Product description
Product Overview
This 18650 cylindrical NCA ternary lithium-ion battery cell is a direct OEM replacement, specifically engineered for Tesla Model X (2015-2019) with exclusive OE part number 1088790-00-B. Adopting premium nickel-cobalt-aluminum (NCA) cathode material consistent with Tesla’s original 18650 battery specifications—used in Model X 90kWh packs with dual-motor all-wheel-drive systems—it delivers stable energy density (262Wh/kg), reliable electrical performance and superior single-cell consistency. It perfectly matches the original battery module structure, vehicle BMS (Battery Management System), and Tesla’s proprietary liquid cooling thermal management system, widely applied for Tesla Model X battery pack repair, module refurbishment, capacity recovery and aftermarket replacement, complying with strict automotive-grade reliability standards and meeting B2B OEM/aftermarket demands.
Key Features
- Exact OE replacement with part number 1088790-00-B, fully compatible with Tesla Model X (2015-2019) original battery packs that use 18650 cylindrical cells, the tried-and-tested cell format for Tesla’s flagship Model X.
- Standard 18650 cylindrical form factor (18mm diameter × 65mm height), equipped with premium NCA ternary lithium cathode material as original OEM specification—NCA chemistry is Tesla’s premium choice for high energy output and performance, ideal for Model X’s luxury positioning.
- Stable high energy density (262Wh/kg), supporting stable high-current discharge to meet the power demands of Tesla Model X’s dual-motor all-wheel-drive system and 90kWh battery pack configuration, ensuring excellent range and acceleration performance.
- Low internal resistance (≤33mΩ), ultra-low self-discharge rate and long cycle life (≥1100 cycles), ensuring long-term performance stability and reducing replacement frequency for B2B clients, aligning with Tesla’s battery durability standards.

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.
