    Power on the go

    Does everything described on the Box extremely well. Spent a week on Fraiser Island and the battery never dropped no 80%. It was running my 55L duel zone fridge and camp lights.

    Came with a wiring kit was extremely easy to install in the probably 150. I got he the 6m kit which need extending by 1.5meters.

    Would have been nice to be able to select the bigger DCDC changers but the kits still charged up extremely quickly when driving.

    Great product!

    So far very impressed with the all in one lithium battery box. I would rate it 5 stars if the manager at the Acacia Ridge store would’ve given me a free cap with the big purchase.

Frequently Asked Questions

How much power can the KickAss Smart 125Ah Lithium Battery Box deliver and how quickly can it charge?
The KickAss Smart 125Ah Lithium Battery Box has a rated capacity of 1600Wh with a maximum continuous discharge current of 120A and a 25A DC-DC charger for fast charging. It supports charging from 12V or 24V alternators and solar inputs with MPPT technology.
This means you can power high-demand 12V devices reliably and recharge efficiently while on the move or from solar panels. The integrated 25A DC-DC charger ensures your battery gets a quick, optimised charge from your vehicle’s alternator or solar array, keeping your off-grid setup running smoothly.
Can I use this battery box with my existing 24V solar system or alternator?
Yes, the KickAss Smart 125Ah Lithium Battery Box is compatible with both 12V and 24V input systems, including alternators and solar panels, with an input voltage range of 9-32V DC.
This flexibility means it fits seamlessly into a variety of vehicle and solar configurations, including dual battery systems and mild hybrids. The built-in MPPT DC-DC charger optimises charging from your solar panels or alternator, maximising energy harvest and battery life.
How do I set up and monitor the battery box once installed?
Setup involves securely mounting the battery box, connecting your power sources via the Anderson sockets, and closing the lid tightly. The integrated LCD display shows real-time battery voltage, current, state of charge, temperature, and time to full or empty.
For enhanced monitoring, the battery box connects via Bluetooth to the KA Lithium & KA Charge App, allowing you to track performance and configure the DC-DC charger remotely. This smart connectivity ensures you always know your battery status and can optimise charging settings for your adventure.
What safety features are built into the KickAss Smart 125Ah Lithium Battery Box?
The battery box includes a built-in Battery Management System (BMS) that limits maximum discharge and charge currents (120A discharge, 25A charge) to protect the battery. It also features auto-reset circuit breakers on output ports and a secure, impact-resistant casing.
These safety measures prevent overload, short circuits, and physical damage, ensuring reliable and safe operation in rugged off-road and camping environments. The lid must remain closed during use to maintain protection, and the design keeps moisture and dust out, enhancing durability.
How portable is the KickAss Smart 125Ah Lithium Battery Box for off-grid adventures?
The battery box weighs 18.15kg and measures 430mm (L) x 260mm (W) x 398mm (H), making it a compact and manageable power solution for 4WDs, campers, and trailers.
Its reinforced handles and rugged casing make it easy to carry and install while withstanding vibration and dust on the trail. This balance of capacity and portability means you get substantial power storage without excessive bulk or weight.
What types of devices can I charge directly from the battery box?
The battery box includes 2 × USB-C ports with 45W Power Delivery, 2 × USB-A QC3.0 ports with 18W, a cigarette lighter socket (shared 15A), and multiple Anderson connectors rated up to 50A or 120A max for high-power devices.
This versatile output selection allows you to charge phones, tablets, laptops, cameras, 12V fridges, lighting, and even run larger 12V appliances. The fast USB ports ensure quick charging for your essential devices while the high-current Anderson sockets support heavier loads.
How does the battery box protect against environmental factors like water, dust, and heat?
The battery box features a rugged, impact-resistant casing designed to withstand dust, vibration, and off-road conditions. It must be kept away from water and moisture, and the lid remains closed during use to protect internal components.
Operating temperature ranges from 0°C to 55°C for charging and -20°C to 60°C for discharging, ensuring reliable performance in a wide variety of climates. These design choices provide durable, safe power wherever your adventures take you.
Can I use the KickAss battery box to jumpstart my vehicle if the battery is flat?
No, the KickAss Smart 125Ah Lithium Battery Box is not designed for jumpstarting vehicles and should never be used for that purpose.
Instead, it excels as a dedicated off-grid power station with integrated charging and power distribution for your 12V devices. Its specialised design focuses on deep-cycle power delivery and safe, efficient charging rather than high current bursts needed for jumpstarting.
