EVE ES-261520/W | 3.6V 8500mAh Li-SOCl₂ Replacement Battery for Dragino Sensors

The EVE ES-261520/W is a 3.6V, 8500mAh Li-SOCl₂ (lithium thionyl chloride) replacement battery engineered to restore long-term power to Dragino LoRaWAN and NB-IoT sensors. It pairs an ER26500 cell with an SPC1520 supercapacitor to deliver the high pulse currents required for long-range transmissions while eliminating voltage delay. Supplied with a pre-fitted JST XH2.54 connector, it is a true plug-and-play replacement for the LSN50v2, LDDS75, RS485-LB and other Dragino nodes. Core Capabilities High-Capacity Reserve 8500mAh cell built for multi-year sensor deployments. Pulse-Ready Design SPC1520 capacitor supports 2A LoRa transmit peaks. Ultra-Low Self-Discharge Under 1% capacity loss per year at 25°C. Plug-and-Play Fit Pre-wired JST XH2.54 connector for Dragino boards. Industrial Applications • Smart Metering & Utilities: Repower RS485-LB converters and remote telemetry nodes. • Environmental Monitoring: Extend LSN50v2 and LSE01 sensor uptime in the field. • Level & Distance Sensing: Keep LDDS75 and LDDS20 level monitors running for years. Technical Integration The non-rechargeable ES-261520/W pack (ER26500 + SPC1520) measures 50 × 26mm, weighs 62g and supports 130mA continuous and 2A pulse discharge. Replacement is recommended once voltage drops below 2.7V. Compatible with Dragino LSN50v2, LSN50v2-D20, LSN50v2-S31, LDDS75, LDDS20, LSE01, NBSN95 and RS485-LB.
