Unmatched Reliability and Performance: 200Ah Lithium (LiFePO4) Deep-Cycle Batteries

The latest 200Ah lithium deep-cycle batteries are engineered to be the most reliable and long-lasting batteries ever manufactured. With outstanding performance characteristics and full international certification, these batteries ensure you’ll never be caught short of 12V power on your 4WD and camping adventures.

Advanced Manufacturing and Rigorous Quality Assurance

These batteries are produced using top-tier robotic manufacturing processes, ensuring consistent quality with rigorous quality assurance, including serialized tracking and pre-shipment cycle testing. Each battery’s test report is stored for future reference, allowing for unparalleled confidence in their reliability. Backed by a 5-year Australian warranty, these batteries are built to last.

Top-Quality Cylindrical Cells

Constructed with high-quality 26700 high-discharge cylindrical cells, the 200Ah deep-cycle lithium batteries offer superior performance. The cells are carefully matched to ensure minimal internal resistance and voltage differences, and are ultrasonically welded using automated equipment to create strong, reliable connections. Encased in custom-molded ABS plastic cell holders, these batteries are designed to withstand shock and vibration, ensuring consistent reliability.

Cylindrical vs. Prismatic Cells

While prismatic cells are lighter and easier to manufacture, cylindrical cells offer greater efficiency, produce less heat, and tend to be more reliable. These benefits led to the decision to use cylindrical cells, similar to the approach taken by Tesla and Rivian, for these batteries.

Certified to International Standards

These lithium batteries meet all required and optional international standards for performance and safety, including:

• UN 38.3: Safety testing for lithium metal/lithium-ion batteries in transport.
• IEC 62133-2:2017: Safety testing for portable lithium batteries under intended use and misuse, including vibration testing.
• IEC 62619:2022: Safety standards for lithium batteries in industrial use.
• CE: Compliance with EU safety, health, and environmental protection requirements.

The manufacturing facility is also certified to:

• ISO 9001: Quality management systems.
• ISO 14001: Environmental management systems.

More Usable Power, Longer Life

Understanding the difference between nominal and C20 capacity is crucial when comparing batteries. The C20 rating represents the number of amps a battery can deliver over 20 hours, providing a realistic measure of performance. Hardkorr values transparency and always quotes the C20 rating, ensuring you receive the accurate and reliable power you expect.

Why Upgrade to Lithium?

• Long Cycle Life: Lasts up to 10x longer than Sealed Lead Acid (SLA) batteries.
• More Usable Capacity: Safely use up to 80% of capacity, and 99% in emergencies (versus 50%/70% for SLA).
• Fast Charging: Charges up to four times faster than equivalent AGM batteries.
• Lightweight: Approximately half the weight of equivalent SLA batteries.
• Environmentally Friendly: Non-toxic, acid-free, and can be installed in any orientation.

Convenient Remote Reset Switch

The Battery Management System (BMS) in these lithium batteries includes a protection circuit that activates if the voltage drops below 10.0V, putting the battery into 'sleep' mode. Resetting this circuit used to be a challenge, but the included remote reset switch provides an easy solution. Simply connect the switch to the socket on the battery and hold the button for 5 seconds to reset the over-discharge circuit. The switch can also be flush-mounted into your 12V setup for added convenience.

Note on Discharge Current: If multiple batteries are connected in parallel, the maximum discharge current is multiplied by the number of batteries in the array. For example, connecting two of these batteries in parallel allows for a discharge of up to 400A.

Sleep Mode: The 200Ah Lithium Batteries come out of the box in sleep mode to preserve battery life. To wake the battery, simply connect a charge current or use the reset switch, then hold the button down for 5 seconds. Sleep mode will automatically activate after 30 days of inactivity.
