24V / 36V / 48V LiFePO4 Battery Pack Design for Floor Scrubbers
Industrial floor cleaning machines require high-uptime, deep-cycle motive power. Discover how Chalongfly designs custom LiFePO4 battery packs tailored to the voltage surges, moisture protection, and smart BMS requirements of commercial floor sweepers and scrubbers.
The Shift to High-Efficiency Lithium in Cleaning Equipment
For decades, the commercial cleaning industry relied on flooded lead-acid batteries. However, as floor scrubbers evolve from mechanical tools into sensor-rich robotic and high-performance ride-on platforms, lead-acid has become a major bottleneck due to 8-hour charge times and heavy maintenance.
When designing a modern floor scrubber lithium battery, engineers must prioritize Energy Density, Dynamic Discharge (C-Rate), and Thermal Stability. Lithium Iron Phosphate (LiFePO4) is the industry standard for this, offering over 3,500 cycles and absolute safety.
By analyzing the peak current draw of drive, brush, and vacuum motors simultaneously, Chalongfly customizes the internal BMS to prevent false overcurrent shutdowns during high-torque cleaning operations on Inclined ramps or heavily soiled warehouse floors.
Matching Voltage Architecture to Machine Size
The core of any motive power battery design is aligning the voltage system with the equipment's motor controller. As a leading OEM/ODM battery manufacturer, Chalongfly engineers battery packs based on three primary architectures:
24V Systems (25.6V Nominal)
Target: Walk-behind scrubbers and compact commercial cleaning robots.
Design: These 50Ah to 150Ah packs focus on weight reduction and space efficiency to ensure manually operated machines remain agile.
36V Systems (38.4V Nominal)
Target: Mid-sized ride-on scrubbers used in large retail and industrial spaces.
Design: Operating at 36V provides higher motor efficiency with lower current draw. Capacities usually range from 100Ah to 200Ah.
48V Systems (51.2V Nominal)
Target: Heavy-duty industrial ride-on scrubbers and street sweepers.
Design: Built for maximum torque. These packs often feature capacities from 200Ah to 400Ah+, using an architecture similar to our aerial work platform batteries.
5-Year Total Cost of Ownership (TCO) Comparison
For fleet operators, the transition to lithium is a financial decision. While LiFePO4 requires higher initial CapEx, the reduction in OpEx (labor, energy, and replacements) delivers a positive ROI within 18 months.
Direct Savings Result:
Switching from Lead-Acid to Chalongfly LiFePO4 reduces the 5-Year Total Cost of Ownership by up to 45% per machine.
| Performance Metric | Traditional Lead-Acid / AGM | Chalongfly OEM LiFePO4 |
|---|---|---|
| Cycle Life (100% DOD) | 300 - 500 Cycles | 3,500+ Cycles |
| Daily Maintenance | Watering & Acid Cleaning | Zero Maintenance |
| Charge Efficiency | 75% (8-10 Hours) | 95% (Fast Charge in 2H) |
| Opportunity Charging | Strictly Prohibited | Fully Supported |
Engineering for Harsh Cleaning Environments
Floor scrubbers operate in wet, chemically active, and high-vibration environments. A standard lithium pack will fail prematurely under these conditions.
IP67 Moisture Protection
Floor scrubbers deal with splashes and overflowing solution tanks. We design custom enclosures with IP67-rated seals and waterproof communication ports to prevent internal corrosion.
Custom Ballast Engineering
Walk-behind scrubbers rely on battery weight for brush pressure. To compensate for lithium's lightness, we engineer custom steel enclosures with integrated ballasts to match the original machine's center of gravity.
Shock-Proof Busbars (5G)
Scrubbers bounce over warehouse concrete joints. We utilize laser-welded pure copper busbars and EVA foam buffers between cell clusters to handle sustained mechanical impact.
Smart Harness Integration
A battery is only as good as its delivery system. We design custom wire harnesses using heavy-duty AWG cables and Anderson/REMA connectors for true plug-and-play assembly.

Frequently Asked Questions
Absolutely. A single 24V (25.6V nominal) LiFePO4 battery pack is the ideal replacement for four 6V lead-acid batteries wired in series. It fits perfectly within the existing battery tray and simplifies the wiring to just two main terminals.
LiFePO4 batteries allow for 100% Depth of Discharge (DOD) without damage, whereas lead-acid is limited to 50%. A 100Ah lithium battery provides effectively the same runtime as a 200Ah lead-acid battery but with 70% less weight.
In walk-behind machines, yes. To counteract this, Chalongfly designs custom battery cases with integrated steel ballasts to maintain the original downward brush pressure and machine traction.
Yes. Our BMS platforms support CANBus (J1939/CANOpen) or RS485 communication, allowing the battery to send real-time State of Charge (SOC) and health diagnostics directly to your dashboard.
