KickAss 12V/24V 25A DCDC Charger with Solar MPPT & Pre-Wired Anderson Plug

The KickAss 25A DC-DC Charger is a next-generation onboard charging solution designed to safely and efficiently charge your auxiliary battery directly from your vehicle’s alternator. Built tough for off-road and touring conditions, it delivers reliable multi-stage charging with full lithium compatibility and integrated safety systems.

• 25A DC-DC alternator charging
• 4-stage smart charging (Bulk, Absorption, Float, Pulse)
• Lithium sleep mode recovery
• Integrated MPPT solar input
• 3-pin Anderson plug connection
• Automatic battery isolation

Smart 4-stage charging
The charger uses an advanced 4-stage charging algorithm to ensure your auxiliary battery is charged correctly and efficiently. It continuously adapts output through bulk, absorption, float, and pulse stages to maximise charge capacity while maintaining long-term battery health.

Alternator and solar charging in one unit
Designed for modern vehicle systems, this DC-DC charger stabilises variable alternator outputs and ensures consistent charging to your auxiliary battery. It also includes an integrated MPPT solar input, allowing efficient solar charging when the vehicle is parked or off-grid.

Automatic battery isolation
Built-in isolation technology prevents your auxiliary battery from draining your start battery when the engine is off. The system automatically detects ignition status, removing the need for manual switching or external isolators.

Lithium recovery mode
If a lithium battery enters low-voltage sleep mode, the charger can safely initiate recovery charging. Once the battery reaches cut-in voltage, it automatically resumes normal charging cycles, helping restore protected lithium batteries.

Plug and play Anderson connection
A 3-pin Anderson-style connector simplifies installation by combining alternator positive, ground, and ignition signals into a single connection. It is also compatible with standard Anderson plugs for easy integration into existing setups.

Wide battery compatibility and protection
Supports AGM, Gel, Wet, Calcium, and LiFePO₄ batteries. Built-in protections include short circuit, reverse polarity, over-voltage, over-temperature protection, and temperature compensation for safe operation in harsh environments. The unit is fully sealed to IP67 for dust and water resistance.
