18650 Battery Pack for Tesla Model 3 1st Gen (2017–2018)

Product Overview

This product is a high-performance 18650 cylindrical NCA (Nickel Cobalt Aluminum) ternary lithium-ion battery pack, specifically designed and manufactured for the first-generation Tesla Model 3 (2017–2018). It is available in two energy variants: 50 kWh (Standard Range) and 75 kWh (Long Range), serving as the original equipment (OE) power source. Produced primarily by Panasonic, these battery packs utilize thousands of individual 18650 NCA cells, renowned for their exceptional energy density, high discharge efficiency, and long cycle life. Engineered with Tesla's advanced battery management system (BMS) and integrated thermal management, this battery pack delivers the balance of long-range cruising, rapid acceleration, and reliable durability that defined the debut Model 3.
