So far so good. This is my first foray into lithium land. Size of slimline batt, fits straight into the space where I had an slimline agm battery. The reduction in weight is also a big plus. I will probably get another one soon. To fill the other space in the rear of wagon.

Fits perfectly into the narrow space in the back of the vehicle. The only small issue is that the caps that cover the terminals are side entry only - that makes the width of the required space so much greater given the large bending radius of the heavy cables. This negates some of the slim line benefits.Our assistant Michelle is very knowledgeable and was a great help.

Bought the battery during the Black Friday sale. Used it for the first time this week. Great product, easily runs the Engle, so far 3 days without recharging and still at 60%. We also have 2x ITech 120 ah lithium Batteries in our van. 6 years and still going strong😊

Preferably battery package print... As Lithium Battery LifePO4 ... Instead of only Lithium Battery, yes, there small printing/wording on the battery itself. Confused customer... that I had to phone 4WD to confirmed it is indeed Li LPO4.

Great product. Very light and size is very compatible with my Triton boat. Will definitely purchase this, or similar, product from 4WD Supercentre again. I fish in National Bass/Bream tournaments and will definitely be offering my opinion on 4WD Supa Centre and Kings products to my fellow competitors.

NEED BIG CAPACITY BUT HAVE LIMITED SPACE? Introducing 12 Volt Direct’s latest release the TVD-LBS100. Designed to fit where other batteries cant, the TVD-LBS100 is the ideal solution to mount behind seats, in canopies or behind draws. This behemoth packs a whopping 100AH of capacity into a slim 50mm chassis and weighs in at only 13KG WHY LITHIUM? Lithium batteries provide far greater useable amp hours than their lead-acid counterparts. Unlike lead-acid lithium batteries can be deeply discharged without affecting the cycle life. This means you can use the battery for longer before having to recharge. In comparison, AGM batteries are generally recommended to only be discharged to 50% of their capacity to maximize their cycle life whereas lithium can generally be discharged to 80-90% of the capacity. COST While the initial investment of a lithium battery is more than lead-acid the service/cycle life of lithium is far superior. Typically lead-acid batteries have a service life of 300-900 cycles whereas Lithium has a cycle life of 2000+ cycles at a much higher discharge. That being said you would expect to replace your lead acid battery 2 or 3 times in comparison to replacing 1 Lithium battery. Longer life Lithium batteries are rated for 2,000 – 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead-acid batteries Powerful Lithium batteries allow you to pull far more amps out of the same size battery systems Light-weight Lithium batteries are less than half the weight of the equivalent lead-acid battery. Fast recharge Lithium batteries charge more efficiently and don’t require as many stages during charging. Therefore, they will charge faster, and hold more of the energy from solar panels and other charging devices. Lithium v AGM Capacities 100Ah Lithium = 160Ah AGM 125Ah Lithium = 200Ah AGM 200Ah Lithium = 320Ah AGM 300Ah Lithium = 480Ah AGM (Based on standard depth of discharge for both Lithium (80%) and AGM (50%). The 12 Volt Direct Difference Deep cycle batteries may appear similar on the outside but don’t be fooled, there are key differences between low-quality offerings often found on online auction sites and 12 Volt Direct’s premium quality offerings. Prismatic Cells The TVD-LBS100 is four high-quality 3.2 volt 100AH prismatic cells connected in series. Prismatic cells provide superior performance than their cheaper cylindrical cell counterparts as they are more stable and shock-resistant. Built-in Battery Management System (BMS) The TVD-LBS100 is equipped with an advanced internal Battery Management System. This monitors and optimizes each Prismatic cell within the battery. It will protect the battery pack from over charge, over discharge, over temperature & short circuit. The BMS helps to ensure safe and accurate operation of the battery. Fits where other batteries cant Suited for custom installations our TVD-LBS100 can fit where others simply can’t. This image shows a custom install behind the rear quarter panel of a 200 Series Toyota Landcruiser. Credit to Authorised Reseller Advanced Installation Service for this awesome install. Built-in Volt Meter The TVD-LBS100 features an LCD screen on the top of the battery to allow you to easily see your battery level of charge at any point in time. The screen is backlit to allow for ease of use whether it’s day or night.
