parallel or series. Includes 5m extension cable.

Take full control of your battery system with the KickAss Battery Display Monitor – your window into real-time performance, protection, and peace of mind.

Monitor Your Battery Like a Pro

Never guess your battery’s health again. With a full-colour screen, you can instantly view:

• Battery temperature
• Current draw
• Voltage
• Charge status
• Time to empty/full
• Cell balance and more

Built-In Battery Management System (BMS)

The integrated KickAss BMS keeps your battery safe — actively protecting against:

• Overvoltage and undervoltage
• Short circuits
• Overload
• High temperatures

Stay alerted with smart error messages and stay in control from your display or compatible mobile device.

Easy Flush-Mount Design

Install it where you need it most. Whether it's in your canopy, van, or camper setup, the flush-mount design with included screws and universal hole spacing makes installation fast and secure.

Compact Dimensions

• Display: 126mm (W) x 66.61mm (H) x 23mm (D)
• Cable Length: 440mm
• Mounting holes for quick surface installation

The KickAss Battery Display Monitor isn’t just for looks – it’s your off-grid command centre. Whether you're heading bush or running gear off your canopy, this screen keeps your system protected and your trips worry-free.

KickAss Pure Sine Wave Inverter Remote Display Panel Feature Overview

Real-Time Monitoring

Unexpected power fluctuations can damage your equipment and waste valuable energy. With real-time monitoring, you can track your energy generation and power usage, spotting any problems early. This keeps your setup running smoothly and efficiently at all times.

Remote Control

Monitor and manage your power consumption from a distance—for example, from the front seat while your inverter is installed in the back of your truck. The included 3-metre cable allows you to access and control your inverter system easily.

Fault Diagnostics

When a system malfunction occurs, diagnosing the problem can be challenging and time-consuming. The KickAss Inverter Remote Display automatically identifies and reports inverter faults, providing detailed diagnostics to simplify troubleshooting.

Intuitive User Interface

The display screen is clear and easy to navigate. View energy metrics, adjust settings, and set alerts with confidence—no guesswork, just clear and precise information.

Compatible with Most KickAss Inverters

The remote display unit is compatible with KickAss 2000W and 3000W inverters (not compatible with 700W or 1200W models). Seamlessly integrate it into your current setup or upgrade your system with ease.

Please note: This remote display is not compatible with older red KickAss 700W, 1200W, 2000W, or 3000W inverters.
