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.

Victron Smart isolated DC-DC charger:

The Orion-Tr Smart DC-DC charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth. For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch and has an engine running detection mechanism.

The Orion Tr-Smart charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Models are available up to 400W and unlimited multiple units can be connected in parallel to increase output power. Suitable for high temperatures up to 55°C with a full rated output up to 40°C. 
The Orion Smart DC-DC chargers can be used as a power supply or as a battery charger. In charger mode the three-state charge algorithm will increase battery life by properly charging the battery. Especially in the case of vehicles with a smart alternator, or voltage drop caused by long cable runs, controlled charging is indispensable. Controlled charging will also protect the alternator in lithium systems where direct charging can overload the alternator due to the low impedance of the lithium battery. In fixed output mode the output voltage will remain stable independent of the applied load or varying input voltage (within the specified range).

The Orion Smart DC-DC charger can be set up to only provide power when the engine is running. This is possible thanks to the built-in engine shutdown detection. This also prevents the onboard voltage of the vehicle from becoming too low. It is not necessary to intervene in the system of the vehicle, to install a separate motor run sensor or to intervene in the CAN-bus system. Apart from this detection, the Orion Smart DC-DC charger can also be activated by a forced allowed to charge feature, e.g. connected to the ignition switch.

The Orion-Tr Smart DC-DC Charger is fully programmable with the VictronConnect app. 



Bluetooth Smart enabled- Any Bluetooth enabled smart phone, tablet or other device can be used to monitor, to change settings and to update the charger when new software features become available.

Fully programmableBattery charge algorithm (configurable) or fixed output. Smart alternator compatibility: engine running detection mechanism.

Adaptive 3-stage charge algorithm: bulk – absorption – float- For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. For lithium batteries absorption time is fixed, default 2 hours. Alternatively, a fixed output voltage can be chosen.

Remote on-off- A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two pole connector can be switched to battery minus (or the chassis of a vehicle, for example).

All models are short circuit proof and can be paralleled to increase output current-  An unlimited number of units can be connected in parallel.

High temperature protected- The output current will reduce at high ambient temperature.

IP43 protection- When installed with the screw terminals oriented downwards.

Screw terminals- No special tools needed for installation.

*Please note as per page 10 on the Victron manual, 60A circuit protection is required on both sides of the unit (start battery and auxiliary battery). Minimum cable size is 10mm2.
