How Does a 51.2V 50Ah Rack-mounted LiFePO4 Battery Deliver Reliable Power?
A 51.2V 50Ah rack-mounted LiFePO4 battery delivers 2.56 kWh of efficient, reliable energy storage with a nominal voltage of 51.2V and capacity of 50Ah. Designed for critical infrastructure such as telecom, data centers, and renewable energy systems, it offers long cycle life, rapid charging, and enhanced safety, outperforming traditional lead-acid batteries.
What are the key specifications of a 51.2V 50Ah rack-mounted LiFePO4 battery?
This battery features a nominal voltage of 51.2V and a capacity of 50Ah, providing 2.56 kWh of energy. Typical dimensions are 484 x 410 x 88.5 mm (2U rack size) and it weighs approximately 26.5 kg. It supports continuous discharge currents of 50A and peak currents up to 100A for short bursts. The enclosure is powder-coated steel with an IP21 rating, upgradeable upon request. Communication interfaces include RS485, CAN bus, and RS232. The integrated Battery Management System (BMS) offers overcharge, over-discharge, short circuit, and temperature protections.
How long can a 51.2V 50Ah LiFePO4 battery power critical systems?
Depending on load, this battery can provide backup power for 1 to 4 hours. For example, at a continuous load of 25A, it can deliver approximately 2 hours of operation (50Ah ÷ 25A). Runtime varies with power consumption and system requirements.
What advantages do LiFePO4 batteries offer over traditional lead-acid batteries?
LiFePO4 batteries provide higher energy density, longer cycle life (over 4000 cycles at 60% depth of discharge), faster charging, and superior thermal stability. They are lighter, maintenance-free, safer, and provide consistent voltage output, reducing downtime and total cost of ownership.
How does the Battery Management System (BMS) enhance safety and performance?
The BMS continuously monitors voltage, current, temperature, and state of charge, preventing overcharge, over-discharge, overheating, and short circuits. It balances cell voltages to maximize battery life and triggers alarms or shutdowns if unsafe conditions occur.
What are the optimal charging and discharging parameters for these batteries?
Charging is recommended between 0°C and 45°C with a maximum continuous charge current of 25A. Discharging is effective from -20°C to 60°C, supporting continuous discharge currents of 50A and peak currents up to 100A for short bursts.
How long is the typical lifespan and cycle life of a 51.2V 50Ah rack-mounted LiFePO4 battery?
These batteries typically offer over 4000 cycles at 60% depth of discharge, translating to about 8 to 10 years of service life, significantly outperforming lead-acid batteries.
What applications are best suited for rack-mounted LiFePO4 batteries?
Ideal for telecom base stations, data centers, renewable energy storage, uninterruptible power supplies (UPS), and industrial backup systems, these batteries provide reliable, scalable power solutions.
What environmental conditions can a 51.2V 50Ah LiFePO4 battery withstand?
Designed for indoor rack-mounted use, these batteries operate reliably between -20°C and 60°C and feature an IP21-rated enclosure protecting against dust ingress.
How does rack-mounted design improve installation and maintenance?
Rack-mounted design optimizes space utilization, simplifies installation and maintenance, supports modular scalability, and ensures secure, organized battery management.
What communication protocols are integrated for monitoring and system integration?
Common protocols include RS485, CAN bus, and RS232, enabling real-time monitoring of voltage, current, temperature, and state of charge for remote diagnostics and predictive maintenance.
What certifications and safety standards do these batteries comply with?
These batteries comply with UL1973, IEC62619, UN38.3, CE, and RoHS certifications, ensuring safety, quality, and regulatory compliance.
