Intended Use & Restrictions

Intended only for professional customers, including battery-pack manufacturers, technical service providers, system integrators and entities qualified to design, assemble and test packs built from lithium cells. Manufacturer names and model designations identify factory origin and model only; seller authorization by the manufacturer is not claimed unless expressly stated separately.

Usage & Safety Guidelines

• The cell is not a ready-to-use consumer battery and has no individual protection circuit. Integrate only into a professionally designed pack with appropriate BMS/PCM, insulation, housing and protection against short circuit, overcharge, over-discharge and overheating.
• Do not use as a single, loose, replaceable battery in e-cigarettes/vapes, flashlights, toys, power banks, RC devices or other consumer devices unless part of a professionally made and protected pack.
• Do not carry loose in a pocket or bag with metal objects. A terminal short circuit can cause fire, explosion, burns or property damage.
• Do not use a damaged cell, including one with voltage below documented limits, a crushed casing, corrosion or other abnormal condition.
• Do not solder directly to terminals without technology and procedure approved by a professional integrator. Follow the pack design and documentation.
• Before assembly, inspect reclaimed cells and independently verify equal voltages of cells to be connected.

Why Choose DXF?

Choose the quantity appropriate for your professional pack-building project, then verify reclaimed cell condition, matching and protection design before use.
