Small in size but big on features!
Ask any full-time tourer to tell you about some of the biggest challenges while travelling the country and you’ll likely find their answer has something to do with 12V power and space. Our 210Ah Slimline Lithium Batteries look to solve both these problems.
Built into a narrow 50mm heavy-duty aluminium case, the batteries are ideally suited to being mounted behind the rear seats in a 4×4 cab, or up on the wall of a canopy, allowing you plenty of extra space to pack the rest of your gear. The batteries can be mounted in any orientation and come with eight brackets, giving you plenty of flexibility in how you decide to mount the unit.
Engineered using high-quality aluminium-encased prismatic cells, our 210Ah battery weighs just 25kg and has excellent vibration resistance qualities making it ideal for those looking to set out on a cross-country trip. The battery has a full 210Ah of usable power – ideal for running 12V fridges, lighting, and pumps – but also has the capacity to run even larger items.
Equipped with an advanced internal Battery Management System (BMS), the battery is capable of discharging at 250A continuous which means that it’s able to run up to 2500W from an inverter. This enables the battery to run, through an inverter, your favourite 240V appliances like coffee machines, toasters, and induction cooktops, without skipping a beat – a feat that hasn’t previously been possible with batteries at this size. Additionally, the BMS allows the batteries to be able to be either linked in parallel or series with up to four other batteries to create larger battery banks of up to 840Ah or systems at up to 48V.
The batteries are certified in accordance with some of the country’s most stringent safety and performance standards, have been fully tested and certified by an internationally renowned lab, and are backed by a comprehensive 5-year warranty.
Our lithium batteries have been certified as meeting all required and optional international standards for performance and safety, including:
- UN 38.3: Safety testing of lithium metal / lithium ion batteries in transport
- IEC 62133-2:2017: Safety testing of portable lithium batteries under intended use and reasonably foreseeable misuse (including vibration test)
- IEC 62619:2022: Safety testing of lithium batteries for industrial use
- ISO 9001: Ensures quality management systems have been implemented
- ISO 14001: Ensures environmental management systems have been implemented
Bluetooth® monitoring app
This battery give you the capability to easily monitor its key data wirelessly, via Bluetooth® connection. You can access this feature by downloading the Hardkorr Battery app which is available for iOS® and Android® devices. With the app you can view:
The app also records a log of any instances where a BMS protection circuit is activated, including over-charge, over-discharge, under-voltage, over-current and over-temperature. You can find it by pressing the shield icon in the top-right corner of any screen.

More usable power, longer life
When comparing batteries it is vitally important to understand the difference between nominal and C20 capacity. To reduce confusion and help to standardise the measurement of battery capacity, most reputable battery manufacturers will quote the capacity of their battery in amp-hours at C20 (also written as C/20), which means the number of amps the battery can deliver if discharged at a constant rate over a period of 20 hours. Using this standard, a fully-charged battery with a capacity of 100Ah could deliver 5A of current per hour for a period of 20 hours before becoming fully discharged (5A x 20h).
Some disreputable manufacturers, however, will advertise the nominal capacity of their batteries and bury the C20 rating in the fine print. Nominal capacity has no practical application and can be up to 20% higher than the C20 rating, so a battery that is advertised as a 100Ah battery might only be able to deliver 80Ah or even less.
We value our good reputation, and will always quote the C20 rating (or even higher) as the battery’s capacity. This means you can be confident that the power we say our batteries can deliver is not inflated to mislead, create confusion or invite unfair comparisons.
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 usable capacity and 99% in an emergency (vs 50%/70% for SLA)
- Fast charging: charges up to four times faster than an equivalent AGM battery
- Light weight: About half the weight of an equivalent SLA battery
- Environmentally friendly: Non-toxic, contains no acid, can be installed in any direction
Handy remote reset switch
The Battery Management System (BMS) inside all lithium batteries contains a protection circuit which trips if the voltage drops below a certain setpoint. In the case of Hardkorr batteries, it is set at 10.0V. This circuit prevents damage to the battery by putting it into a ‘sleep’ mode until it is reset.
In the past, resetting the battery after the over-discharge protection was activated was not easy. Whilst some battery chargers do contain a “wake-up” function, most people had to resort to applying a constant voltage above 12V across the terminals using jumper leads or home-made wires. This was fraught with danger; damage to appliances or the battery were not uncommon.
Our batteries provide an easy solution to this problem; simply connect our included remote reset switch to the socket on the top face of the battery and hold down the button for 5 seconds, and the over-discharge circuit will reset itself. The button can also be flush-mounted into your 12v setup if desired.
