18650 Cylindrical NCA Cell for Early Tesla Model S/X, Roadster

Specifications

Description

Engineered specifically for the early Tesla Model S (2012-2017), early Model X (2015-2017), and the original Tesla Roadster (2008-2012), this LIANLI Tesla 18650 Cylindrical NCA Cell delivers a professional-grade alternative to the original 18650 cell reference used in the first generation of Tesla's high-voltage battery packs. Each cell is factory-balanced and tested under simulated load conditions to ensure the same voltage profile, regenerative charging acceptance, and thermal behavior as the original Panasonic NCR18650B cells that shipped with these vehicles. The NCA chemistry delivers 3.65V nominal per cell with capacity ranges of 3.0-3.5 Ah per 18650 cell. The 18mm x 65mm cylindrical format allows drop-in replacement into OEM module housings used in early Model S packs (16 modules of 444 cells per pack). Cell matching within 1% capacity and 0.3 milliohm internal resistance ensures balanced packs across series and parallel configurations up to 96S16P. Installation on the early Tesla Model S or Roadster follows the standard OEM service procedure. With the high-voltage system safely discharged and isolated, the pack cover is removed, the high-voltage interlock released, and the existing 18650 module lifted out. The new LIANLI 18650 cell is lowered into the same mounting tray and reconnected using the OEM busbar and BMS harness. Total install time is approximately 180-240 minutes for a qualified Tesla service center with HV-certified tooling due to the larger module count. For early Model S/X owners specifically, the 18650 NCA chemistry handles the high-performance discharge profile of dual-motor AWD configurations with proven long-term reliability (the original 18650 packs are now 12-14 years old in service). Replacing worn cells with fresh LIANLI 18650 NCA cells restores pack capacity to within 5% of original specification. Every LIANLI Tesla 18650 cell ships with a 12-month limited warranty covering manufacturing defects and premature capacity loss below 70% of rated specification. Cross-border logistics is handled through established freight forwarders in Hong Kong, Shenzhen, and Shanghai, with DDP options available for buyers in the United States, Germany, the United Kingdom, France, the Netherlands, Italy, Spain, Poland, the UAE, Saudi Arabia, and South Africa. Typical transit time is 7-12 business days for air-freight orders and 28-35 days for sea-freight container orders. MOQ is 2000 cells per SKU; trial orders of 500 cells available on request.
