Important Information Regarding Rechargeable Lithium Cells - LITHIUM ION (LiIon) & LITHIUM IRON PHOSPHATE (LiFePO4)

Single unprotected cells are not available to customers. For safety information please read the Lithium Battery Safety document
PLEASE NOTE: Under special circumstances, only to pre-qualified customers approved by MI management, cells or packs may be provided without a protection circuit for prototyping or testing purposes. All lithium rechargeable cells/packs supplied by Mi Battery Engineering without a Protection Circuit Module (PCM) will require a duly signed Product Indemnity Waiver (PIW) Click here to download
Do not attempt to charge these batteries using chargers for nickel based batteries or any charger not specifically designed for rechargeable lithium technology.
This cell is manufactured for use in a battery pack assembly. It is not intended for use without a protection circuit. For equipment designed to use individual cells a protection circuit can be incorporated. MI Battery Engineering's current range of protected lithium ion cells can be viewed on this page.
Lithium ion cells can be assembled into single or multi-cell battery packs by authorised pack assembly centres such as our company that have been approved for safety circuit assembly and Lithium Ion pack design.
For information on the safety circuits, more commonly known as a PCM, please click here or follow the links to browse MI Battery Engineering's range of available PCM's for Lithium Ion and Lithium Iron Phosphate.
MI Battery Engineering can also provide advice and components for intelligent Battery Management System's (BMS) addtional to or incorporating PCM's. It's recommended that battery packs especially those featuring complex series/parallel cell assemblies incorporate a BMS in their construction. For further information please consult our sales engineering staff.
For battery pack design enquiries please contact us with your requirements. If you already have some parameters please click here for a Battery Application work sheet & email it to us.

SHIPPING RESTRICTIONS APPLY

Due to IATA and individual airline regulations, this item may only be shipped by surface (road/sea) freight.

NON DG UN3480 LITHIUM ION BATTERIES - Contains cells/batteries exempted from ADG 7.7 & IMDG Code 2020 using Special Provision 188.

Further information on freight & postal regulations for lithium / lithium-based and other battery chemistries can be found on our battery transportation page.
