21700 Cylindrical NCA/NCM Battery Pack for Tesla Model 3 (2018-2026, Long Range Battery Module) OE#1137375-01-K
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.

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.
