How to Choose the Right LiFePO4 Battery Pack for Industrial Applications: A Complete Selection Guide

Industrial equipment is becoming more intelligent, automated, and energy-efficient. From electric forklifts and warehouse vehicles to AGV robots, AMR systems, cleaning machines, marine equipment, and energy storage systems, reliable power supply has become a key factor affecting productivity.

Traditional lead acid batteries have been widely used in industrial applications for many years. However, with increasing requirements for longer operating time, faster charging, lower maintenance, and improved safety, more companies are upgrading to LiFePO4 battery packs (Lithium Iron Phosphate Battery Packs).

Choosing the right LiFePO4 battery pack is not simply selecting a battery with a higher capacity. A suitable industrial lithium battery solution needs to consider:

• 電圧要件
• Battery capacity
• Discharge performance
• 動作環境
• バッテリー管理システム（BMS）
• 通信要件
• 安全認証
• Mechanical design
• Long-term operating costs

This guide explains how to select the right LiFePO4 battery pack for industrial applications.

1. Understand Your Application Requirements First

Before choosing a LiFePO4 battery pack, the first step is understanding how the battery will be used.

Different industrial applications have different power requirements.

例えば、こうだ：

A battery designed for a forklift may not be suitable for a small robot because the operating conditions and electrical requirements are different.

2. Select the Correct Battery Voltage

Voltage is one of the most important parameters when selecting a LiFePO4 battery pack.

Common industrial lithium battery voltages include:

• 12.8V LiFePO4 Battery
• 25.6V LiFePO4 Battery
• 38.4V LiFePO4 Battery
• 51.2V LiFePO4 Battery
• 72V LiFePO4 Battery

The battery voltage should match the equipment system.

3. Choose the Right Battery Capacity (Ah)

Battery capacity determines how long the equipment can operate.

Capacity is measured in:

Ah (Ampere-hour)

A higher Ah rating generally means:

• 稼働時間の延長

The required capacity depends on:

• Equipment power consumption
• Working hours per day
• Load conditions
• 充電頻度

例

A warehouse AGV operates:

• 8 hours per day
• Average current: 20A

必要な容量：

20A × 8 hours = 160Ah

A suitable battery design may consider:

48V 160Ah LiFePO4 battery pack.

4. Check Continuous and Peak Discharge Current

Industrial equipment often requires high power during startup or acceleration.

Therefore, battery selection should consider:

連続放電電流

The maximum current the battery can continuously provide.

ピーク放電電流

The short-term current output during:

• Motor startup
• Heavy loading
• 加速

例えば、こうだ：

A forklift may require higher peak current when lifting heavy loads.

A professional battery supplier should evaluate:

• モーター出力
• コントローラの仕様
• Maximum operating load

5. Choose the Right Battery Cell Type
