Giant Power Australian-Made Lithium Batteries have a superior 100AMP BMS (Battery Management System). Will charge up to 5x faster than lead-acid batteries. 5-Year Warranty & include an Active Cell Balancer that increases system run-time and efficiency.

What is a 100AMP BMS ?

Unfortunately, our customers are too often burnt by cheap Lithium battery failures exposing themselves and their assets to harm. Most cheaper lithium battery competitors will only have a 50AMP BMS (Battery Managment System), which will not give Aussie customers the ideal battery use capacity. A high-quality BMS system should be rated 100AMP and above, and the BMS is essential to getting a quality lithium battery product and the key to your batteries long-term performance. It's a classic case of paying for what you get; the best quality lithium battery brands are the ones that cost money and have a superior size BMS and Australian Warranty. Many of our customers' applications require Lithium Batteries with higher surge currents.

Upgrade AGM to Lithium Power

Are you thinking of replacing the AGM deep cycle batteries in your camper, RV, caravan or campervan? Then it might be time for a Lithium battery upgrade. Giant Power Lithium Batteries are designed as a true drop in replacment and every cell is protected by an internal 100AMP Battery Management System (BMS), with the control board protecting the batteries from cell imbalance and high voltage situations, giving users a longer battery life. Giant Power batteries are the perfect choice for any application that requires a deep-cycle power supply. This high-quality lithium battery delivers reliable 12V power.


Charging Your Lithium Battery

Giant Lithium Batteries don’t immediately need a special battery charger! Using your AGM battery charger is a temporary solution, not a permanent one. Wherever possible, a lithium battery should be charged using a charger with a lithium profile;  the nominal charge voltage for a 12v AGM battery is 14.1-14.4V, which means that using an AC to DC AGM battery charger that does not have automatic desulfation or equalisation modes and set to use the AGM setting will work correctly. However, it will only get your lithium battery to 95% charged.

We Suggest The Ardent 12V Battery Charger:

Using a 240V AGM charger is a temporary option until you can get a lithium-specific charger . Giant batteries are manufactured with a built-in high-quality 100AMP (BMS) Battery Management System that allows for most charger settings (15A)minimum (except flooded) to be used.

DC-DC Charging For Lithium Batteries

Regarding DC-DC Chargers and solar controllers, you must change these to LiFePO4-specific models, which can charge your Lithium batteries to an entire 100% State of Charge. The advantage of using a LiFePO4 charge profile is that it allows users to get the total capacity out of their lithium battery, as the DC-DC LiFePO4 setting will prolong the battery life. You need a DC-DC charger to effectively manage the power input in a lithium battery. **If you are charging from an alternator, you will need a DC-DC Charger that is designed to manage solar specific to lithium (LiFEPO4).

Reliable Lithium Power

Giant Deep Cycle Batteries feature an internal BMS (Battery Management System) to limit discharge, manage cut-off voltage, and protect the inner battery cells. Giant Lithium Deep Cycle Batteries are the best Australian Made deep cycle batteries. They are perfect for virtually any application where you typically use large lead-acid or AGM batteries for reliable 12V power. The next generation of lithium power storage is here! Giant lithium LiFePO4 batteries weigh less than half of their Lead Acid or AGM counterparts.

They may look reasonably similar to AGM batteries, but internally the Giant Lithium is a different, next-generation concept. Giant lithium deep cycle batteries are made up of prismatic LiFePO4 cells, which are in mass production for many portable devices. The built-in internal battery management system (BMS) within each Giant Battery ensures all the battery cells are uniformly charged and discharged. It provides short circuit, over-current, and reverse polarity protection. This provides you with more protection than a traditional AGM deep-cycle battery.

** Lithium Batteries much like your phone battery are sent in a discharged state - so you must charge before their first use. A new battery has to be completely charged before first use for the optimal battery life and increased performance.

How long do Giant Lithium Batteries last? 

Through extensive cycle testing, we have determined that, after 3,000 complete discharge cycles in extreme conditions, our lithium batteries will have 75%-80% battery life left. The average user not operating their battery in extreme conditions will have 75%-80% battery capacity after 5,000 cycles. Charging and discharging your Giant Batteries every day would last you between 10 and 15 years. With a 5-year pro-rata warranty, our lithium batteries will keep you powered for years. 

LiFePO4 (Lithium Iron Phosphate) batteries solve several problems associated with traditional battery technologies:

  1. Safety: LiFePO4 batteries are considered much safer than other lithium-ion battery chemistries. They have a stable chemistry and are less prone to thermal runaway, which reduces the risk of fire or explosion. This makes them suitable for applications where safety is critical, such as electric vehicles (EVs) and energy storage.

  2. Long Cycle Life: LiFePO4 batteries have a significantly longer cycle life compared to other lithium-ion batteries. They can endure a large number of charge-discharge cycles without significant capacity degradation. This makes them ideal for applications that require frequent cycling, such as electric vehicles, renewable energy storage, and backup power systems.

  3. High Power Density: LiFePO4 batteries offer high power density, enabling them to deliver high levels of power output. They can handle high discharge rates without experiencing a significant voltage drop, making them suitable for applications that require bursts of power, such as electric vehicles and power tools.

  4. Wide Operating Temperature Range: LiFePO4 batteries can operate efficiently in a wide range of temperatures, from extreme cold to high heat. They perform well even in low-temperature conditions, making them suitable for applications in cold climates.

  5. Environmental Friendliness: LiFePO4 batteries are considered more environmentally friendly compared to other battery chemistries. They contain non-toxic materials and do not include heavy metals like lead or cobalt, which are commonly found in other battery types. Additionally, LiFePO4 batteries have a higher energy efficiency, which contributes to reduced greenhouse gas emissions when used in renewable energy storage systems.

  6. Fast Charging Capability: LiFePO4 batteries can be charged at a faster rate compared to other lithium-ion batteries. They can accept a high charging current without compromising safety or cycle life. This feature is particularly beneficial in applications where quick charging is essential, such as electric vehicles and portable electronics.

  7. Maintenance-Free: LiFePO4 batteries do not require regular maintenance, such as electrolyte refilling or memory effect prevention. They have a low self-discharge rate, which means they can retain their charge for longer periods, reducing the need for frequent recharging.

These advantages make LiFePO4 batteries a preferred choice for various applications, including electric vehicles, renewable energy storage, power systems, marine applications, and off-grid power systems, where safety, longevity, high power output, and reliability are crucial factors. Don't miss out on the future of energy storage!

Potable power supply

I bought this an about a month ago, just used at Fraser Island for a week, performed perfectly. I would have given 5 stars but it was advertised with a Bluetooth BMS, this is no longer the case. As reflected on website. A quick phone call answered all my questions so customer service is first rate!

Excellent Product and Service

I bought this box for my wife to use when she camps out in the horse float with the horses. I love it because it's built-in inverter is the biggest available in battery boxes at 1200W (that I could find). It makes it great to use with our multi adjustable induction cooktop the Newave Flex, has plenty of Anderson outlets as well as ciggy sockets and USB. 1 complaint I have is that it has multiple ciggy sockets and only 1 USB socket, in today's day and age should be the other way round. Another suggestion would be for a cable entry point.
