    The slimline battery was just what I needed due to the very limited space I had to work with. Installation was easy, basically just plug and play. The remote battery monitor with bluetooth is brilliant. It looks like a rugged piece of equipment and should serve me well. Yet to use it in anger, but it has to be an improvement on my old lead acid setup!

The KickAss Smart Ultra Slimline Lithium Battery offers a rated capacity of 105Ah and an energy output of 1344Wh at a nominal voltage of 12.8V. It supports a maximum continuous discharge current of 100A and a maximum continuous charge current of 50A.
This means you get a reliable and robust power source ideal for extended off-grid use, with enough capacity to run 12V appliances and systems efficiently while maintaining excellent cycle life and battery health.
Can I use this battery with my existing solar setup or 4WD dual battery system?
Yes, the KickAss 12V 105Ah Ultra Slimline Lithium Battery is designed for solar systems, 4WD dual battery setups, caravans, motorhomes, and emergency power systems. It includes 2 x 50A Anderson connectors and 2 x 175A Anderson connectors for versatile compatibility.
This flexibility makes it easy to integrate with your current off-grid or vehicle power systems, ensuring seamless plug & play installation and reliable power delivery for your adventures.
How do I safely set up and start using the KickAss Ultra Slimline Lithium Battery for the first time?
Before first use, fully charge the battery until the charger reaches the "Float" stage, indicating 100% state of charge (SOC), and complete a full charge cycle. This calibrates the battery’s SOC for accurate monitoring and optimal performance.
Following this ensures your battery’s management system works correctly and prolongs battery life. The battery also features Bluetooth compatibility and a Remote Display Unit for easy status monitoring.
What safety features does the battery have to protect it during use?
The battery includes a 100A internal Battery Management System (BMS) that protects against over and under voltage, over and under temperature, overcharge, over-discharge, and short circuits. It also triggers overcurrent protection if the current exceeds 100A.
These built-in safeguards mean your battery operates safely and reliably in harsh conditions, giving you peace of mind on every trip while maximising battery longevity.
Can I connect multiple KickAss Ultra Slimline batteries in parallel or series to increase capacity or voltage?
No, the KickAss Ultra Slimline Lithium Battery is not suitable for parallel or series connection. The internal BMS and design are optimised for single battery use to ensure safety and performance.
However, its 105Ah capacity and 100A discharge rating provide ample power for most off-grid and vehicle applications, making it a strong standalone power source for your needs.
How heavy is the KickAss Ultra Slimline Lithium Battery, and is it easy to install in tight spaces?
The battery weighs 16.5 kilograms and has an ultra-slim form factor designed specifically for fitments where space is limited. Its metal case includes mounting brackets and optional DCDC bracket kits for easy installation.
This slimline design allows you to maximise space in your vehicle or off-grid setup without sacrificing capacity or power, making it ideal for compact or custom installations.
How long can I expect the battery to last in terms of charge cycles?
The KickAss Ultra Slimline Lithium Battery delivers approximately 2000 cycles at 80% depth of discharge (DOD) and up to 4000 cycles at lower discharge rates.
This exceptional cycle life ensures years of dependable power, reducing the need for frequent replacements and providing excellent value for your investment in off-grid energy solutions.
What monitoring options are available to keep track of the battery’s status while in use?
You can monitor the battery’s status via Bluetooth using the KickAss KA App (available on Android and iOS) or through the optional Remote Display Unit (RDU) that plugs directly into the battery.
These tools allow real-time monitoring of battery health, state of charge, and alerts, giving you full control and confidence over your power system during your adventures.
