Lithium Batteries Now With 7-Year Warranty, Bluetooth Functionality & IEC Certified

Invicta Lithium batteries are a premium range of the highest quality Lithium Iron Phosphate (LiFePO4) composition. Lithium Iron Phosphate (LiFePO4) was selected for our range due to its inherent safety features. When comparing LiFePO4 to other Lithium technologies there are some distinct safety advantages. These advantages include greater tolerance to both high temperatures and abuse such as overcharging, short circuit and penetration. As a result of these features the risk of fire is extremely low even under harsh circumstances.

As well as utilising LiFePO4 technology, the Invicta lithium batteries range also includes a built in Battery Monitoring System (BMS) to further protect against over charge or discharge, over temperature and short circuit all critical for the safety of the battery. As an added benefit, Phosphate is not a hazardous material and so is friendly both to the environment and health. INVICTA LiFePO4 Lithium Batteries

The Invicta Lithium batteries range now comes with IEC Certification on both the BMS and Cells*. This certification has been obtained through thorough testing of the product and a complete audit of the factory. The IEC Certification is a huge tick of approval for safety and quality, and peace of mind.

The Invicta Lithium range comes with all the benefits of LiFePO4 composition in either the standard 12V SLA case sizes or 24V versions for larger applications.

With 3.2V per cell the Invicta Lithium range is ideally suited for replacement of equivalent sizTUV Mark IEC certificatione SLA with the extra benefits of up to 8 times the cycle life, greater utilisation of available capacity through increased Depth of Discharge (DOD) and fast charging. All of this at close to half the weight makes them ideal for deep cycle and mobility applications.

With the all new SNL range you can even monitor the health and status of your batteries on your phone via Bluetooth wireless communication.
