48V 600Ah LiFePO4 Forklift Lithium Battery 4000 Cycle Life Counterbalance Truck Power
Product Overview
This 48V 600Ah LiFePO4 forklift lithium battery is engineered for counterbalance forklifts in the 2.5-3.5 ton class, delivering up to 4000 charge cycles at 80% depth of discharge (DOD). Compared with traditional lead-acid batteries that typically last only 1200-1500 cycles, this lithium iron phosphate power pack extends service life by 2.5-3 times, significantly reducing the total cost of ownership over the equipment lifecycle.
The battery adopts automotive-grade LiFePO4 prismatic cells with welded busbar connections, ensuring low internal resistance, excellent thermal stability and consistent voltage output under heavy lifting loads. It is designed as a true drop-in replacement, fitting standard 48V battery compartments without modification to the forklift or charger system.
Core Selling Point: Industry-Leading Cycle Life
Cycle life is the most critical parameter for forklift battery economics. Our 48V 600Ah LiFePO4 battery achieves 4000 cycles at 80% DOD, verified through accelerated aging tests following IEC 62660-1 standards. This translates to 8-10 years of service in single-shift operation, or 4-6 years in demanding multi-shift applications.
- 4000 cycles @ 80% DOD: 2.5-3x longer than lead-acid batteries
- Deep discharge capability: supports 100% DOD in emergency situations without permanent damage
- Low self-discharge rate: less than 3% per month, ideal for intermittent operation
- No memory effect: partial charging does not reduce usable capacity
- Consistent performance: voltage plateau maintains full lifting speed until the last 5% of capacity
Discharge Characteristics
| Discharge Rate | Capacity Retention | End Voltage | Max Duration |
|---|
| 0.5C (300A) | 100% | 45.6V | Continuous |
| 1C (600A) | 95% | 44.4V | Continuous |
| 1.5C (900A) | 90% | 42.0V | 30 min |
| 2C (1200A) | 85% | 40.8V | 3 seconds (peak) |
The wide discharge plateau between 2.8V and 3.2V per cell ensures the forklift maintains full hydraulic lifting speed and travel performance until the battery reaches 95% depth of discharge. Operators will not experience the "power fade" typical of lead-acid batteries in the final hours of a shift.

A: Yes. The FL-48V600Ah is designed as a drop-in replacement with matching dimensions and connectors. Our engineers will confirm compatibility based on your forklift model before shipment.
Q2: Do I need a new charger?
A: We recommend a LiFePO4-specific charger. If you have a compatible 48V lithium charger, it can be reused. Existing lead-acid chargers must not be used.
Q3: How long does the battery last per charge?
A: With 600Ah capacity and typical 2.5-3.5T forklift duty cycles, one charge supports 6-8 hours of continuous operation, or a full multi-shift schedule with opportunity charging.
Q4: Is the battery safe?
A: LiFePO4 chemistry is the safest lithium battery chemistry, with high thermal stability and no thermal runaway risk under normal operation. The battery is UN38.3 certified and fully protected by the smart BMS.
