Residential energy storage batteries typically cost between 2500 and 3500 yuan/kWh. A mainstream 10kWh system would cost approximately 25,000 to 35,000 yuan. The specific price is significantly affected by brand, technology, capacity, and configuration.
Key Factors Affecting Price
Battery Type
Lithium Iron Phosphate (LiFePO₄) Batteries: The mainstream choice, offering high safety and long lifespan (over 6000 cycles), accounting for 55%–70% of the cost.
Ternary Lithium/Lead-Acid Batteries: Less commonly used in residential applications; the former is expensive and unstable, while the latter has a short lifespan and is obsolete.
Brands and Technology
Leading brands (such as BYD, CATL, and Narada) command a premium of approximately 15%–30% due to their advanced BMS systems and long cycle life.
EITAI's 11.52kWh liquid-cooled battery is priced at approximately 24,700 yuan, featuring liquid cooling and a high cycle life (≥8000 cycles), suitable for high-temperature regions. Thermal Management Methods
Air-cooled system: Lower cost, suitable for temperate regions.
Liquid-cooled system: More precise temperature control, extends battery life, but price is 20%–30% higher.
Raw Material Cost Fluctuations
In 2025, the lowest price for energy storage cells reached 0.26 yuan/Wh (260 yuan/kWh), but due to the rebound in lithium carbonate prices, the average system price in 2026 has rebounded to 0.6–0.8 yuan/Wh.
As of March 2026, the winning bid price for some 2-hour energy storage systems has approached 0.7 yuan/Wh (700 yuan/kWh).
