KickAss 100Ah Essential Lithium Dual Battery Kit

Welcome to the next generation of DCDC vehicle battery charging. KickAss has developed and delivered an onboard vehicle charging solution like no other. Engineered for durability and expertly designed for charging performance, the KickAss DC-DC charger is the new weapon of choice in dual battery systems.

KickAss DC charging at a glance:

The True 4-stage charging features BULK, ABSORPTION, FLOAT and PULSE modes with advanced algorithms enhancing the overall charging performance of auxiliary batteries. This ensures your auxiliary battery is charged the correct way, enabling it to reach maximum charge capacity while also maintaining optimal performance. With a powerful 25 Amp maximum output, it provides fast and effective charging.

This charger overcomes issues caused by smart charging systems and variable voltage alternators in modern vehicles, delivering a consistent output to your auxiliary battery. It ensures reliable charging in both new and older vehicles, helping to maintain and extend battery life.

Inbuilt isolation prevents your auxiliary battery from draining your start battery when the vehicle is off. Smart tech detects charging status automatically, so no manual switching is needed — it's all handled for you from the moment you start your engine.

KickAss DCDC Features

Three Pin Anderson Style Connector
Easily connect your 12V DCDC Charger with the new three-pin Anderson connection, combining positive alternator, negative ground, and ignition wires. Fully compatible with standard two-pin Anderson connectors.

Lithium BMS Sleep Mode Recovery Feature
In Lithium Mode, if the battery drops below safe voltage and enters sleep mode, the charger will initiate recovery mode. It will trickle charge until the cut-in voltage is reached, then resume normal charging. This function helps revive lithium batteries protected by a built-in Battery Management System (BMS).

The charger will display fault codes for open circuit output if the battery is asleep. To attempt recovery, you must select 'LITHIUM' using the 'MODE' button before connecting the charger.

How to wake a lithium battery:

1. Disconnect all loads from the lithium battery.
2. Connect alternator or solar input to the DCDC Charger.
3. Connect the output from the charger to the battery.
4. The charger will flash all battery types; BULK and PULSE LEDs stay lit for 30 seconds before Recovery Mode starts.
5. When the source (e.g. Solar) is active and LITHIUM flashes, recovery is in progress.
6. Once voltage recovers, the charger resumes normal operation and loads can be reconnected.

Maximum Solar Gains with Integrated MPPT
Charge your auxiliary battery from solar using the integrated MPPT solar controller. Ideal for caravans and campers, it ensures efficient solar charging even without the vehicle running.

Plug & Play by Design
Quick installation with Plug & Play Anderson-style connectors — even faster when used with a KickAss wiring kit or battery box.

Crisp LED Display and Control
Bright, easy-to-read LED indicators show charging status and mode. Set battery type easily with the soft-touch MODE button.

Multi Battery Type Compatibility
Compatible with GEL, AGM, WET, CALCIUM, and LITHIUM (LiFePO4) batteries for flexible dual battery setups.

Ultra Compatible
Works with 24V systems for charging 12V batteries, and supports smart alternators with a dedicated voltage sense wire.

Fully Sealed, IP67
Built tough with full water and dust sealing to IP67. Internals are coated for extreme durability against corrosion and moisture.

The Best Protection, Ever!
Includes built-in safety features:

• Short Circuit Protection
• Reverse Polarity Protection
• Over Voltage Protection
• Over Temperature Protection
• Temperature Compensation

KickAss Premium Plug & Play DC-DC Wiring Kit

Introducing the ultimate dual battery system wiring kit, now featuring a three-pin 50 Amp Anderson-style connector with ignition wire. The team at KickAss has carefully developed this premium plug-and-play wiring kit for ultra-easy DIY installations. It’s packed with high-quality components to ensure your setup is smooth and professional.

The kit is fully plug-and-play for any system using Anderson connectors for charging input and includes everything needed for a professional wiring installation. It now comes with our famous Maxifuse cable pre-installed into 6 metres of heavy-duty 8 B&S cable, providing 50A of circuit protection. The new three-pin Anderson plug allows for easier installation by integrating an ignition wire directly into the connector—eliminating the need to run multiple cables through your vehicle.

The cable is pre-crimped with Anderson connector terminals, making it simple to feed through holes and grommets. Once installed, you just clip on the three-pin Anderson connector. The kit also includes cable ties for securing cables, a spare 80A Maxifuse, a 3-metre ignition tail wire, and spare Anderson terminals.

Backwards Compatibility

The three-pin Anderson connector is backwards compatible, allowing a two-pin Anderson connection to work even if the ignition wire is not connected.

The KickAss Premium DC-DC wiring kit is specifically designed for our DC-DC chargers and is not compatible with VSRs.

For Other Installations, Please Use Our Dual Battery Wiring Kit When:

• Wiring to a battery system in the cargo area of the vehicle
• Installing VSRs – see our KAVSRAND kit fully compatible with this setup
• Connecting KickAss battery boxes and power packs
• Connecting auxiliary batteries – using KickAss Maxifuse Cable and optional VSR

This Kit Includes:

• 6 x 50 Amp Anderson terminals
• 1 x 50 Amp 3-Pin Anderson connector
• 1 x 80Amp spare Maxifuse
• 10 x Black cable ties (300mm)
• 1 x 3m tail ignition cable

KickAss Features:

• Bluetooth Mobile App
• Remote Display Screen (optional)
• Parallel & Series Configuration
• 100A Continuous Discharge
• Intelligent BMS
• A-Grade LiFePO4 Battery Chemistry
• Lightweight
• Substantial Useable Capacity
• Certification

Bluetooth Mobile App

Easily monitor your system with your smartphone. The convenient Bluetooth app displays data from your 100Ah battery, including Voltage, Current, State of Charge, Temperature, and other useful information provided by the BMS. If you need even more power, up to four batteries can be connected in series or parallel to boost your output. The Bluetooth app will then connect with each battery simultaneously and provide data on the entire battery bank as a single unit, without the need for an external shunt.

Remote Display Screen (optional)

Enhance your lithium battery setup with our optional LED remote display screen. This convenient add-on allows you to monitor your battery’s performance in hard-to-reach installations, or in high-use areas like your camp kitchen. If you have connected multiple batteries in series or parallel via a data cable, the RDU will show the combined information of the entire battery bank without the need for an external shunt. Data displayed includes SOC, current, time to full charge, and time to empty for the entire bank. Eliminate guesswork and stay on top of your power usage more easily.

Parallel & Series Configuration

The 100Ah lithium battery can be connected to other batteries in series or parallel to create a more powerful battery bank. Configure up to 48V systems in series or 400Ah systems in parallel. This flexibility allows you to build the power system you need, whether you're running high-power inverters or expanding your off-grid setup.

100A Continuous Discharge With 200A Pulse Discharge

The 100A discharge BMS provides ample power to run multiple devices simultaneously, and the 200A pulse discharge makes this battery ideal for inverters that require a high charge capacity. For increased discharge rates, connect multiple batteries in parallel – achieve 200A with 2 batteries (2000W inverter), 300A with 3 batteries (3000W inverter), and so on.

Intelligent BMS

The cutting-edge BMS features 11 layers of hardware and software protection to ensure safe battery operation at all times.
