GRANKIA HV25K512 25.6kwh stackable lithium ion polymer battery 512V offers high charge/discharge efficiency, minimizing energy losses and maximizing the utility of stored energy.
Stackable Lithium ion Polymer Battery Features
High Voltage Operation
Operating at 512V, the lithium ion polymer battery reduces the need for complex voltage conversion equipment, providing a direct match for many high-voltage systems like solar inverters or grid-tied battery storage systems.
Long Cycle Life
Built with advanced LiFePO4 chemistry, this battery boasts an extended cycle life of over 6,000 cycles at 80% depth of discharge (DoD). This ensures years of reliable performance, reducing the need for frequent replacements and lowering overall costs.
Fast Charging Capability
The stacked lithium iron phosphate battery supports rapid charging, allowing for quick turnaround times between uses. This feature is particularly beneficial for applications requiring frequent cycling, such as electric vehicles and commercial energy storage systems.
Scalable and Modular Design
This battery’s modular design allows for easy stacking, enabling users to expand their energy storage capacity as needed. Multiple units can be combined to achieve desired energy levels, ranging from 10 kWh to 25 kWh by adding additional modules.
Advanced Battery Management System (BMS)
It is equipped with an intelligent BMS that monitors and manages cell voltage, current, temperature, and state of charge (SoC) in real-time. This ensures optimal performance, prevents overcharging or deep discharging, and extends the battery’s lifespan.
Integrated Communication Interfaces
The battery is equipped with RS485, CAN communication interfaces, enabling seamless integration with energy management systems (EMS), solar inverters, and monitoring platforms. This allows for real-time data tracking and remote control.
