Invicta LiFeP04 12v 50ah slim lithium battery:

Invicta lithium is designed to the highest specifications to deliver a premium solution that has been proven to perform. Consisting of high-grade aluminium LiFePO4 prismatic cells, solid busbar connectors and an integrated BMS, Invicta lithium is a reliable and robust lithium 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.

IEC certification and quality assurance:

 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.

Battery management system (BMS): 

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.

Bluetooth range:

The Bluetooth feature is available on any battery in the Invicta range that ends in BT. 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.

7 year warranty:

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.

Projecta IDC25L:

New from Projecta, the Intelli-Charge IDC25L is the toughest and most advanced dual battery management system available on the market today. Allowing you to charge your 12V second/auxiliary lithium deep cycle battery on the go, the IDC25L is shock, vibration and dust proof. The unit is also water resistant, making it suitable for both in-vehicle and under-bonnet installation.

A truly sophisticated dual battery management system ideal for 4WD and camper trailer applications. Provides an advanced 5 stage charge simultaneously from both solar and alternator inputs.

Able to charge simultaneously from both solar and alternator (9–32V) inputs, IDC25L can also function as an MPPT solar controller and features dual charging modes for compatibility with both smart and conventional alternators. Loaded with a host of safeguard features, the easy to install unit includes over/under voltage, anti-sparking, reverse connection and over temperature protection systems to ensure peace of mind.

The IDC25L sets a new benchmark for DC-DC battery management.


Over Temperature Protection- IDC25L will automatically adjust its output based on battery temperature, preventing overcharge and overheating in small batteries and hotter climates. 

Reverse Connection Protection- The charger will detect and indicate a reversed connection on the input and output terminals, preventing damage to the internal circuitry of the unit.

Over and Under Voltage Protection- IDC25L will automatically shut down if it detects an over voltage or under voltage problem, preventing damage to the battery.

Engine bay installation- Sealed to IP67, the IDC is dust, splash and shock proof and can safely operate in extreme temperatures up to 80°C  

Dual charging modes- Engineered to work with both smart and conventional alternators

Over and Under Voltage Protection- IDC25 will automatically shut down if it detects an over voltage or under voltage problem, preventing damage to the battery.

Lithium charging technology- Engineered for use with todays advanced lithium battery technology    

Dual input operation- Simultaneous dual battery charging from both solar and alternator inputs. 

MPPT solar regulator- Using sophiscated MPPT (Maximum Power Point Tracking) solar regulator technology, IDC25L operates as a solar controller, maximising the power generated from panels.                    

Switch mode technology- Featuring the latest synchronous switching technology, IDC25L’s efficiency exceeds 94% at typical full load conditions, converting your vehicle’s 12V DC / 24V DC alternator power to a more complete charge and prolonging battery life. 

Ignition connection- IDC25L can be wired to the vehicle ignition, allowing it to operate only when ignition is turned on. This ignition connection also enables a “low input operation” mode, for compatibility with smart (variable voltage) alternators found in modern vehicles.
