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.
The Hard Korr® 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:
- 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.
- 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!
NEW 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 understand your battery’s charge level and voltage at any point in time. The screen is backlit, so you can read its output regardless of whether it is day or night.

Still early days but i am impressed so far. Been so much lighter than a AGM batterie is pretty damn good.
I ran me dometic 35ltr fidge on -2 n empty for 5 days n 10hrs b4 it ran out. Thats pretty good in my eyes.

I have fitted one of these in my 4WD (in the back) and it is connected to a Redarc BMS30 system. I will typically run a car fridge on a weekend trip and run the fridge as a freezer on a bigger trip where I will also be recharging batteries (including with a 350W power inverter.
It is still early days, but so far the battery has performed well. Running the car fridge as a freezer overnight would draw down between 25 and 35% of the battery capacity. With the Redarc system I have, the battery recharges very quickly (faster than my old duel battery system with an AGM battery of similar capacity). So, with the usable capacity and fast recharge, I don’t have to worry as much as I used to with my old system about running the battery flat.
It is too early to say how long the battery will last, but it appears to be well constructed so I am hopeful that it will be OK on rough roads. I did have to put a thin strip of rubber between the battery clamp and battery to keep the clamp clear of the small LCD display that is on the top panel of the battery. I also opted to buy some battery posts so that the battery electrical connections are via a standard battery clamp (rather than bolt eye terminals to the battery with the supplied M8 bolts.
Overall, I think this is a good usable capacity for the way I use an auxiliary battery, especially for the size and weight of the battery – the low weight of lithium batteries seems incredible if you are used to lead acid or AGM batteries.

A mate and I bought a 100amp lithium battery each to run our wagon fridge and camping accessories and to say we’re impressed is an understatement.
The battery performs well against the claimed rating which after research was one of my biggest concerns when choosing which lithium to buy as the common comments made with lithiums is theyre claimed Ah and actual Ah are often quite different.
We now have no drama running our car fridges for nearly a week with no driving or solar input and charge recovery is awesome.
Sam from Korr was more then helpful with all the questions and saw to it we were happy with our purchases with 0 sales push i might add
I’d highly recommend these batteries to anyone and certainly will be purchasing more for future projects.

I have 2x of these 100Ah batteries in my Car. they run my 2000w inverter with ease. I can highly recommend them as the represent good value to.
Craig Boyd. Renegade Camping Trailers –
These are my first lithium batteries and I love them, heaps of power! and they weigh bugger all. Also change them with my 200w Heay Duty Portable Solar Panel from Korr Lighting it works a treat good gear. It means I can camp for weeks at a time. ?
