A LiFePO4 Battery Manufacturer Built Around Custom Programs
What we do
We build LiFePO4 cells, matched modules and finished battery systems — from a 5 kWh wall-mounted home unit to containerised C&I storage and 80 V forklift packs. Every product line is engineered in-house, not sourced and relabelled.
How we work
Prototypes are built on the same production line as volume orders, not in a separate lab. The certification path is identified before tooling, not after — and we state derated capacity up front instead of quoting a nameplate number.


About our Factory
CMX Battery is a high-tech green energy manufacturer dedicated to customised energy storage battery and solar system solutions. The company is headquartered in the HenDong Science Zone Building, Tangxia District, Guangdong Province, with an R&D base in Shenzhen.
Manufacturing runs from a 25,000 m² automated factory equipped with 2 fully automatic and 4 semi-automatic production lines, supported by more than 1,500 m² of office and innovation space, and carries an annual production capacity of 5.8 GWh. The plant serves a global market, exporting to more than 90 countries including the United States, Canada, the United Kingdom, Germany, Australia, the Philippines and Lebanon.
A team of 200+ employees, including 25 R&D technicians, covers lithium-ion module design, cost control and market positioning — the capabilities that decide whether a custom programme is deliverable at volume, and at what price.
Product Lines and Engineering Scope
Specified to your duty cycle, not a catalogue
How the pack is actually built

Cell grading and matching
Every cell is grade-matched and capacity- and internal-resistance-matched per batch. Mismatch is the leading cause of premature pack failure, and it stays invisible until the pack is in the field — which is why it is controlled here and not inspected at the end.

Assembly and process control
Welding, interconnection and enclosure assembly run under process control on the same lines that build volume orders. Prototypes and serial production share tooling, so what you approve is what ships.
Tested to the standards your market requires
Every cross-border lithium battery order ships with UN38.3 test summaries. Products are built to IEC 62619 for industrial Li-ion safety and to UL 1973, with UL 9540A thermal-propagation data for North American ESS approvals.
CB and CE / RoHS documentation covers Europe, CEC covers Australia and CEI-021 covers Italy. Manufacturing runs under ISO 9001, and outdoor enclosures are IP65. Market-specific marks outside this list are scoped per project as a costed line item.
Certification is the difference between a battery that ships and a battery that clears customs. What we cannot shortcut, we will tell you honestly.
