Features & benefits
- The Largest & Lightest On The Market
This is the biggest and lightest battery box power station on the market, offering 205Ah of premium prismatic lithium, a 40A DCDC with Solar MPPT and a 200A discharge in a surprisingly portable 23.5kg package. - All-in-One 12V Battery Box Power Station
This Battery Box Power Station is an all-in-one unit that combines battery storage, alternator charging, solar charging, and DC power distribution in a single integrated system, removing the need for multiple separate components. With supporting Bluetooth apps that allow you to monitor both the DCDC Charger and your battery, it streamlines installation and reduces clutter. - 40A DCDC Charger with Solar MPPT
The built-in DCDC + MPPT charger delivers fast, efficient charging both when you’re driving (via alternator) and when you’re parked (via solar). A dedicated Anderson input handles unregulated solar panels, while the triple-Anderson alternator input provides reliable charging straight from your vehicle. The DCDC Charger is supported by the KA Charge app, allowing you to monitor and configure the DCDC charger itself, as well as solar input, alternator input, and battery charger current. - Built-In Smart Battery Monitoring via Bluetooth
Enjoy the convenience of monitoring and controlling your battery via the KA Lithium App, which allows you to see battery health and receive alerts directly from your phone. - Integrated LCD Battery Monitor
A built-in LCD screen shows voltage, current, state of charge, estimated time-to-full or empty, and which inputs are active (ie, solar or alternator). It lets you monitor performance at a glance without needing your phone. The onboard LCD display gives you instant access to the key information you need on the road. Voltage, charging and load currents, state of charge, estimated run time, and active charging source indicators are all displayed clearly so you can check system status without reaching for your phone. - 205Ah EVE A-Grade Prismatic Lithium Cells
The Battery Box Power Station is built with premium prismatic LiFePO₄ cells for dependable deep-cycle power, delivering over 4000 cycles at 80% depth of discharge. It’s lightweight, safe, and perfectly suited to off-grid touring, RVs, 4WDs, and camping setups. - High-Current 200A Discharge
Handles demanding appliances like 2000W inverters, coffee machines, air fryers, fridges, compressors and other high-draw equipment. Delivers stable, reliable power so your setup performs at its best, even under heavy load. - Compatible with 12V & 24V Alternators
Designed to work with both 12V and 24V alternators, giving you seamless charging across a wide range of vehicles. - Adjustable Max Input Current – Hybrid Compatible
By allowing you to limit alternator input current, this DCDC charger is suitable for hybrids and vehicles with lower-output alternators. - Integrated USB Fast Charging

This Power Station delivers real plug-and-play convenience, plus integrated tie-down slots and optional battery trays for simple, straightforward installation. - Built Tough
Designed for tough Australian conditions, the unit is built with an impact-resistant shell, reinforced carry handles, and durable internal components. It can handle dust, vibrations, and a tough off-road life. - What’s Included:
1 x 205Ah Lithium Power Station - All-in-One Power System
Instead of juggling separate chargers, panels, displays and distribution gear, this all-in-one Battery Box Power Station integrates battery storage, alternator charging, solar MPPT and output distribution into a single housing. Two supporting Bluetooth apps give you real-time visibility of both your DCDC charger and battery performance, helping you streamline your build and reduce clutter inside your vehicle or canopy. - Fast, Efficient Dual-Source Charging
A built-in 40A DCDC charger with MPPT ensures your battery is always maintained at peak health, whether you’re on the move or parked up at camp. The alternator input uses a triple-Anderson connection for secure, high-current delivery, while a dedicated Anderson solar input allows you to plug in unregulated solar panels without extra regulators or adapters. It’s a dependable charging system designed to maximise every amp. - Bluetooth Smart Control
With integrated Bluetooth connectivity, you can monitor and configure charging behaviour directly from your mobile device. Check battery health and performance, review charging status, receive system alerts and fine-tune your DCDC settings through the KickAss app. It’s a simple way to stay on top of your system. - Premium 205Ah LiFePO4 Battery Power
Inside the unit are A-grade 205Ah prismatic LiFePO4 cells selected for long-term reliability and deep-cycle durability. 4000 cycles at 80% depth of discharge, consistent power delivery and a lighter overall system weight make it ideal for long touring, multi-day camp setups and stable energy storage. - High-Draw Appliance Ready
With a 200A maximum discharge capability, this Battery Box Power Station is built to handle serious loads. Run fridges, compressors, air fryers, coffee machines, power tools or high-draw inverters with confidence. It delivers smooth, reliable output even under demanding conditions. - Compatible with 12V and 24V Alternators
The charger is compatible with both 12V and 24V alternators, making it suitable for a wide range of utes, wagons, trucks and touring setups. Whether you’re upgrading an existing build or moving gear between vehicles, charging remains simple and consistent. - Hybrid-Friendly Charging
If your vehicle has a low-output alternator or hybrid system, you can dial back the input current to suit its limits. This prevents overloading sensitive vehicles while still delivering dependable charging performance. - Fast USB Power for Devices
The unit includes dual USB-A QC3.0 and dual USB-C 45W PD ports, giving you high-speed charging for phones, tablets, drones, cameras, laptops and other USB-C gear. It’s ideal for both work and recreation when you’re away from mains power. - Six Pre-Wired Anderson Ports
With six 50A Anderson input/output ports, the system is ready for immediate use with solar panels, alternator inputs, fridges, lights, compressors or other accessories. No rewiring or complex setup required. - Simple Installation and Flexible Mounting
