Connected devices are only as reliable as the battery inside them. A smart meter that loses power, an asset tracker that goes dark, a sensor that misses a reading — each one breaks trust in the whole network. Leolus Energy builds custom lithium batteries for IoT and smart devices that hold up over years of always-on operation in the field.

As an Indian IoT battery manufacturer, we design packs around the real constraints of connected hardware: tiny form factors, ultra-low self-discharge for long standby, wide temperature tolerance for outdoor installs, and a BMS that protects the device through thousands of micro-cycles. Whether you're shipping smart meters by the thousand or prototyping a new tracker, we build to your spec.

IoT & Smart Devices We Power

Smart Meters

Long-standby lithium packs for electricity, water and gas smart meters that must run for years between service.

GPS Tracking Devices

Compact, high-density batteries for vehicle and personal GPS trackers needing long runtime in a small footprint.

Asset Tracking Solutions

Low self-discharge packs for logistics and asset trackers that sit idle then transmit on demand.

Smart Locks

Reliable batteries for smart locks and access devices where a dead battery means a locked-out user.

Smart Sensors & Data Loggers

Stable, long-life cells for environmental sensors and data loggers in remote or industrial settings.

Wireless & Remote Monitoring

Rugged packs for wireless monitoring and remote telemetry systems deployed outdoors.

Industrial IoT Devices

Battery solutions for Industrial IoT nodes that demand reliability in harsh plant environments.

Smart Agriculture Devices

Weather-tolerant batteries for soil, irrigation and farm IoT devices in the field.

IoT & Smart Device Batteries — FAQs

We manufacture custom lithium battery packs for smart meters, GPS and asset trackers, smart locks, sensors, data loggers and industrial IoT devices — sized for long standby, low self-discharge and wide temperature operation, each with an integrated BMS.

Yes. Long-standby IoT devices are a core use case. We select low self-discharge cells and tune the BMS for minimal quiescent drain, so devices like smart meters can run for years between replacements.
