Intended Use & Restrictions

For professional battery-pack manufacturers, technical service providers, system integrators and other qualified entities able to design, assemble and test lithium-cell packs. Manufacturer names and model designations identify factory origin and model only; seller authorization is not claimed unless stated separately.

Usage & Safety Guidelines

• Not a ready-to-use consumer battery; it has no individual protection circuit. Use only in 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 loose replaceable cell in e-cigarettes, flashlights, toys, power banks, RC devices or other consumer devices unless integrated into a professionally made and protected pack.
• Never carry loose in a pocket or bag with metal objects. Short circuits can cause fire, explosion, burns or property damage.
• Reject cells with abnormal voltage, damaged casing, corrosion or other abnormal conditions. Verify equal voltages before connecting reclaimed cells.
• Do not solder directly to terminals without an assembly procedure approved by a professional integrator. Follow the pack design and cell documentation.

Why Choose DXF?

Select the quantity appropriate for your professional project, and inspect, match and protect every reclaimed cell before assembly.
