Custom battery packs

Enix Power Solutions is specialised in designing battery solutions to meet your specific product requirements.

Whether you need rechargeable or Primary, Lithium-Ion or Lithium Thionyl Chloride, simple or complex, we design custom battery packs that are fit for purpose. We will identify the correct battery technology to ensure the battery is physically and electrically suitable, with appropriate safety and electronic circuits. We get the right certifications so you can ship your custom batteries all over the world.


Technical support

After collecting application data, we can begin structuring our design process for your product. We will carry out a design review and look at space constraints, run time expectations, power consumption and environmental considerations. Once we understand exactly what the battery is expected to do, we will begin creating innovative solutions and a proposal document for your battery pack. Involved at all stages, you can shape the product with our dedicated engineers and have full awareness of development whilst relying on us to deliver against an agreed timeline.

Using a combination of off-the-shelf test equipment and bespoke in-house test equipment, cells and battery packs are tested before leaving our manufactures to ensure proper operation and to condition cells to operate to their full capability from the first use.
