The KickAss 25A DCDC Charger keeps your 12V auxiliary battery charged from your vehicle or solar panel. With integrated MPPT solar regulation, Bluetooth monitoring and pre-wired Anderson-style connectors, it brings charging and control together in one compact unit.
A practical choice for smaller dual battery setups in 4WDs, camper trailers and touring vehicles, it supports both lithium and lead-acid batteries.
Key Features
- 25A continuous charging: Charge your auxiliary battery with a selectable profile suited to its chemistry.
- Vehicle and solar inputs: Connect to a compatible 12V or 24V vehicle supply or solar panel. Alternator input takes priority when both sources are available.
- Integrated solar MPPT: Built-in solar regulation supports charging when you’re parked away from mains power.
- Bluetooth monitoring and control: View charging data, adjust settings, receive fault alerts and access firmware updates through the app.
- Pre-wired Anderson-style connectors: Simplify connections to compatible wiring on the alternator input, solar input and battery output.
- Smart alternator compatibility: Supports fixed and variable-voltage alternators, with an ignition trigger connection for smart alternator installations.
- Lithium recovery: Automatically initiates recovery for compatible lithium batteries in low-voltage protection mode.
- Adjustable alternator draw: Configure the maximum input current to suit the vehicle’s available supply.
- Starter battery isolation: Stops alternator charging when input voltage falls below the applicable cut-out threshold.
- IP66 protection: Dust-tight construction with protection against powerful water jets.

Compatibility & Installation
Designed to charge a 12V auxiliary battery. The 12V/24V designation refers to the vehicle input, not support for charging a 24V battery bank.
Select the correct battery profile and check that your battery allows the selected charging current. Smart alternators require the ignition wire connection. For hybrid vehicles, confirm the available supply voltage and current before installation.
Pre-wired connectors simplify installation, but suitable vehicle wiring, circuit protection and battery connections are still required. Additional installation components are sold separately. Follow the user manual for mounting, solar connection and wiring requirements.
