Product description
Product Overview
This 4680 Cylindrical High-Nickel NCM Ternary Lithium Battery (Tabless) is an OEM replacement for Tesla Model S (2021-present), with OE numbers 1001865-00-E, 1001865-00-F, 1001865-00-A. It features Tesla’s revolutionary tabless design, high-nickel NCM cathode, and dry electrode technology, delivering exceptional energy density, fast charging, thermal stability, and long cycle life. Engineered for structural battery pack integration, it boosts vehicle range, power output, and manufacturing efficiency while lowering costs.
Key Features
- Tabless (Full Tab) Design: Eliminates traditional tabs, reduces internal resistance, improves current distribution, cuts heat generation to 20% of conventional cells, and enables 6x faster charging.
- High-Nickel NCM Cathode: NCM 811/911 chemistry maximizes energy density (up to 300 Wh/kg) and reduces cobalt usage.
- Large Cylindrical Format: 46mm diameter × 80mm height, 5x more energy than 2170 cells, fewer cells per pack, simplified assembly.
- Dry Electrode Technology: Streamlines production, lowers costs, enhances consistency.
- Superior Thermal Management: Optimized heat dissipation, fewer hotspots, improved safety and lifespan.
- OEM Compatibility: Direct fit for Tesla Model S (2021-present), matches OE specs 1001865-00-E/F/A.
- High Power & Long Cycle Life: Supports high discharge rates, reliable performance over extended cycles.

FAQ
Frequently Asked Questions
▸ What is the nominal capacity and voltage of the cell?
The cell delivers its rated capacity at 3.2V nominal (charge to 3.65V, discharge to 2.5V). Capacity is measured at 0.5C discharge rate after standard formation cycles. Internal resistance is below 0.25 milliohm for prismatic cells.
▸ Can these cells be used in series and parallel configurations?
Yes. Cells can be configured in series (1S to 16S typical packs) and parallel (1P to 4P) for 12V, 24V, 48V, and high-voltage 400V/800V systems. Cell matching within 2% capacity and 0.5 milliohm internal resistance ensures balanced packs.
▸ What cycle life can I expect?
LIANLI LFP cells deliver 6000+ cycles at 80% DoD, 4000+ cycles at 90% DoD, and 2000+ cycles at 100% DoD. Capacity retention remains above 80% throughout the rated cycle life when operated within specified charge/discharge rates and temperature ranges.
▸ What certifications apply to these cells?
All LIANLI LFP cells carry UN38.3, IEC62619, UL1973, CE, GB/T 36276, and MSDS certifications. Cells are manufactured in ISO9001/14001 facilities with automated electrode coating, stacking, and electrolyte filling under dry room conditions (Dew point below -40C).
▸ Do you ship internationally and what are minimum order quantities?
Yes. Sample orders accepted from 4 pieces for evaluation. Bulk orders ship via sea freight in custom wooden cases with anti-static and shock-proof packaging. DDP terms available for major destinations. Air freight available for urgent orders up to 500kg.
