DKH High-Voltage Energy Storage Lithium Battery
The product features a standardized stacking design, allowing free module expansion. It supports master-slave networking and high-voltage matching, with an integrated intelligent BMS for real-time cell monitoring, voltage balancing, and overcharge/over-discharge protection. Standard interfaces include RS485/RS232/CAN; optional WiFi/4G or Bluetooth remote monitoring enables seamless integration with energy storage inverters and cloud platforms. The DKH series uses a natural cooling structure for flexible installation in cabinets, racks, or stacked on the floor. With an IP20 rating, it offers strong environmental adaptability, operating stably from 0 to +40°C at altitudes up to 2500 meters. It delivers excellent cycle life, maintaining ≥80% capacity after 6000 cycles at 80% DOD. Fully customizable, parameters like charge/discharge current, voltage, capacity, and dimensions can be adjusted per requirements. Warranty periods range from 5 to 10 years. Certified under CE, ROHS, FCC, UN38.3, MSDS, and ISO9001, this reliable solution is widely used in factory energy storage, PV systems, telecom base station backups, data center UPS, and off-grid power in remote areas.

Key Product Advantages
Modular stackable design for flexible expansion: The DKH series features a stackable form factor where each module operates independently. Expanding capacity later requires only adding corresponding battery modules, eliminating the need to replace the entire energy storage system and reducing upgrade costs. It supports master-slave networking, with high-voltage output precisely matching mainstream energy storage inverter input requirements for maximum compatibility.
Smart BMS Management for Safe, Stable Operation: Each battery pack features a high-precision Battery Management System that monitors voltage and temperature of every cell in real time. It automatically balances cells and precisely controls charge/discharge thresholds to prevent overcharging, over-discharging, overcurrent, short circuits, and overheating—eliminating safety risks and significantly extending overall battery lifespan.
Expand Communication & Enable Smart O&M: Equipped with industrial-grade communication interfaces, it integrates seamlessly with energy storage monitoring platforms for remote access to voltage, capacity, charge/discharge status, and fault alerts. With optional wireless connectivity, technicians can troubleshoot equipment issues without visiting the site, reducing manual O&M costs.
Ultra-long cycle life with high ROI: Delivers 6000 charge-discharge cycles at a 80% depth of discharge and room temperature under 0.5C conditions, maintaining energy retention of at least 80% after cycling. Ideal for commercial and industrial PV storage scenarios requiring multiple daily cycles, it ensures stable operation for over a decade—far exceeding the lifespan of traditional lead-acid batteries.
Highly customizable solutions tailored to your unique projects: We can customize output voltage, capacity, charge/discharge current, casing color, and dimensions to meet your specific requirements. Ideal for overseas brand owners and system integrators building their own branded products.
Primary Use Cases:
Commercial & Industrial PV+Storage: Rooftop solar with battery storage for factories and retail spaces to arbitrage peak-valley electricity rates, flatten load profiles, and reduce energy costs.
UPS Backup Power: Ensures uninterrupted operation of critical equipment in data centers, communication base stations, medical devices, and precision instruments during power outages.
Off-grid microgrid power supply: Deploy independent power systems in remote mountainous areas, islands, and construction sites without grid access, paired with solar panels for self-generation and self-consumption.
Home or small villa high-voltage energy storage: Compatible with high-voltage inverters to build a home energy storage system, addressing power outages and electricity price fluctuations.
Energy Storage Project Integration: System integrators and engineering contractors procure battery modules to assemble large-scale energy storage cabinets and containers, installing internal battery units.
