Li Auto MEGA with Lianshan Battery Completes First Deliveries in Beijing

On November 6, "Old Tango," head of Li Auto's product line, announced that the new-generation MEGA with the Li Auto self-developed Lianshan battery pack has completed its first batch of deliveries in Beijing. The first-generation MEGA, when launched, was equipped with CATL's 5C Qilin battery, leveraging an 800V high-voltage platform to add 500 km of range with just 10 minutes of charging. Under the previously announced official plan, orders locked before 15:00 on September 7 were slated to receive CATL batteries, while users who placed orders after that time would be switched to Li Auto's self-developed Lianshan 5C ternary battery. Due to tight CATL battery supply, some users who locked in orders in earlier batches received battery swap notices. Li Auto offered two options: accept the Lianshan battery replacement along with 3,500 yuan in benefits, or cancel the order with a full refund of the 5,000 yuan deposit plus an additional 5,000 yuan in compensation. The Li Auto Lianshan battery adopts a self-developed design with contract manufacturing. The cells are produced by Sunwoda and CALB on a contract basis, while Li Auto is responsible for defining the cell solution, BMS, thermal management, and safety systems, and bears the battery warranty responsibility. In terms of specifications, the Lianshan battery in the MEGA has a capacity of 108 kWh, a CLTC range of 710 km, 5C ultra-fast charging capability, a peak charging power of 520 kW, and is compatible with Li Auto's nationwide 5C ultra-fast charging stations. On the technical control side, Li Auto has established tens of thousands of control checkpoints for the Lianshan battery, with full-process cell data traceable for 20 years, six layers of thermal runaway safety defenses, and a self-developed ATR state-of-charge estimation algorithm that keeps SOC estimation error within 3%. According to Li Auto's long-term plan, all future new vehicles will gradually switch to the self-developed Lianshan battery, and CATL will no longer be the standard configuration.
