- Long Cycle Life: These batteries can endure more than 2000 charge cycles, significantly outlasting traditional lead-acid batteries.
- High Efficiency: They offer excellent charge and discharge efficiency, typically around 90% or higher.
Key Features Overview
| Feature | Description |
|---|---|
| Safety | Lower risk of thermal runaway |
| Long Cycle Life | Over 2000 cycles |
| High Efficiency | Charge/discharge efficiency >90% |
How Does LiFePO4 Compare to Other Lithium Batteries?
When compared to other lithium batteries like lithium-ion or lithium polymer:
- Thermal Stability: LiFePO4 is known for its superior thermal stability.
- Energy Density: While they may have lower energy density than lithium-ion batteries, their safety and longevity make them favorable for many applications.
- Cost Efficiency: Although they have a higher initial cost, their long lifespan often results in lower total cost of ownership.
Comparison Overview
| Feature | LiFePO4 | Lithium-Ion |
|---|---|---|
| Thermal Stability | High | Moderate |
| Energy Density | Lower | Higher |
| Cost Efficiency | Long-term savings | Shorter lifespan |
What Is the Cost Range for LiFePO4 Batteries?
The cost range for LiFePO4 batteries varies based on several factors:
- Smaller capacities (e.g., 12V 100Ah) generally cost around $500.
- Larger systems (e.g., 48V 200Ah) can exceed $2,000, depending on brand and features.
- Prices can fluctuate based on market demand and material costs.
Cost Overview
| Capacity (Ah) | Average Price Range |
|---|---|
| 12V 100Ah | $500 – $800 |
| 24V 200Ah | $800 – $1,200 |
| 48V 300Ah | $1,500 – $3,000 |
