18650 BATTERY

Grade-A 18650 Cylindrical Bare Cells • High-Drain & High-Capacity • Factory Direct Global Air Shipping

The DXF 18650 Lithium-Ion Bare Cell Collection brings together authentic, factory-fresh Grade-A 18650 cylindrical cells (18mm diameter × 65mm length) from premier global cell manufacturers including Samsung SDI, Panasonic, LG Energy Solution, and DMEGC. Purpose-built for electrical engineers, custom battery pack builders, and commercial assemblers, our lineup covers both high-drain discharge power cells (up to 20A–30A continuous) and maximum-capacity energy cells (up to 3500mAh per cell).

Supplied with standard flat-top terminals ideal for spot welding, every batch is precision voltage-matched and internal-resistance (IR) sorted. Available in flexible multi-pack order tiers from 1 to 100 PCS (1, 10, 20, 50, and 100 PCS bundles) with tiered volume pricing.

🌍 Direct Factory Global Air Shipping

All 18650 cells ship directly from our specialized lithium battery manufacturing and testing facility in China. Every order is packaged with strict terminal insulation and compliance-grade transport casing to guarantee safe arrival.

⚠️ Professional Safety Disclaimer & Usage Restrictions

• Unprotected Industrial Bare Cells: These are bare industrial cylindrical cells without built-in protective circuitry (no integrated PCB/BMS). They are strictly intended for professional integration into battery packs with an external Battery Management System (BMS) or Protection Circuit Module (PCM).
• Mandatory Pack Protection: Custom packs must incorporate cell balancing, overcharge cutoff (max 4.20V), over-discharge cutoff (min 2.50V), short-circuit protection, temperature monitoring sensors, and adequate insulating barriers.
• Prohibited Uses: Do NOT carry loose cells in pockets, bags, or purses alongside metal objects, coins, or keys. Do NOT use in consumer electronic devices lacking built-in battery management, e-cigarettes, or vaporizers.
• Always charge with dedicated lithium-ion microprocessor chargers and store in fire-retardant battery containers.
