ER26500 + SPC1520 High-Capacity Lithium Battery Pack

The ER26500 + SPC1520 Battery Pack is a high-capacity hybrid power module designed to support IoT sensors that need both long-term steady current and short, high-current bursts — such as LoRaWAN, 4G/NB-IoT sensors, GPS trackers, and industrial telemetry devices.

The ER26500 lithium-thionyl chloride (Li-SOCl₂) cell provides exceptional energy density and multi-year lifespan, while the SPC1520 supercapacitor delivers the instantaneous pulse current required for wireless transmissions, startup surges, and cold-temperature performance.

This combination is ideal for battery-powered field deployments where reliability, longevity, and maintenance-free operation are essential.

Australian Stocked & Supported by ProSense — compatible with ProSight and third-party IoT systems.
