Custom Lithium Battery Solutions for Dry-Wet Vacuums | OEM/ODM Support

1. Introduction

The cleaning equipment industry is rapidly transitioning toward cordless solutions,
offering enhanced portability, convenience, and energy efficiency.
Dry-wet vacuums, widely used in homes, commercial buildings, and industrial environments,
rely heavily on high-performance battery systems for strong suction, extended runtime, and consistent power delivery.

With over 26 years of experience in lithium battery development and manufacturing,
PKNERGY provides fully customized lithium battery packs tailored for wet-dry vacuum applications—helping R&D managers
build durable, safe, and market-ready cordless vacuum systems.

2. Application Background

Dry-wet vacuums require battery systems that meet the following performance needs:

• High power discharge to maintain suction stability during continuous operation
• Long runtime for extended cleaning tasks without recharging interruptions
• Lightweight and compact pack design to ensure user comfort
• Stable performance across wide temperature ranges and wet cleaning environments
• Strong protection against vibration, shocks, and potential liquid exposure

Key engineering challenges include thermal control during high-power discharge, integration of battery packs within compact housings,
ensuring IP-related safety in wet environments, and maintaining long cycle life.
Cost efficiency and certification compliance are also critical for global market deployment.
