• 5000 CYCLES (80% DoD)
• ONLY 9.7KGS
• BLUETOOTH APP

Designed for serious 4WDers, campers and tourers, this battery delivers exceptional performance, durability, and efficiency — ensuring your setup never runs out of 12V power when you need it most. Built to fit seamlessly into standard Group 24 (NS70 - commonly referred to as 10in case) battery trays and boxes, it’s the perfect drop-in replacement for traditional AGM units.

Precision Engineering & Quality You Can Trust

Each Black Series battery is produced using state-of-the-art robotic assembly and verified through a strict quality control process, including serialised tracking and comprehensive pre-shipment cycle testing. Every unit’s test report is archived for reference, and our confidence in quality is backed by a 5-year* Australian warranty.

WHEN SIZE REALLY DOES MATTER

Light and Compact

Weighing just 9.7kg, the Hardkorr 100Ah Lithium LiFePO₄ Black Series battery delivers impressive capacity in an incredibly light and compact package. Compared to traditional AGM or lead-acid batteries of the same size, it’s significantly lighter, making it far easier to handle, transport, and install in your setup. Its compact design also allows it to fit neatly into tight spaces in vehicles, canopies, or camper trailers, helping reduce overall system weight without sacrificing reliable power for your off-grid adventures.

Keep an eye on your battery

Wireless monitoring app

The HK App offers a range of useful features to ensure you have all the information you need at your fingertips:

• State of charge
• Nominal voltage and capacity
• Live current draw and battery voltage
• Status indicators (standby, discharging, charging)
• Time to empty / Time to full
• Total charge cycles
• Temperature monitoring
• Detailed cell information

Connect to multiple batteries, group them in groups (parallel / series/ mixed), received unbalanced group alerts.

Certified for Safety & Performance

Our Black Series lithium batteries meet or exceed all major global standards for safety, quality, and environmental compliance, including:

• UN 38.3 – Transport safety testing for lithium batteries

• UL 1973 – Quality and fire risk prevention

• IEC 62133-2:2017 – Portable battery safety under real-world use

• IEC 62619:2:2022 – Industrial battery safety and reliability

• CE – European compliance for safety, health, and environmental protection

Manufacturing facilities are fully accredited to:

• ISO 9001 – Quality management

• ISO 14001 – Environmental management

True Capacity, Honest Ratings

We quote C5-rated capacity, not inflated nominal figures. This means our 100Ah battery will reliably deliver 20A of current for 5 hours straight — exactly what you expect from a true 100Ah battery. Many cheaper alternatives exaggerate their specs by using nominal ratings, which can be up to 20% higher than real-world performance. With Hardkorr, you get authentic capacity, honest data, and dependable power.

Important Note

This battery is not designed for under-bonnet installation OR cranking purposes.

When connecting multiple batteries in parallel, total discharge current scales with the number of batteries. For example, two batteries can safely deliver up to 200A combined.
