Protection for system integration
Overcharge, over-discharge, over-current and short-circuit protection are part of the stated pack architecture.
Power for exposed operating environments
Wide-Temperature Battery Packs for Field Devices
This 3.6V 18650 battery platform is built around a 2900mAh nominal capacity, a broad discharge temperature range and project-level integration choices. For teams sourcing custom lithium battery packs or comparing a wholesale lithium ion battery pack, the fit depends on the device architecture, temperature envelope and wiring plan.

Cell balancing
Balancing helps keep series-connected cells aligned during operation and supports consistent pack behavior.
Temperature envelope
Separate charging, discharging and storage conditions
A wide operating range is useful only when the electrical limits and storage plan are reviewed together.
-40°C to 85°C is the discharge range for the battery pack.
At -40°C, the cell is designed to release more than 70% capacity at a 0.2C discharge rate.
Charging is listed from -20°C to 60°C, with different current limits across the lower temperature bands.
Storage guidance varies from -20°C to 25°C for up to 12 months through -40°C to 80°C within 30 days.
Integration inputs
Five details to settle before the pack is specified
These inputs turn a general battery request into a usable system conversation.
Confirm the device's nominal input and any peak-voltage behavior.
Match 2900mAh nominal capacity to the expected duty cycle and replacement plan.
Share connector type, cable length and routing constraints for the enclosure.
Describe the available space, vibration exposure and environmental protection needs.
Review protection, balancing and current limits with the system's controller.
Field-device fit
Where a wide-temperature pack earns its place
Use the application context to decide whether the pack's temperature and current envelope matches the deployment.
Outdoor monitoring
Weather stations, security sensors and remote data platforms can use the wide-temperature range where field replacement is difficult.
Vehicle-mounted systems
Vehicle terminals, GPS units, communication systems and transport monitoring devices benefit from a defined 36V power architecture.
IoT and edge nodes
Outdoor gateways, networking equipment and remote control units can be matched to the pack's discharge and integration limits.
