Description
Powerful 40A Dual Battery Charging
With a high 40A output, this charger is perfect for keeping larger lithium and lead acid battery systems topped up and ready for action. It ensures fast, safe charging for demanding off-road or touring applications.
Bluetooth Monitoring & App Control
Connect your charger to your smartphone via Bluetooth to monitor performance in real time. The KickAss App gives you complete visibility over charging status, voltages, current flow, and system alerts – all from your pocket.
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.
