Product description
Product Overview
This 4680 Cylindrical High-Nickel NCM Battery is an OEM replacement for Tesla Model Y (2023–Present), matching OE numbers 1666969-55-F, 1666969-56-G, and 1666968-99-C. Engineered with Tesla’s tabless electrode and high-nickel NCM chemistry, it delivers 5x higher energy capacity, 6x greater power output, and superior thermal stability vs. legacy 2170 cells. Built for structural battery pack integration, it boosts range, charging speed, and reliability for Model Y Long Range/Performance variants.
Key Features
- High-Nickel NCM Chemistry: 8:1:1 Ni:Mn:Co ratio for exceptional energy density and cycle life.
- Tabless Electrode Design: Reduces internal resistance by ~90%, enabling ultra-fast charging (up to 500kW peak).
- 4680 Cylindrical Format: 46mm diameter × 80mm height; 5x volume vs. 2170 cells, fewer cells per pack.
- Structural Pack Compatibility: Direct fit for Tesla’s CTC (Cell-to-Chassis) architecture.
- OEM-Grade Quality: Meets Tesla’s factory specs for performance, safety, and durability.
- Enhanced Thermal Management: Lower heat generation for consistent performance in extreme conditions.
- Longer Driving Range: ~16% improved range vs. 2170-equipped models.

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.
