Redway Battery’s rack lithium batteries excel in parallel setups, supporting configurations of up to 16 units for high-reliability applications.

How Do Rack Lithium Batteries Work?

Rack lithium batteries use LiFePO4 cells integrated with a BMS to monitor voltage, current, temperature, and state of charge. During charging, the BMS balances the cells, and during discharge, the system ensures the voltage stays within safe limits by activating load detection.

The BMS also protects the battery from overvoltage, undervoltage, and excessive temperatures through MOSFET control. Additionally, parallel operation links the battery packs together via RS485 communication for synchronized performance, ensuring the system operates efficiently and safely.

How to Install Rack Lithium Batteries?

To install rack lithium batteries, mount them in standard 19-inch racks using lifting equipment for heavier units and secure them with screws. Connect the positive and negative terminals from the first and last units in the parallel strings, and use RJ45 connectors for RS485 or CAN communication with the inverters.

Ensure proper setup of dial switches for master-slave configuration and verify the polarity of connections. Redway Battery provides detailed installation guides to ensure a safe and efficient setup, tailored to your specific requirements.

What Safety Features Do They Have?

Rack lithium batteries come with a range of built-in safety features, including a robust BMS that offers protection against overcharge, over-discharge, overcurrent, short circuits, and temperature extremes. The active balancing mechanism ensures the health and longevity of the battery cells.

Additionally, the batteries are housed in flame-retardant casings with an IP20 rating, providing reliable safety during operation. Redway Battery’s commitment to safety is reflected in their adherence to ISO standards, and their battery packs meet UN38.3 shipping compliance for safe transportation worldwide.

Why Choose LiFePO4 for Rack Batteries?

LiFePO4 batteries are a preferred choice for rack applications due to their exceptional safety, long lifespan, and high efficiency. Unlike other chemistries like lead-acid, LiFePO4 batteries do not experience thermal runaway, and they offer more than 6000 charge cycles at 100% DOD, significantly outperforming lead-acid batteries that typically last for only 1000 cycles.

LiFePO4 also allows for higher discharge rates, making it suitable for high-demand solar peak times. Cost-per-cycle for LiFePO4 batteries reduces by up to 60% over the long term, offering excellent value for users. Redway Battery specializes in providing cost-effective and reliable LiFePO4 rack batteries, making them an ideal choice for large-scale energy storage solutions.

How to Maintain Rack Lithium Batteries?

For optimal performance, store rack lithium batteries at 50% State of Charge (SOC) in a temperature range of -10°C to 45°C. Charge the batteries monthly if they are not in use, and monitor the battery health using RS485 communication or app-based monitoring for alarms.

It is also essential to clean battery terminals regularly and avoid deep discharges below 20V. With proper maintenance, these batteries can last for more than 10 years, providing a long-term and cost-effective energy solution.

What Are Common Applications?

Rack lithium batteries are versatile and can be used in a variety of applications, including solar energy storage systems, UPS backups, telecom base stations, electric vehicles, and data centers. They offer a lighter, more efficient alternative to lead-acid batteries, and they require zero maintenance.

Redway Battery manufactures and supplies LiFePO4 rack batteries for a wide range of industries, including forklifts, golf carts, RVs, and energy systems, serving clients around the world with customizable and scalable solutions.
