High-capacity industrial battery storage, smart communication BMS modules, and liquid-cooled ESS designed for scalable OEM/ODM global deployment.
The global transition toward decentralized clean energy infrastructure requires highly dependable, thermally stable, and economically viable energy storage technologies. As governments and commercial enterprises accelerate decarbonization mandates, the demand for custom OEM energy storage systems (ESS) has shifted from generic off-the-shelf battery packs to tailor-engineered high-density storage architectures. Modern electrochemical energy storage is no longer merely a backup safeguard; it serves as a critical asset for peak shaving, load leveling, frequency regulation, and microgrid stabilization.
Shenzhen Suntherra Battery Co., Ltd. stands at the forefront of this industrial revolution. Established in 2014 in the tech innovation hub of Shenzhen, China, Suntherra has grown into a premier OEM and ODM manufacturer specializing in advanced solar lithium iron phosphate (LiFePO4) batteries, tubular OPzS/OPzV flooded batteries, deep-cycle AGM/Gel units, and liquid-cooled utility-scale storage systems. Spanning a state-of-the-art production base of over 12,000 square meters and backed by 180+ veteran electrochemistry engineers and R&D experts, Suntherra provides end-to-end custom battery manufacturing services to global engineering procurement construction (EPC) contractors, solar integrators, and industrial power providers.
Key Takeaway for B2B Procurement Decision-Makers: Suntherra integrates proprietary Smart BMS communication protocols (CANbus, RS485, Modbus TCP) with Tier-1 grade-A prismatic cell technology, ensuring thermal safety margin compliance under extreme climate operational conditions while minimizing Levelized Cost of Storage (LCOS).
From single-cell matching to liquid-cooled containerized megawatt ESS, explore our hardware and software modularity designed for industrial reliability.
Suntherra utilizes premium lithium iron phosphate chemistry featuring ultra-stable olivine crystal structures. Integrated with high-precision Active Balancing BMS, cell-to-cell voltage variance is strictly controlled within ±0.005V, preventing thermal runaway and extending operational lifecycle beyond 15 years.
For high-capacity C&I installations (e.g., 200kWh - 2MWh), our liquid cooling architecture maintains internal core battery temperature delta ≤ 3°C. Compared to traditional forced-air cooling, energy consumption is reduced by 30% while extending total energy throughput by up to 20%.
For remote telecom base stations and harsh ambient environment projects where freezing or high heat occurs, our nano-gel electrolytes and tubular die-cast spine plates offer maintenance-free operation and exceptional deep recovery performance.

Shenzhen, China, is widely recognized as the global epicenter of electrochemistry innovation and hardware manufacturing. Suntherra leverages this hyper-integrated ecosystem to deliver unparalleled procurement advantages to international clients. By sourcing Tier-1 battery cells directly from localized high-volume partners and carrying out automated SMT assembly, laser welding, and dynamic BMS aging tests under one roof, we eliminate unnecessary intermediary markups and reduce delivery lead times by up to 35%.
Our 12,000 square meter factory operates multiple fully automated production lines equipped with CCD visual alignment systems, automatic cell sorters, and dual-axis laser welding robots. Every battery pack undergoes rigorous multi-stage quality control, including high-potential insulation testing, vibration simulation, and 100% capacity thermal cycle verification. This ensures that every shipment meeting export standards maintains complete unit consistency and long-term operating safety.
OEM/ODM Customization Flexibility: We support complete custom branding, tailored sheet-metal housing design, custom voltage configurations (12V, 24V, 48V, 51.2V up to 800V high-voltage stacks), custom BMS communication protocols (compatible with Deye, Victron, Growatt, SMA, Sofar, and Solis inverters), and customized eco-friendly packaging.
Adaptable storage architectures tailored to unique regional grid challenges, climatic extremes, and regulatory environments across the globe.
With rising grid demand charges and fluctuating spot-market electricity prices, Suntherra’s 200kWh - 500kWh liquid-cooled LiFePO4 systems allow enterprise facilities, EV charging stations, and manufacturing plants to store off-peak solar energy and discharge during peak demand hours, drastically lowering monthly operational expenses.
For island environments with unstable grid infrastructure and high humidity, Suntherra provides IP65-rated outdoor containerized systems and modular wall-mounted LiFePO4 units built with anti-corrosion marine-grade coatings to guarantee continuous clean power supply.
In high-temperature desert regions where diesel generator fuel costs are prohibitive, Suntherra’s OPzV tubular gel and high-temperature lithium batteries operate reliably up to 60°C, providing 24/7 backup power for mobile base stations and remote agricultural pump systems.
