Li-Ion batteries

Lithium technology has made great strides in recent years and at Celltech we possess both great knowledge and a broad range of this type of battery. Lithium cells, which are primarily characterized by their high energy density, also have safety risks. We therefore focus exclusively on projects and sales of product ranges where we have full control of the development process and can ensure that the proper charging and safety electronics are used. We therefore do not sell just the cells, when we do not have full insight into the area of use.

To develop a specially designed lithium-ion (Li-ion) battery is now surrounded with testing and transportation requirements. To simplify for you in need of recharging only Li-ion batteries, we at Celltech developed several batteries that make it easier for you to get ahead in your product development. Here we have batteries that meet the transportation requirements UN38.3 and is ready to be built into your product. Need to find a special design with mechanical or electrical challenges, we are at your service to help.

Advantages of the standard Li-ion batteries:
• Tested and approved for carriage under UN38.3
• Reduces the “time to market”
