High-capacity cells optimized for severe tropical environments, reliable power tools, and local energy storage systems.
Vietnam has emerged as one of the most dynamic manufacturing hubs in Southeast Asia. Driven by the global relocation of electronic supply chains, aggressive national digitalization, and a commitment to green energy transitions under the Power Development Plan VIII (PDP8), the demand for advanced energy storage and high-capacity batteries has surged exponentially. From Hanoi's industrial corridors to Ho Chi Minh City's high-tech parks, industrial enterprises are seeking robust battery solutions that can withstand tropical environments while delivering high energy density and structural safety.
SEO Insight: High-capacity batteries with NCM (Nickel Cobalt Manganese) and LFP (Lithium Iron Phosphate) chemistries are key drivers in Vietnam's transition toward smart manufacturing, e-scooter fleets, and decentralized solar power grids.
Vietnam ranks second globally in motorcycle ownership, and the local market is undergoing a structural shift toward electric two-wheelers (E2Ws). Major cities like Da Nang, Hai Phong, and Ho Chi Minh City are implementing strict emission reduction targets. To support this transition, local E2W manufacturers and fleet operators require high-density cylindrical lithium-ion batteries (such as 21700 and 18650 models) that offer long endurance, high rate discharge, and extended cycle lives. Custom battery packs configured with cells like the 21700 5000mAh and 5800mAh provide the necessary energy storage to support long-distance commutes on a single charge under Vietnam's congested urban traffic conditions.
With Vietnam's rapid solar PV installation boom over the last decade, particularly in regions like Binh Thuan and Ninh Thuan, grid stability has become a primary concern. The Vietnamese government is heavily encouraging the integration of Battery Energy Storage Systems (BESS) for both residential and commercial solar setups. Furthermore, the expansion of 5G telecom towers by major local operators (such as Viettel, Vinaphone, and Mobifone) requires reliable, long-lasting backup power. Lithium Iron Phosphate (LFP) batteries, specifically the 26700 4300mAh format, have become the preferred choice due to their superior thermal stability, safety profile, and ability to handle deep discharge cycles in tropical climates without active cooling systems.
Sichuan Changhong New Energy Technology Co., Ltd. — Your Trusted Energy Partner
Sichuan Changhong New Energy Technology Co., Ltd. was founded in October 2006. As a subsidiary of Changhong Holding Group (one of the World’s Top 500 Brands), it is a national high-tech enterprise integrating R&D, manufacturing and sales of full-range alkaline batteries and lithium-ion batteries.
The company now operates six manufacturing bases in Mianyang (Sichuan), Jiaxing (Zhejiang), Taixing (Jiangsu), Huarong (Hunan), Shenzhen (Guangdong) and Chonburi (Thailand). It has an annual production and sales capacity of 3.5 billion alkaline manganese batteries, 600 million cylindrical lithium-ion batteries (including 18650, 21700, 26700 and other models), over 100 million small polymer batteries and over 100 million battery PACK sets.
It controls three subsidiaries: Zhejiang Changhong Feishi Electrical Appliance Industry Co., Ltd., Changhong Sanjie New Energy Co., Ltd., and Shenzhen Changhong Juheyuan Technology Co., Ltd.
The company is a listed enterprise in China (Stock Code: 920239), Top 100 Chinese Battery Companies, Vice Chairman Unit of China Battery Industry Association, Member of IEC Technical Committee on Primary Batteries, National High-Tech Enterprise, National Specialized, Sophisticated, Unique and New "Little Giant" Enterprise, the largest production base of high-rate cylindrical lithium batteries in Western China, National Green Factory, Sichuan Provincial Advanced Smart Factory, and included in the MIIT 5G Factory List.
When deploying custom high-capacity batteries in Vietnam, selecting the correct chemical composition is essential to balance energy density, cost, safety, and ambient thermal tolerance. Changhong New Energy provides two primary battery technologies to cater to diverse Vietnamese commercial applications:
NCM and NCA chemistries represent the pinnacle of high energy density. Cells like the 21700 5800mAh and 18650 3500mAh pack massive energy capacity into compact form factors. This makes them ideal for:
LFP chemistry excels in thermal stability and safety. Vietnam's ambient temperatures can regularly exceed 40°C in the summer. LFP cells, such as the 26700 43E, offer safe operation even under high thermal loads, with a lifespan exceeding 2,000 to 3,000 cycles. Key applications include:

A Journey of Technological Evolution and Global Expansion
Changhong introduced advanced technologies and equipment for alkaline manganese batteries from Toshiba, entering the primary battery sector.
Changhong New Energy was independently registered and officially operated.
Introduced the world’s high-end Haiba production line for alkaline batteries.
Changhong Energy listed on the New Third Board; acquired Zhejiang Feishi to build a coastal production and export base.
Acquired Jiangsu Sanjie, entering the cylindrical lithium battery industry.
Established Mianyang Jiechuang, realizing large-scale capacity expansion of alkaline batteries and lithium batteries.
Changhong Energy officially listed on the Beijing Stock Exchange (Stock Code: 920239).
Acquired Shenzhen Juheyuan, entering the polymer lithium battery sector. Changhong Sanjie’s cylindrical lithium battery capacity exceeded 500 million units.
Hunan Changhong Juheyuan polymer battery capacity expanded. Preparation for Changhong New Energy Thailand Plant commenced.
Changhong New Energy Thailand Plant officially went into operation. Total alkaline battery capacity exceeded 3.5 billion units. This strategic plant in Thailand provides trade advantages for importing high-capacity batteries directly to Vietnam and other ASEAN countries.
For Vietnamese manufacturing firms and industrial purchasers, sourcing components from reliable ASEAN neighbors is highly advantageous. With the official launch of the Changhong New Energy Thailand Plant in Chonburi in 2025, we have optimized our supply chain specifically for the Southeast Asian region. Under the ASEAN Trade in Goods Agreement (ATIGA), importing batteries from our Thailand facility to Vietnam allows businesses to benefit from zero or highly reduced import tariffs, simplified customs clearances, and significantly lower transit times compared to shipping from mainland China.
Global supply chain volatility has highlighted the necessity of localized sourcing. By establishing our manufacturing presence in Thailand, Changhong New Energy ensures that Vietnamese OEMs (Original Equipment Manufacturers) in the e-scooter, electric bike, power tool, and energy storage sectors have access to a stable, continuous supply of high-capacity lithium-ion cells. Our smart factories utilize state-of-the-art 5G-enabled automation, ensuring that every batch of 18650, 21700, and 26700 batteries complies with international quality benchmarks (IEC, UN38.3, UL) before reaching Vietnamese ports like Hai Phong or Cat Lai.
Vietnam's unique geography spans tropical monsoon zones with high humidity and temperature fluctuations. Standard battery packs often suffer from rapid capacity fade or safety degradation under these conditions. Changhong's engineering team offers specialized battery custom pack designs featuring advanced battery management systems (BMS), high-grade thermal insulation, and robust sealing technologies. This customization ensures that our high-capacity batteries maintain stable energy output and operate safely in industrial zones from Bac Ninh in the north to Long An in the south.
