21700 Battery Pack for Tesla Model 3 2nd Gen (2018–2026）
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.
