Description
The KickAss 125Ah Lithium Battery Box Power Station is a fully integrated, all-in-one power hub designed to simplify your entire off-grid setup. With integrated battery storage, alternator charging, solar charging and DC power distribution built into a single compact unit, it eliminates messy wiring, reduces installation time, and delivers a cleaner, more reliable system for touring, camping and remote travel.
All-in-One 12V Power
Instead of piecing together multiple components, this Battery Box Power Station brings everything into one streamlined package. Battery management, charging inputs and power outputs are all housed in the same durable enclosure, giving you a neat, plug-and-play upgrade for any canopy, camper, tub or RV.
Fast 25A DCDC Charging with MPPT Solar
The built-in 25A DCDC charger draws clean, regulated power from your alternator, while the onboard MPPT controller extracts maximum performance from unregulated solar panels. A dedicated solar Anderson input and a triple-Anderson alternator input give you flexible, reliable charging from multiple sources.
DCDC Charger with Supporting Bluetooth App
The DCDC Charger has a dedicated supporting Bluetooth app, which allows you to configure and monitor the DCDC Charger, alternator and solar input, as well as battery charger current.
Integrated LCD Battery Monitor
A bright, easy-to-read LCD screen shows real-time voltage, current, state of charge, estimated run time, charge time, and which inputs are active. You can check the health of your system with a quick glance.
Bluetooth App Control
An additional KickAss app lets you monitor battery performance, receive system alerts, and adjust charging parameters – all from the convenience of your smartphone.
Premium 125Ah Lithium Power
Built with A-grade prismatic LiFePO₄ cells, the Battery Box Power Station offers exceptional deep-cycle performance, long lifespan and superior safety. Rated for over 4000 cycles at 80% depth of discharge, it provides dependable power for fridges, lights, inverters and other essential gear without adding unnecessary weight to your vehicle.
High Output for Serious Gear
This Battery Box Power Station keeps your setup performing smoothly, even under heavy load. A 120A continuous discharge pared with the high power Anderson output means you can confidently run demanding appliances like 1200W inverters, air compressors, fridges and camp accessories simultaneously.
Compatible with 12V & 24V Alternators
Designed to work with both 12V and 24V alternators, it suits everything from family 4WDs to trucks and motorhomes. The adjustable max input current also makes it suitable for hybrids and vehicles with low-output alternators, helping you protect sensitive charging systems.
Adjustable Input Current – Ideal for Hybrids
The DCDC Charger allows you to dial back the alternator input current, making it perfectly suited toy hybrids and vehicles equipped with lower-output alternators.
USB Fast Charging for Modern Devices
