Rack lithium batteries with peak discharge capabilities provide short-term high-current bursts, while continuous current ratings support sustained energy output. These batteries are essential for data centers, telecom systems, and solar storage where both stability and high performance are critical. Redway Battery offers OEM rack solutions designed to meet these demanding peak and continuous specifications for reliable operation.

What Defines Peak and Continuous Discharge?

Peak discharge refers to the maximum current a battery can supply for a brief period, typically 2-5 times its continuous rating for a few seconds. Continuous discharge is the current a battery can maintain over hours without overheating. These ratings protect the battery from damage while ensuring the system receives appropriate power.

Rack lithium batteries commonly operate in 48V or 51.2V configurations. Peak currents can reach 200-500A, while continuous ratings are around 100A. Redway Battery designs LiFePO4 cells to exceed these standards with integrated BMS safety features.

How Do These Ratings Impact Performance?

Peak and continuous ratings determine whether a battery can handle sudden spikes in load and maintain reliable energy delivery. High peak ratings support short-term surges, while continuous ratings ensure long-term uptime. Misalignment can lead to voltage drops or system failure.

For example, a 5kWh rack battery may have 100A continuous and 300A peak ratings. Redway Battery tests these via C-rate cycles to ensure 6000+ cycles. OEM customization allows ratings to match solar or telecom rack requirements, reducing downtime by up to 50%. Temperature variations affect output, and Redway’s advanced cooling systems maintain consistent performance.

Why Choose Rack Lithium Over Lead-Acid?

Lithium rack batteries provide higher energy density, longer cycle life, and consistent peak/continuous performance compared with lead-acid alternatives.

• Depth of discharge up to 90%

• Faster charging rates

• Lighter weight for easier installation

Redway’s 100,000 ft² production facilities ensure scalable, high-quality solutions for OEM clients.

What Factors Influence These Ratings?

Battery performance depends on cell chemistry, C-rate, and battery management system design. LiFePO4 cells can safely handle 3C peak currents. Temperature swings can reduce continuous output by up to 30%, while high-quality cells and effective cooling mitigate this.

Key influencers:

• Internal resistance (lower resistance enables higher peaks)

• Thermal management systems

• Series-parallel configuration balance

Redway Battery leverages MES systems to monitor production, ensuring uniform and reliable ratings across all rack packs.

Which Specifications Should Buyers Prioritize?

Prioritize maximum continuous current, peak current, and depth of discharge. For 19-inch racks, 51.2V/100Ah batteries with 100A continuous and 250A peak ratings are recommended. Redway Battery can customize these specifications, including CAN bus integration for advanced monitoring.

How to Select the Right Rated Battery?

Selection involves matching battery ratings to load profiles. Continuous current should cover baseloads, while peak ratings address short-term spikes. Calculation of peak demand, continuous capacity, and redundancy ensures reliability.

Steps:

1. Calculate maximum peak demand

2. Determine required continuous capacity

3. Incorporate redundancy for uptime

Redway Battery provides full OEM/ODM customization, testing prototypes to match client specifications and reduce costs by 30% through direct factory supply.
