Next-generation portable power.

NOTE: 3 year warranty applies to batteries supplied from November 2021 onwards. Our previous model came with a 2 year warranty.

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 70% of usable capacity and 99% in an emergency (vs 50%/70% for SLA)
  • Light weight: About half the weight of an equivalent SLA battery
  • Environmentally friendly: Non-toxic, contains no acid, can be installed in any direction

Don’t be fooled – deep cycle batteries might look similar on the outside, but the key differences between low-quality and high-quality batteries can be found on the inside.

Our batteries are constructed from superior grade components, including the cells, battery management system and even the wiring. Not only does this mean your battery will last longer and provide much greater reliability, but it also provides two other significant advantages.

First, our maximum discharge rate is 100Ah for 40 minutes or 150Ah for 2 minutes. This is significantly higher than most others, and is especially important if you plan to use this battery in conjunction with an inverter.

Second, you can connect up to four of these batteries in parallel or up to four in series. This means you can create up to a 400Ah 12V setup, or a 100Ah 48V setup!

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
  • UL 1642: Performance/quality testing to guard against risk of fire or explosion
  • IEC 62133-2:2017: Safety testing of portable lithium batteries under intended use and reasonably foreseeable misuse (including vibration test)
  • IEC 62619:2017: Safety testing of lithium batteries for industrial use
  • CE: The batteries meet EU safety, health and environmental protection requirements

In addition, our manufacturing facility has been certified in accordance with the following international standards:

  • ISO 9001: Ensures quality management systems have been implemented
  • ISO 14001: Ensures environmental management systems have been implemented

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.

LCD digital display

All of our deep cycle lithium batteries now come with a handy LCD digital display on the top of the unit.

This display allows you to easily view your battery’s voltage at any point in time. The screen is backlit, so you can read its output regardless of whether it is day or night.

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 120Ah battery might only be able to deliver 105Ah or even less.

We value our good reputation and will always quote the C20 rating 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.

* Note on discharge current: if you connect multiple batteries in parallel, the maximum discharge current is multiplied by the number of batteries in the array. For example, if you connect two of these batteries in parallel you can discharge at 200A for 40 minutes.
