How to Choose the Right Lithium Battery for an Aerial Work Platform (AWP)

As the aerial work platform (AWP) industry continues to shift from lead-acid batteries to lithium technology, choosing the right battery is becoming increasingly important.

A lithium battery is not simply a replacement for a lead-acid battery. It should be carefully matched to the machine's working conditions, electrical system, and safety requirements. An unsuitable battery may reduce productivity, shorten service life, or even create safety risks.

This guide explains the four key factors to consider when selecting a lithium battery for scissor lifts, boom lifts, and other aerial work platforms.

Different aerial work platforms have different power requirements.

Scissor Lifts

Stable working loads

Lower peak power demand

Suitable for standard LiFePO4 battery systems

Boom Lifts

Frequent lifting and telescoping movements

Higher peak current demand

Require batteries capable of higher discharge rates

Selecting the battery according to the machine's power profile helps maximize performance and battery life.

Environmental temperature has a significant impact on battery performance.

Below -20°C: Low-temperature LiFePO4 or specially designed NMC cells are recommended.

Above 50°C: Battery packs should include an active thermal management system to prevent overheating.

Battery capacity should be calculated based on:

Daily operating hours × Average motor power

To avoid unexpected downtime, it is recommended to reserve at least 20% capacity margin beyond the calculated energy requirement.

For most aerial work platforms, LiFePO4 (LFP) remains the preferred chemistry.

Its advantages include:

Excellent thermal stability

Long cycle life (typically over 3,000 cycles)

High safety

Suitable for dusty and humid construction environments

Lower maintenance costs

For extremely cold operating environments, NMC batteries may offer better low-temperature performance. However, they should always be equipped with an advanced Battery Management System (BMS) and appropriate thermal management.

Consumer-grade lithium batteries should never be used in industrial aerial work platforms because they cannot meet the required safety, durability, and protection standards.

A replacement lithium battery must match the original equipment specifications.

The battery voltage must be identical to the machine's electrical system.

Common voltages include:

24V

48V

72V

Changing system voltage without redesigning the vehicle is not recommended.

Battery capacity should satisfy a full working shift while maintaining approximately 20% reserve capacity.

Peak discharge current should exceed the machine's maximum demand.

For example:

A boom lift requiring 15 kW peak power should typically use a battery capable of at least 3C continuous/high-rate discharge, depending on system voltage and motor characteristics.

Construction environments expose batteries to:

Water

Dust

Mud

Vibration

Therefore, industrial battery packs should provide at least:

IP67 protection

Robust mechanical enclosure

Shock and vibration resistance

For hazardous industrial environments such as chemical plants or oil & gas facilities, explosion-proof certified battery systems may also be required.

If multiple battery packs are connected in parallel, they should have:

identical model

identical capacity

identical State of Charge (SOC)

This helps prevent imbalance and extends battery life.

The battery supplier is just as important as the battery itself.

A qualified industrial battery should include:

The BMS should provide:

Overcharge protection

Over-discharge protection

Over-current protection

Short-circuit protection

Temperature protection

Accurate SOC estimation

These functions improve both safety and operating efficiency.

Choose suppliers that can provide relevant certifications and testing reports, such as:

CE

UL

UN38.3

IEC 62619 (where applicable)

Third-party laboratory test reports

Certification requirements vary depending on the destination market and application.

Industrial equipment requires professional support throughout the product lifecycle.

Look for suppliers that offer:

Customized battery design

Vehicle integration support

Installation guidance

Remote technical assistance

Fast after-sales response

Long-term warranty

Installation should always be performed by qualified technicians. Unauthorized modification of the vehicle's electrical system may affect both safety and warranty.

Choosing the right lithium battery for an aerial work platform involves much more than selecting voltage and capacity.

Machine type, operating environment, battery chemistry, compatibility, safety, and supplier support all play critical roles in achieving reliable performance.

Working with an experienced lithium battery manufacturer helps ensure longer runtime, improved safety, reduced maintenance costs, and a lower total cost of ownership.
