Next-generation portable power.
Our 100AH deep-cycle lithium batteries consist of four high quality aluminium-encased prismatic cells connected in series, each with a nominal voltage of 3.2v. Whilst more expensive to manufacture, prismatic cells are much more stable and shock-resistant than cheaper options which simply consist of banks of cylindrical cells wired together.
These batteries use an advanced battery management system (BMS) to ensure an even energy balance between cells and allow the batteries to be connected in parallel or series (up to 4). The BMS contains an intelligent protection circuit module which protects against overcharge, over-discharge, short-circuit and over-temperature.
Our battery cells are protected by custom-molded EVA rubber cushioning. This cushioning offers protection against knocks and drops, and ensures better stability and longevity when the batteries are used in high-shock and high-vibration environments such as marine and vehicle applications.
These batteries have been tested and fully certified as compliant with the requirements of UN/DOT 38.3 standard for lithium cells and batteries.
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
The Hardkorr difference
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!
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.
