Introduction
The global logistics industry increasingly relies on IoT-based freight and cargo trackers to monitor shipments, containers, and assets in real time. These compact devices combine GPS/GNSS positioning, NB-IoT or LTE-M communication, and motion or temperature sensors, ensuring that logistics operators always know where their goods are.
But powering these trackers presents a major challenge — they must operate continuously for months or even years, withstand temperature extremes, and deliver stable energy for high-current data transmissions. This is where PKNERGY’s advanced LiFePO₄ and NMC lithium battery solutions make the difference.
Market Trend & Technical Requirements
Freight and cargo trackers operate in complex outdoor and mobile environments. Their batteries must meet:
- Long operation time: 6 months to 5 years depending on reporting frequency.
- High energy density: compact size and lightweight.
- Strong pulse discharge: to power cellular/NB-IoT modules (up to 2–3A).
- Wide temperature tolerance: −30 °C to +70 °C.
- Safety and certifications: UN38.3 / IEC62133 / CE / UL.
Replacing batteries during global shipping is impractical — hence the focus on long-life, high-safety lithium systems.
Typical Battery Configurations
PKNERGY provides customized LiFePO₄ and NMC battery packs tailored for logistics tracking devices.
- LiFePO₄ (3.2V / 6.4V) – 32700 or 21700 cells, 6–20Ah capacity.
Excellent thermal stability, long cycle life (>2000 cycles), ideal for long-term cargo monitoring. - NMC (3.6V / 7.4V) – 18650 or 21700 compact packs, 3–10Ah capacity.
Higher energy density, lighter weight, suitable for portable GPS/NB-IoT trackers.
Both chemistries can integrate:
- Smart BMS (CAN / RS485 / UART).
- Temperature protection and overcurrent control.
- Optional IP67/IP68 waterproof casing.
Performance Comparison & Engineering Insights
| Feature | LiFePO₄ Battery | NMC Battery |
|---|---|---|
| Nominal Voltage | 3.2 V | 3.6 V |
| Energy Density | ⭐⭐☆ (Moderate) | ⭐⭐⭐⭐ (High) |
| Cycle Life | ⭐⭐⭐⭐⭐ (>2000 cycles) | ⭐⭐⭐ (800–1200 cycles) |
| Safety & Thermal Stability | ⭐⭐⭐⭐⭐ | ⭐⭐⭐☆ |

Engineering insight:
LiFePO₄ is best suited for long-term monitoring devices with lower replacement tolerance and outdoor exposure.
NMC is optimal for lightweight, space-limited trackers requiring higher energy per volume.
