Is Lead-to-Lithium Conversion Feasible? MaxLi Solution Tackles 3 Pain Points with 60% Cost Reduction Verified

Still troubled by short battery life and frequent replacements? Do traditional lead-acid batteries burden your operation with inefficiency and environmental concerns? As lithium batteries rapidly replace lead-acid across the energy landscape, “Lead-to-Lithium” conversion is no longer optional — it’s essential for upgrading performance and reducing costs.

What Is Lead-to-Lithium Conversion?

“Lead-to-Lithium” refers to replacing the original lead-acid battery system of equipment with a lithium battery system through customized engineering. It’s not a simple battery swap—it involves reconfiguring the entire power architecture to ensure stable and efficient lithium battery operation. This process is widely applied across electric floor scrubbers, forklifts, boats, golf carts, AGVs, logistics vehicles, sightseeing vehicles, sanitation vehicles, and UPS systems.

Lead-Acid vs Lithium Battery: Performance Comparison

Step-by-Step Guide to Conversion

1. Needs Assessment & Battery Selection Evaluate the device's power demand (voltage, current, runtime) to select an appropriate lithium battery model.
2. Battery Compartment Modifications (if needed) Adjustments may be required to accommodate differences in battery size or mounting.
3. Charging System Upgrade Lithium batteries require dedicated chargers; original lead-acid chargers are incompatible.
4. Battery Installation Disconnect power supply and observe all safety protocols before installation.
5. BMS Calibration & Configuration Calibrate the Battery Management System to recognize and manage the lithium battery.
6. Testing & Commissioning Conduct full system tests; stop and troubleshoot if abnormalities occur until performance is stable.

Key Considerations During Conversion

• Safety First: Prevent short circuits, overcharging, or deep discharging.
• System Compatibility: Ensure both electrical and mechanical compatibility.
• Component Quality: Use certified lithium batteries and components only.
• Legal Compliance: Check regulations on battery modifications in your local region.

Main Challenges of Lead-to-Lithium Projects

• System Integration: Integrating lithium batteries requires holistic redesign of power architecture.
• Cost Control: Balancing cost, quality, and performance is crucial during system reengineering.
• Technical Knowledge: Requires knowledge across battery chemistry, power electronics, and automation systems.

Real Case: MaxLi Powers Forklift Fleet Upgrade

Project Background

A large logistics enterprise operated a sizable electric forklift fleet powered by lead-acid batteries. With rising business demand, issues like long charge times, short runtime, and frequent battery replacement began impacting operations. The company partnered with MaxLi for a full lithium upgrade.

Conversion Process

Step 1: Requirement Evaluation

MaxLi’s engineering team assessed the forklift usage, load, working hours, and environment. A tailored solution using high-energy-density LiFePO₄ batteries was proposed.

Step 2: Battery Production

Custom battery packs were manufactured under strict QC, with cell consistency ensured via 100% inspection.

Step 3: On-Site Installation & Commissioning

Old lead-acid batteries were removed; new lithium battery packs were installed and integrated. The charging system and control software were upgraded for compatibility. Comprehensive testing followed, including:

• Charging behavior & communication test
• Load simulation for runtime validation
• Functional tests (startup, acceleration, slope performance)

Each forklift was fine-tuned for optimal output.

Results

Economic Impact: Payback period <14 months; 60% lifetime cost savings.

Conclusion

Converting from lead-acid to lithium is a proven path to improving energy efficiency, runtime, and sustainability. Success depends on professional system design, quality components, and experienced service providers.
