Invicta Lithium Batteries

Developed using over 25 years of industry knowledge and experience

Invicta lithium batteries are available in over 20 12V, 24V and 36V sizes that consist of aluminum encased prismatic cells which have been bolted together using solid busbar connectors. These have been further reinforced with a strengthening frame to resist damaging vibrations.

Invicta lithium batteries are designed to the highest specifications to deliver a premium solution that has been proven to perform. Consisting of high-grade aluminium Lithium Iron Phosphate (LiFePO4) prismatic cells, solid busbar connectors and an integrated BMS, Invicta lithium batteries are a reliable and robust deep-cycle battery for those that need complete confidence in their system.

Our integrated BMS has been engineered for the Australian market and is a robust component that provides automated protection against overcharge/discharge, temperature, short circuit, which can be monitored with Bluetooth models.

All Invicta Lithium batteries have undergone IEC62133/UL1642 certification on a cell level with selected models also achieving IEC62619 on the entire battery and BMS. This testing guarantees the performance and safety of the cells and battery in high-stress environments.

Invicta is available with a market-leading 7-year full replacement warranty. This is due to Invicta's excellent results during independent testing where the Invicta battery easily exceeded over 2000 cycles at 98% DoD during a period of 1000 continuous days of operation while under Australian conditions.

Invicta uses aluminium encased LiFePO4 prismatic cells that are bolted together using a solid busbar for construction. A strengthening frame is also utilised to reduce movement and vibration often associated with off-road vehicles and marine applications.

Invicta's integrated BMS has been securely fitted to the battery, this critical component automatically protects the battery from overcharge/discharge, temperature and short circuit. As an added feature it has passed IEC certification and includes Bluetooth monitoring (BT models only).

The Invicta Bluetooth range allows users to conveniently monitor their battery from their Apple or Android device. Users can easily see live data which includes volts, remaining capacity, current draw and status of the Battery Management System (BMS). This represents a far more accurate and easier way to monitor the battery than conventional means.

Invicta lithium represents a far superior replacement compared to AGM alternatives. It provides the user with a significant weight reduction, can be recharged five times faster, has more efficient use of capacity, can sit unused for up to 12 months and has twice the runtime. Over the long-term, Invicta is also cheaper option.

Manufactured to the highest possible standards

Invicta lithium batteries have achieved two levels of IEC certification. This includes IEC62619 on selected models and IEC 62133/UL 1642 on the entire range.

IEC 62619 certification is an independent test that examines the safety and performance of an entire lithium battery, all of its cells and BMS. The certification process includes a rigorous schedule that ensures the battery will not internally short circuit or propagate, and that it can withstand high impact events, thermal abuse (extreme heat and cold) and over-charge or over-discharge situations. The certification also includes a factory audit undertaken annually to ensure components and processes continue to apply to the highest quality standards.

IEC 62133/UL 1642 certification, which is available on the entire range, is similar to IEC 62619 but at a cell level. At an absolute minimum, a battery should have this level of certification. This guarantees the safety and overall performance of the cells. Many batteries don’t have any certification or irrelevant certifications which is why you should check claimed certifications.

Unlike some other cheap batteries that use a separately sourced Battery Management Systems (BMS), the Invicta range is an integrated component bolted to the battery and developed in the same factory as our cells. Engineered to meet the needs of the Australian market, it allows a high-discharge rate, and is a critical component of the battery that automatically protects the battery from over-charge/discharge, temperature and short circuit. Bluetooth monitoring options are also available, and our 12V200Ah and 12V300Ah batteries are specially designed to overcome inverter start-up issues experienced on larger inverters.

Our batteries include the same BMS on batteries that have been tested to IEC 62619 standards and therefore have undergone the same stringent testing as the rest of the battery to ensure they are of the highest quality.

The Bluetooth feature is available on any battery in the Invicta range that ends in BT and all Invicta Hybrid Starter batteries. It allows the user to conveniently monitor critical information about the battery, which includes charge, discharge, capacity, temperature, voltage and BMS safety features. All via a free application which can be downloaded on any Apple or Android device. This can be especially useful as conventional testing can be difficult and inaccurate. It can also help if the battery has been placed in a hard to reach spot, like behind the seat or battery box, as monitoring can be achieved from 5 meters away. The Invicta Bluetooth cannot be put in series, and for this reason, we have made available a 24V and 36V option to ensure you have access to a solution that will be suitable. There are separate apps for both Invicta Lithium and Invicta Hybrid, this due to the different chemistry, performance and features available on each battery.

We are so confident in Invicta lithium batteries that a 7-year full replacement warranty is now available in approved applications. This is backed by SPB, a company with over 25 years in the energy storage industry.

We can offer this level of warranty because we have had Invicta lithium batteries independently tested and it performed above and beyond the expectations of our technical team. Invicta’s testing easily completed 2000+ cycles at 98% DoD over 1000 days of operation while being subjected to Australian conditions where there were significant temperature variations.

When combined with our IEC Certification and robust construction, our customers can be confident they can do what they do, time and time again knowing they have 2000+ genuine cycles.

Most lithium batteries do conduct testing, but it is not to the extent and level of Invicta’s. It is usually held in a controlled environment, and only to the first 500 cycles. They then project the remaining cycles and performance based on simulations. Further to this, the cycle life tests undertaken in the factory are normally only performed on the cells and not the battery as a whole.

What our customers say

“Extremely happy with my INVICTA lithium battery and the customer service I received from their technical team. INVICTA is the powerhouse of my expedition vehicle and has been in continuous use for over a year now – powering two fridge freezers, lighting, cookers and even a 12-volt air conditioner. The INVICTA app is an excellent addition and keeps me informed of the systems status via my smartphone. Highly recommend!”

“Here at Bathurst Batteries, we don’t just sell Invicta Lithium. We use them in our own camping setups, with confidence! You can tell straight away that a lot of thought has gone into the product and our customers always leave knowing that they have got a top-performing battery that is of the highest quality and construction that will last for years to come.”

Michael Harper

Owner at Bathurst Batteries | New South Wales

“For over 12 months, I have been running Invicta primarily as an electric trolling motor in my boats, and I couldn’t be happier. With trips often going for a week at a time I’ve found that my 100Ah battery will usually last the entire trip without needing a charge, which is excellent, especially when I am travelling light for camping. The Bluetooth monitoring allows me to keep an eye on the capacity, giving me greater confidence while on the water.”
