Currently on the market, more and more people are showing great interest in server rack batteries when powering their homes or businesses, Lithium battery manufacturers are launching server rack battery products one after another, with the wide range of rack batteries, but how to differentiate them? This article will talk about the complete guide of server rack batteries, hopefully it can give enough reference for lithium battery distributors and users.

What is a server rack battery?

Server rack batteries have the same specifications as the network server room chassis, so they can be placed in the standard server racks in the data centre, usually also known as rack batteries, the common general size of the 3U or 4U height of the majority of the 1U and 2U less, the standard 19-inch chassis. Server rack batteries are compactly designed to fit 48V (51.2V) 100Ah rack batteries in a 1U-4U space with integrated built-in BMS, circuit breakers and other components.

Pros and Cons of Server Rack Batteries

Server rack batteries were originally used in data centres as an uninterruptible power supply (UPS) to provide back-up power to servers in the event of a power outage. They are a safety net to ensure your digital operations run smoothly, preventing downtime and potential data loss.

So what are the pros and cons of server rack batteries?

Advantage of Server Rack Batteries

Small size: Server rack batteries are available in sizes from 1U to 4U depending on capacity, with a standard 19-inch rackmount width for a clean look and easy installation.

Easy to use: plug and play.

Safety: metal casing, lithium iron phosphate A-grade batteries, safety, long life.

Serial and parallel support: support up to 16-way parallel connection to meet the demand of high-power consumption.

Intelligent communication interface: standard CAN, RS485, Bluetooth communication interface, you can mobile remote online debugging and monitoring of power system operation, you can view the voltage of each battery, SOC, and the overall voltage and current, to simplify the network management work, and improve the reliability of the system.

Disadvantages of server rack batteries

Not portable: 48V 100Ah server rack batteries can weigh up to 50kg; you have to use tools to move it.

Not Easy to Repair: When the battery is faulty, it is difficult to repair and needs to be replaced; for 48V batteries, there are usually 16 or 32 cells inside.

Server Rack Battery Price

The price of server rack batteries depends on the product&#;s cells, capacity, communication features, quantity, etc. Of course, there are also some other factors, such as increased warranty years, shipping, etc.

How to choose the server rack batteries you need

• Voltage and Capacity
• Charge/discharge multiplier
• Depth of Discharge (DoD%)
• Service Life, Warranty
• Expandability
• Installation
• Other

Voltage and Capacity

The capacity of a battery is the total amount of power it can store, measured in kilowatt-hours (kWh) or amp-hours (Ah). If the battery capacity is measured in Ah, simply multiply the battery voltage by the Ah rating:

Wh = Ah * V

Using a 48V 100Ah server rack battery as an example, 48V * 100Ah = Wh = 4.8Kwh.

Charge and Discharge Ratio

Capacity is how big a battery is, while charge/discharge multiplier is how much power a battery can deliver at a given moment, or how fast a battery charges and discharges.

Depth of Discharge

The Depth of Discharge (DOD) of a battery is the amount of capacity the battery has been used. Most battery manufacturers specify a maximum DOD for optimum performance. For example, if a 10 kWh battery has a maximum DoD of 90%, the battery should be no more than 9 kWh before charging.

Theoretically, all lithium batteries can be 100% discharged, but this will shorten their cycle life and may affect the warranty.

Useful Life and Warranty

In general, most lithium batteries have a life expectancy of 8 to 16 years. In most home solar systems, your batteries are &#;cycled&#; (charged and discharged) every day. Over time, the capacity of the battery decreases.

This is similar to the battery in a mobile &#; you charge your every night and the life of the battery diminishes. Extreme temperatures can also affect battery life.

Your lithium battery will have a warranty that guarantees a certain number of cycles or life, usually within a certain maximum DOD. For example, the warranty will usually state that the &#;maximum (or average) DOD is 80% for 10 years&#; and that &#;60% of the battery capacity&#; will be retained after 10 years.

Expandability

Most lithium batteries on the market today are designed to be &#;expandable&#;, which means you can connect multiple batteries in series and parallel to your solar system for additional capacity. Check this option to make sure you can expand the capacity in the future.

Installation

Nowadays, some batteries for home backup can be hung on the wall, such as LYBESS 48V Wall Mounted Home Battery, 5Kwh Powerwall Home Battery; some must be placed on the ground, such as High Voltage Stacking Series Batteries; and sometimes you will need to purchase specific cabinets, such as 48V Server Rack Batteries.

Other

There are some important factors to consider when choosing the right server rackmount battery for your needs. You also have to need to understand some of the types of safety certifications. The battery management system (BMS) plays a vital role in the safe use of the battery pack and provides maximum protection to the cells. It provides overcharge protection, overdischarge protection, short circuit protection, temperature protection, and cell balancing.
