21700 Cylindrical NCM/NCA Cell for Tesla Model 3/Y LR/Performance, Model S/X
Specifications
How we verify OE matching
Every EV battery SKU is cross-checked against the manufacturer's original part number before shipping. Three-step verification process:
-
1
OE number cross-reference. Catalog part number matched against the OEM's published reference for the target vehicle (Toyota, Honda, BYD, Tesla, etc.). Identical OE = guaranteed fitment.
-
2
Cell-level grading. Each pack is assembled from capacity-matched and internal-resistance-matched cells. Voltage, IR, and self-discharge values recorded against the OE spec.
-
3
Diagnostic compatibility check. BMS protocol calibrated to the target vehicle's ECU so the pack registers without re-coding for most hybrid applications.
Description
Engineered specifically for Tesla Model 3 Long Range, Model 3 Performance, Model Y Long Range, Model Y Performance, Model S, and Model X (2017-present), this LIANLI Tesla 21700 Cylindrical NCM/NCA Cell delivers a professional-grade alternative to the OEM 2170 cell reference. 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 equipment. The NCM/NCA chemistry delivers 3.65V nominal per cell with capacity ranges of 4.8-5.0 Ah per 2170 cell. The 21mm x 70mm cylindrical format allows drop-in replacement into OEM module housings used in Model 3/Y LR/Performance packs. Cell matching within 1% capacity and 0.3 milliohm internal resistance ensures balanced packs across series and parallel configurations. Installation on the Tesla Model 3 LR or Model Y Performance 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 2170 module lifted out. The new LIANLI 2170 cell is lowered into the same mounting tray and reconnected using the OEM busbar and BMS harness. Total install time is approximately 120-180 minutes for a qualified Tesla service center with HV-certified tooling. For Model 3/Y LR/Performance owners specifically, the 2170 NCM/NCA chemistry handles the high-performance discharge profile of dual-motor AWD configurations without the deep-cycle damage that LFP cells suffer under sustained high-C-rate loads. The higher energy density (vs. 18650 cells) reduces pack weight by approximately 10% versus equivalent 18650-pack configurations, which improves vehicle handling. Every LIANLI Tesla 2170 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 1000 cells per SKU; trial orders of 200 cells available on request.

FAQ
Frequently Asked Questions
▸ What is the nominal capacity and voltage of the Model 3/Y LR/Performance, Model S/X?
The Model 3/Y LR/Performance, Model S/X 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.
