703048 3.7V 2200mAh LiPo Battery
$2.50
703048 3.7V 2200mAh low-temperature LiPo battery, retains over 80% capacity at -20°C for GPS trackers, cold chain logistics monitors and outdoor IoT terminals.
The HNF-703048 is a high-capacity low-temperature lithium polymer battery delivering 2200mAh at 3.7V in a compact 7 x 30 x 48mm soft-pack format. Engineered with a proprietary cold-weather electrolyte, it retains over 80% capacity at -20℃ and over 60% at -40℃ — making it the preferred power source for GPS vehicle trackers, cold chain logistics monitors, outdoor IoT terminals, and military-grade devices deployed in Arctic or alpine environments. Compared to the standard 1100mAh version, this variant delivers double the runtime in the same footprint.
