The 48V 30Ah (15S5P) LIFEPO4 32650 LFP cell rechargeable battery is another member of the Lithium Iron Phosphate (LiFePO4) family, sharing many of the same characteristics as the 36V version you explored earlier. Here’s a breakdown of its key features:
Voltage and Capacity:
- Nominal Voltage: 48 Volts (V) – This is the standard operating voltage at which the battery delivers power.
- Capacity: 30 Ampere-hours (Ah) – This signifies the total amount of electrical charge the battery can store. Similar to the 36V battery, it represents the runtime the battery can provide at a specific current draw.
Cell Configuration (15S3P):
- 15S: Here, 15 cells are linked in series. This connection adds up the voltage of each cell. In this case, it becomes 15 cells * 3.2 V/cell (nominal voltage of a LiFePO4 cell) = 48 V. As with the 36V battery, slight variations might cause a voltage slightly above or below 48V.
- 5P: Similar to the 36V battery, 5 groups of cells are wired in parallel. This configuration increases the total capacity of the pack. Assuming each cell has a capacity of 6 Ah, the combined capacity becomes 5 groups * 6 Ah/group = 24 Ah.
Battery Chemistry: LiFePO4 32650 LFP cell (Lithium Iron Phosphate)
- Like its 36V counterpart, this battery leverages the advantages of LiFePO4 chemistry, known for:
- Safety: Exceptional stability and tolerance against misuse, reducing fire risks.
- Durability: Extended lifespan, typically lasting around 10-15 years or 2500 charge cycles.
- Lower Maintenance: Requires minimal maintenance compared to lead-acid batteries.
Applications:
Due to its higher voltage (48V) compared to the 36V battery, the 48V 30Ah LiFePO4 battery is suitable for applications demanding a bit more power. Here are some common uses:
- Electric Bikes (e-bikes) – Higher power e-bikes
- Electric Scooters
- Solar Energy Storage Systems
- Robotics
- UPS (Uninterruptible Power Supply) Systems
- Power Tools (some high-powered tools)
Additional Considerations:
- Weight: Even with the higher voltage, LiFePO4 batteries remain significantly lighter than lead-acid batteries of similar capacity.
- Battery Management System (BMS): Similar to the 36V battery, a BMS is likely integrated to safeguard the battery from over-charging, over-discharging, over-current draw, and overheating, ensuring its safety and lifespan.
In essence, the 48V 30Ah (15S5P) LiFePO4 battery offers a powerful and reliable option for various applications where extended lifespan, safety, and good power delivery are crucial. Always refer to the manufacturer’s specifications for specific details and ensure compatibility with your device before purchasing.
