The Raymond Walkie Stacker OPC-30TT originally comes with a 36V 625Ah lead-acid battery, with a battery compartment size of 967.5mm x 339.4mm x 776.7mm and a weight of 816.5kg (1800 lbs). The battery capacity of the original lead-acid setup is 22.5 kWh. Upon upgrading to a 36V 500Ah lithium-ion battery, the new battery’s weight is reduced significantly to 200kg. The new lithium-ion battery fits within the same compartment dimensions as the original lead-acid battery, and additional counterweight will be required to maintain proper forklift balance.

Product Specifications:

  • Weight: 200kg

  • Capacity: Equivalent energy storage but with increased efficiency.

  • Charging Time: Faster charging cycles compared to lead-acid batteries.

  • Maintenance: Minimal maintenance, no need for water refills, and no regular cleaning required.

Battery Discharge Efficiency Comparison:

When comparing lead-acid to lithium-ion batteries, the performance drop-off during discharge varies significantly. The graph below illustrates the discharge curves for both lead-acid and lithium-ion batteries, highlighting the differences in efficiency as the battery discharges:

• Lead-Acid Battery (AC Drive and DC Drive):
  As the battery discharges, the lead-acid battery’s performance rapidly declines, especially past the 50% discharge mark. The efficiency and power output of the battery fall sharply as it nears depletion, requiring frequent recharging.

• Lithium-Ion Battery (AC Drive):
  The lithium-ion battery, on the other hand, maintains a much more stable and consistent discharge rate. The performance remains strong over a larger portion of the discharge cycle, reducing the frequency of recharge needs and improving the forklift’s overall operational time.

This difference in discharge efficiency translates directly to reduced downtime, fewer recharging cycles, and a more consistent operational capacity, making the lithium-ion battery a superior choice for continuous, efficient use in Raymond Walkie Stacker OPC-30TT forklifts.

In summary, upgrading to a 36V 500Ah lithium-ion battery provides Raymond Walkie Stacker OPC-30TT with improved efficiency, faster charging, and lower maintenance costs, along with extended operational hours between charges.
