MOLICEL 18650

The Molicel 18650 Series Cylindrical Lithium-Ion Bare Cell Lineup represents industry-leading rechargeable battery engineering from E-One Moli Energy. Renowned across the globe by professional battery pack assemblers, EV engineers, and DIY innovators, Molicel's 18650 platform delivers an outstanding balance of energy density, high discharge capability, low internal resistance, and superior thermal stability. Featuring benchmark models including the ultra-high capacity INR18650-M35A (3500mAh, 10A) and the legendary ultra-high drain INR18650-P28A (2800mAh, 35A), these authentic flat-top bare cells provide reliable 3.6V/3.7V nominal building blocks for high-performance custom battery packs.

Key Features:

• High-Drain & High-Capacity Choices: Choose between maximum energy reserve with the 3500mAh M35A for extended runtimes, or explosive 35A high-current output with the P28A for heavy motor loads.
• Ultra-Low Internal Resistance (IR): Advanced electrode coating and current-collector design minimize heat buildup under demanding charge and discharge cycles, significantly improving pack life.
• Classic 18650 Form Factor: Industry-standard dimensions (approx. 18.3 mm diameter × 65.2 mm length) ensuring broad mechanical compatibility with modular pack holders, enclosures, and brackets.
• Clean Flat Top Terminals: Unraised positive terminals precision-formed for consistent manual or automated resistance spot-welding with pure nickel strips.
• Strict Factory Grade-A Sorting: Sourced factory-fresh and screened for matched voltage curves and uniform internal cell resistance across all package tiers.
• High-Rate Charging Support: Built to safely accept high-current CC/CV charge rates under proper thermal control and smart battery management.

Safety & Usage Restrictions (Important Bare-Cell Notice):

• Unprotected Bare Cell Warning: These are bare industrial cylindrical cells without built-in protection circuit boards (no integrated PCB/PCM).
• Professional Assembly Only: Strictly intended for qualified pack builders and technicians who integrate an appropriate Battery Management System (BMS) with overcharge, over-discharge, over-current, short-circuit, and cell balancing protection.
• Never Carry Loose Cells: Do not carry loose cells in pockets, bags, or toolboxes where contact with keys, coins, or metal objects can cause catastrophic short circuits. Always store in non-conductive plastic battery cases.
• Prohibited Consumer Uses: Not for loose consumer use in flashlights, vaping devices/e-cigarettes, or household appliances lacking dedicated cell containment and BMS protection.
• Charging Protocol: Charge exclusively using dedicated CC/CV lithium-ion smart chargers. Never exceed 4.20V per cell and never leave charging batteries unattended.
• Pre-Weld Inspection: Verify equal cell voltages and inspect outer shrink-wrap insulation prior to resistance spot-welding. Never solder directly onto cell terminals with a soldering iron.

Recommended Applications:

• Electric Bicycles (E-Bikes), Electric Scooters, and Light Electric Vehicles (LEVs)
