3.7V 7200mAh High Temp LiPo Battery Solution for Automotive T-Box & IoT
In the demanding environment of automotive IoT and telematics—such as Car T-Box systems—devices must operate continuously within confined spaces while maintaining reliability under extreme heat. Conventional consumer-grade LiPo batteries often fall short under these conditions, leading to reduced lifespan, unstable power output, and potential safety concerns.
To address these challenges, CMB has developed a high-temperature-resistant 3.7V 7200mAh high temperature lipo rechargeable battery, delivering stable power, superior thermal endurance, and long-term reliability.
Key features：
- Extended Thermal Tolerance: Supports discharge temperatures up to 80°C, maintaining stable performance in vehicle environments.
- Improved Capacity-to-Size Ratio. 7200mAh capacity achieved within a compact 35 × 55.5 × 68 mm footprint.
- Stable Power Output.Controlled charge and discharge currents ensure consistent voltage for communication modules.
- Balanced Charging Design. 0.72A standard charge current reduces thermal stress and extends service life.
