Don’t compromise on Lithium-Ion battery technology


Emergency lighting Announcement


Clevertronics were pioneers in 2012 when they launched the L10 emergency lighting range with lithium batteries. L10 proved to be a game changer, due to the significant savings lighting specifiers and contractors have been able to realise for building owners across Australia and NZ.

Clevertronics engineers undertook years of research and testing with various battery manufacturers to understand which lithium battery was suitable for Emergency lighting applications. The conclusion was clear; only one battery chemistry provided our required outcome; Lithium Iron Phosphate (LiFePO4), also known as LFP. (Lithium Nanophosphate (LNP) which is used in Clevertronics L10 range is a superior type of LFP technology.)

So what makes Lithium Iron Phosphate as opposed to other lithium technologies the right choice for Emergency Lighting?

Emergency and exit luminaires have batteries fitted, which are tested every six months in accordance with AS2293.2 to ensure the products are at a maximum state of readiness to perform when the power fails.

Three critical areas of safety, performance and environmental impact were examined for the three main lithium battery technologies.

i. LFP – Lithium Iron Phosphate (LiFePO4)
ii. LCO – Lithium Cobalt Oxide (LiCoO2 )
iii. NMC – Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2)

LCO and NMC are used commonly in applications such as mobile phones, laptops, toy, hoverboards, scooters and power tools where regular charge and discharge is a common occurrence.




LNP & LFP batteries are thermally stable compared to LCO and NMC batteries, which is critical in an application such as Emergency and Exit lighting.

When batteries are located in areas such as roof cavities that encounter frequent high temperatures and are not readily visible, it is important to utilise a thermally stable battery. In addition, LNP and LFP batteries also have a low capacity loss at high temperatures resulting in a longer life compared to LCO and NMC creating a higher ROI. Finally, LFP batteries do not contain any toxic heavy metals and therefore are more environmentally friendly.

Don’t compromise on these critical factors when you next select an Emergency and Exit Lighting product.
