KickAss 40A DCDC Complete Dual Battery Kit with Smart Shunt and Wiring

The KickAss Smart Monitor Lite Shunt + Tank Sensor is a powerful, easy-to-use solution for monitoring your off-grid power and water systems. Designed for touring rigs, caravans and 4WD setups, it gives you clear, reliable insight into how your battery bank is performing, how long you can keep running your gear, and when it’s time to recharge or top up the tank.

At the heart of the system is a high-capacity 600A shunt that accurately measures charge and discharge current, battery voltage and State of Charge. This allows you to understand exactly what’s happening inside your battery bank, helping you manage power more efficiently and avoid unexpected shutdowns when running fridges, lighting, inverters and other essential off-grid equipment. As loads and charging sources change, the system continuously provides real-time calculations and updates how long your battery has left to run or how long it will take to recharge. This takes the guesswork out of power management and makes it easier to plan your usage while travelling off-grid.

The Smart Monitor Lite can also connect to your tank sensor or sender, allowing you to monitor both your battery data and water level from a single unit. It’s compatible with resistive and voltage-type tank senders and can be calibrated to suit virtually any tank size or shape.

Monitoring and setup are simple thanks to Bluetooth connectivity and the dedicated mobile app. View real-time voltage, current, power and State of Charge from your smartphone, configure battery and tank settings, and review historical performance data whenever you need it. For quick checks without reaching for your phone, the colour LCD remote display provides clear, at-a-glance system information right where you want it.

Installation and configuration are straightforward, even for more complex setups. The intuitive app interface guides you through setup with clear menus and prompts, making it easy to tailor the system to your specific battery chemistry and capacity. The shunt supports AGM, lithium and other common battery types, from small single-battery systems through to large dual-battery lithium banks.

Integrated data logging records voltage, current and temperature for up to 35 days, allowing you to review power usage trends over the course of a trip. With a wide input voltage range and flexible power options, the unit can be powered directly from the battery or an external supply and used with battery banks of any voltage. For added control and protection, the external relay output allows you to automate system behaviour based on voltage, current, power or temperature.

Simple Plug & Play Installation

Thanks to Anderson-style connectors, installation is quick and hassle-free with no complex wiring required. It’s designed for DIY setups and easy integration into your existing system.

Dual Input: Alternator & Solar Charging

Charge from your vehicle’s alternator while driving or connect a solar panel when stationary – this charger handles both. Its built-in MPPT solar regulator ensures maximum efficiency when using solar input.

Built for Aussie Conditions

Rated IP66, the KickAss 40A DCDC Charger is waterproof, dustproof, and rugged enough to handle corrugated tracks, extreme heat, and remote adventures. It’s built tough for Australian conditions.

Compatible with 12V & 24V Alternators

Highly versatile, this charger is compatible with both 12V and 24V alternators, making it suitable for a wide range of vehicle types including trucks, commercial vehicles, and 4WDs.

Adjustable Max Input Current – Hybrid Compatible

The maximum input current can be configured via the Bluetooth app, allowing the charger to limit the draw from your vehicle’s alternator, without reducing the maximum charge current when charging from solar. This makes it ideal for some hybrid vehicles or those with low-output alternators, helping prevent overload and ensuring stable, efficient charging without placing strain on your electrical system.

Smart Alternator Ready

Modern vehicles with smart alternators are no problem. The unit supports both smart and fixed-voltage alternators and includes an ignition trigger wire to start or stop charging based on engine status.

Lithium Battery Compatible

Fully lithium-ready, this charger includes an automatic lithium wakeup function that can safely restore LiFePO4 batteries from low voltage protection or sleep mode – no manual intervention needed.

Advanced Multi-Stage Charging

Precision charging algorithms help extend the life of your auxiliary battery. The charger delivers multi-stage charging tailored to the battery type, helping maintain peak performance over the long haul.

Starter Battery Isolation

To protect your starting battery, the charger only delivers current to your auxiliary battery when the engine is running, and automatically disconnects when the vehicle is off – eliminating unwanted drain.

Supports Multiple Battery Chemistries

Whether you’re using lithium, AGM, wet, gel, or calcium batteries, this charger has you covered. It’s a versatile solution designed to support a wide range of battery types.

Perfect for 4WDs, caravans, camper trailers, and off-grid touring setups, the KickAss 40A DCDC Charger with Solar MPPT and Bluetooth delivers intelligent charging for serious adventurers.
