Counterbalance Forklift 3.5-4T |
This 72V 600Ah LiFePO4 lithium battery is built for 3.5-4 ton counterbalance forklifts, providing 3500 charge cycles at 80% DOD and a leak-proof IP54 design. Intelligent CAN bus communication keeps the forklift controller continuously informed of battery status, ensuring optimal performance and enabling predictive maintenance.
Switching from lead-acid to this lithium pack eliminates battery change-out shifts, acid handling and watering tasks. With 1-2 hour fast charging, one battery can support multi-shift operations that previously required two or three lead-acid units plus a spare.
The 72V 600Ah pack delivers 3500 cycles at 80% DOD - roughly 8 years in single-shift service. Combined with CAN bus communication, fleet managers get real-time visibility into battery health, usage patterns and remaining capacity, allowing proactive scheduling and maximum asset utilization.
| Discharge Rate | Capacity Retention | End Voltage | Max Duration |
|---|---|---|---|
| 0.5C (300A) | 100% | 68.4V | Continuous |
| 1C (600A) | 95% | 66.6V | Continuous |
| 1.5C (900A) | 90% | 63.0V | 30 min |
| 2C (1200A) | 85% | 61.2V | 3 seconds (peak) |
The wide operating voltage window keeps the forklift hydraulic system at full pressure for consistent lifting of rated loads, even during peak current draws at high stacking heights.

Q1: How many lead-acid batteries does one lithium pack replace?
A: In multi-shift operations, one 72V 600Ah lithium battery with opportunity charging typically replaces two to three lead-acid batteries plus their change-out infrastructure.
Q2: Can the CAN bus connect to my forklift display?
A: Yes. We pre-configure the CAN protocol to match your forklift brand (Toyota, Linde, STILL, Jungheinrich, Hangcha, Heli, etc.) before shipment.
Q3: What happens in a cold warehouse?
A: LiFePO4 retains high efficiency at low temperature. Optional heating pads maintain optimal operating temperature in freezers down to -30 degrees C.
Q4: What warranty support do you provide?
A: 3-year warranty with technical support by email, phone and video. Spare parts and replacement cells are available globally.
