Lithium Werks was formerly A123 systems

Lithium Werks’ 18650 cells are best for Power.Safety.Life.™ applications. They deliver very high power due to their use of patented Nanophosphate® battery technology. Based on lithium iron phosphate chemistry (LiFePO4), the cells are inherently safe over a wide range of temperatures and conditions. Whether the application requires outstanding cycle life or stable float reliability, the Lithium Werks’ 18650 cells are suitable for a wide variety of power, pulse, or stand-by applications.

Nanophosphate® battery technology offers thermal-stable chemistry, faster charging, consistent output, low capacity loss over time, and superior total cost of ownership (TCO). It provides the foundation for safe systems while meeting the most demanding customer requirements. Multiple layers of protection are employed at the chemistry, cell and system level to achieve an energy storage solution with superior safety and abuse tolerance compared to metal oxide lithium-ion chemistries.

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

  • Single unprotected cells are available to recognised customers. For safety information please read the Lithium Battery Safety document.
  • PLEASE NOTE: All lithium rechargeable cells/packs supplied by Mi Battery Engineering without a 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.
  • Single unprotected cells are available to recognised customers. An indemnity waiver may be required for supply to take place.
  • Lithium ion cells can be assembled into single or multi-cell battery packs by authorised pack assembly centres. 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 battery pack design enquiries please contact us with your requirements.
