703048 3.7V 2200mAh LiPo Battery

Product Overview

The 703048 2200mAh is a high-capacity variant of our proven low-temperature LiPo battery series, delivering 3.7V / 2200mAh in the same compact 7.0×30×48mm soft-pack form factor. Engineered with a proprietary low-temperature electrolyte system, this battery maintains over 80% capacity at -20°C and over 60% at -40°C — making it the ideal power solution for GPS trackers, cold chain monitoring systems, military-grade devices, and outdoor IoT terminals deployed in harsh winter environments. UN38.3 and IEC62133 certified for global shipping and compliance.

Key Specifications

Low-Temperature Performance Data

⚠️ Competitive Note: Standard LiPo batteries typically retain less than 30% capacity at -40°C (≈660mAh). The 703048 LT delivers 2× the cold-weather output of conventional cells at the same temperature.

Product Highlights

① 2200mAh — Double the Runtime vs Standard 703048 Compared to the 1100mAh standard version, this high-capacity variant provides twice the runtime in the same footprint — eliminating the need for battery pack expansion in space-constrained device designs.

② Extreme Cold Reliability to -40°C Low-temperature optimized electrolyte maintains stable ionic conductivity in sub-zero conditions, ensuring reliable device cold-start and sustained operation in Arctic, alpine, and cold storage environments where standard batteries shut down.

③ 100°C Total Operating Range With a -40°C to +60°C operating window, this battery handles year-round deployment across all climate zones — from Siberian winters to tropical summers — without seasonal battery replacement.

④ Optimized for Low-Power IoT Devices Flat discharge curve at low temperatures ensures stable voltage output for GPS modules, LoRa sensors, and NB-IoT terminals — preventing premature low-voltage shutdowns during extended field deployment.

FAQ

Q: How does the 2200mAh version achieve higher capacity in the same 703048 size? A: Higher capacity is achieved through advanced high-density electrode coating technology and optimized cell stacking, without compromising low-temperature electrolyte performance.

Q: Can this battery charge at -20°C? A: Charging below 0°C is possible but only recommended above -20°C at reduced current (0.1C) to prevent lithium plating. For charging in extreme cold, we recommend our self-heating battery module variant.

Q: Is this suitable for LoRa / NB-IoT devices with pulse current demands? A: Yes. The 703048-LT 2200mAh supports up to 1C (2200mA) pulse discharge, covering the peak current requirements of most LoRa and NB-IoT transmission bursts.

Q: Do you offer a self-heating version for below -40°C applications? A: Yes. We offer integrated self-heating LiPo modules for environments below -40°C with built-in heating film and thermal management circuit. Please contact us for specifications.
