OEM / ODM Battery Pack Supplier – SAFTEC

SAFTEC is an battery pack manufacturer, supplying OEM / ODM packs to manufacturers, system integrators and large fleet owners.

Complete packs with cells

  • We build LiFePO4 battery packs from qualified, safety-tested cells to meet your lifetime and cost targets.
  • The cells are configured into modules and packs with proper balancing and verification testing.
  • You receive a fully tested, ready-to-install finished battery pack, including the BMS, enclosure, wiring harness and connectors.

Cell-ready packs without cells

  • We design and supply the mechanical enclosure, busbars, wiring harness, BMS, contactors and protections, ready for cell installation.
  • Cell spaces, compression and thermal paths are tailored to your preferred cell format (prismatic, pouch or cylindrical).
  • You can install your own cells, or ask SAFTEC to integrate cells from your nominated suppliers.

Applications of Saftec LiFePO4 Batteries

Our batteries fit many applications, and we are developing more solutions. Share your application, voltage and capacity needs, size limits, and communication requirements, and we will recommend a suitable model or customize a pack.
