Explore our premium range of custom OEM / ODM power storage products engineered for high performance, reliability, and regulatory compliance.
The global transition toward carbon neutrality has accelerated the demand for large-scale, intelligent, and scalable Electric Power Storage (ESS) solutions. Modern grid topologies rely heavily on intermittent renewable sources like solar and wind, making grid-stabilizing batteries no longer optional, but fundamental. Modern factory infrastructures must pivot from simple assembly processes to advanced system integration, incorporating artificial intelligence, smart thermal regulation, and high-voltage efficiency protocols.
As a leading custom OEM electric power storage factory, we address the unique technical and operational complexities faced by utility developers, EPC (Engineering, Procurement, and Construction) contractors, and commercial scale enterprises. We deliver multi-layered system protection, active Balancing BMS (Battery Management Systems), and modular design capabilities to provide reliable energy reserves in various climate regions around the globe.
Navigating global procurement requires reliable systems that balance upfront Capital Expenditure (CAPEX) with long-term Operational Expenditure (OPEX).
Global procurement teams prioritize minimizing the Levelized Cost of Storage (LCOS). Through our optimized supply chain, raw material integration, and high automation, our factory offers customized storage systems that maximize ROI.
Thermal runaway prevention and failure analysis are non-negotiable. Our OEM battery systems integrate premium LiFePO4 cells with multi-tier battery management systems, aligning with UL 9540A and CE certifications.
Whether you need compact wall-mounted systems, expandable stackable modules, or high-voltage multi-megawatt container configurations, our OEM production lines adapt to your specified design requirements.

From centralized grid services to microgrid integration, our systems provide scalable, localized energy resilience.
For modern manufacturing facilities, commercial real estate, and critical infrastructure, electricity demand charges can account for a large portion of operational utility costs. Our high-voltage container solutions, ranging from 100kW to multi-megawatt systems, store cheaper off-peak electricity and discharge it during peak grid demand windows. This reduces demand fees while stabilizing the facility's incoming power profile.
Developing robust power infrastructure in remote settings (such as mining operations, isolated island communities, and off-grid resorts) requires combining solar arrays, wind turbines, and diesel generation. Our containerized battery energy storage systems (BESS) act as the central microgrid controller, handling grid frequency stabilization, black-start capabilities, and voltage regulation to minimize dependency on expensive imported fuel.
Modern data centers demand continuous uptime. High-density, modular cabinet battery systems serve as a reliable line of defense against utility anomalies. By replacing lead-acid configurations with LiFePO4 chemistry, data centers benefit from higher power density, reduced footprint, longer service life, and lower cooling overheads.
Base transceiver stations (BTS) operate in environments with varying temperature ranges and fluctuating grids. Our embedded power systems (such as the ETP48600 series) deliver clean DC electricity to critical telecom gear. By integrating smart lithium packs, operators can cycle their systems under high ambient temperatures without premature aging, outperforming traditional lead-acid alternatives.

By combining technical expertise, flexible production capacity, and customer-focused support, the company aims to be a trusted partner for organizations seeking reliable and scalable energy storage technologies in the rapidly evolving global energy market.
Our OEM manufacturing facility is built on rigorous testing, advanced cell sorting, and redundant safety engineering.
Lithium Iron Phosphate (LiFePO4) is the benchmark chemistry for stationary energy storage systems. Its structural integrity under thermal stress, lack of oxygen release during failure, and high cycle counts make it the safest choice for residential environments and large-scale utility layouts.
Most commercial systems use passive balancing, which dissipates excess charge as heat. Our high-voltage solutions offer active balancing, transferring energy from high-charge cells to lower ones. This maximizes the usable capacity of the battery pack and extends the lifespan of the system.
Our rack-mount, stackable, and containerized battery designs prioritize ease of installation and replacement. Modular architectures allow operators to scale up system capacity as demand increases, reducing initial CAPEX while safeguarding future performance.
