Xiaomi has announced a new “Dragonscale” (Longjia) battery for its Skynomad SUV models. Developed in partnership with CALB and Sunwoda, the tech giant is offering a lifetime safety guarantee for the new battery, covering spontaneous combustion and post-collision fires.

Xiaomi’s guarantees

Li Xiaoshuang, vice-CEO of Xiaomi’s automotive arm, says the Dragonscale battery far exceeds China’s national standards for cycle life, thanks to strict raw-material vetting and optimised manufacturing and design.

In the case of self-ignition due to quality defects, Xiaomi is offering a free car of equal specification and trim level as compensation. The tech giant is also covering battery fires caused by collisions or underbody damage, pledging to cover the difference between insurance payouts and the car’s pre-loss market value.

In the fine print, Xiaomi says the safety guarantees apply only to non-commercial first-owner cars, which rules out rideshare drivers, rental cars, and pre-owned vehicles. Owners must also subscribe to Xiaomi’s connected vehicle services and service their cars at official Xiaomi centres.

What’s new with the Dragonscale battery

Beyond cycle life, Xiaomi claims the Dragonscale battery exceeds China’s national standards in other areas. It says Dragonscale packs feature high-voltage isolators with millisecond-level switching times and redundant insulation materials.

The battery also comes with a Xiaomi-developed “Cloud BMS” (battery management system), which claims to monitor cell condition with “cloud-based AI inspectors continuously”. Xiaomi asserts that the BMS samples cell data 10 times more frequently than the national standard, with 3 times the data size.

Xiaomi says that all these measures allow the Dragonscale battery to react to incidents or failures in milliseconds. In high-temperature (55 °C) and full SoC (state of charge) testing, the tech giant claims that individual cell fires will not spread to the rest of the pack.

Which cars will get Dragonscale?

In a Weibo post, Xiaomi Auto says that the Dragonscale battery will debut alongside the Skynomad EREV SUV lineup on September 7. The new battery is expected to be equipped on the N90 and N70 at launch.

However, it has not been disclosed whether the new battery will make its way into the SU7 sedan or YU7 SUV. The two models currently feature batteries from both CATL and BYD’s FinDreams.

China EV DataTracker reports that Xiaomi delivered 31,267 cars in China in July 2026. This is down by almost half from December 2025, when the tech giant delivered 50,212 units in a single month.

While Xiaomi lost over 5,600 USD on every car in Q1 2026, the Skynomad lineup may prove to be a profitable volume seller.
