Meet the next generation of reliable off-grid power: our Black Series 100Ah Lithium (LiFePO4) Deep Cycle Battery. 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 (N70 - 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.

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.
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.
