Hardkorr’s 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.
The 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

* 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.
