Description

Functional Positioning and Target Users
This 36V 2900mAh 18650 battery pack is engineered as a stable mobile power source for outdoor equipment manufacturers, vehicle system integrators, GPS solution providers, IoT device developers, and field engineering teams. As a professional-grade rechargeable lithium ion battery, it is designed to support equipment that operates in demanding environmental conditions where temperature fluctuation, vibration, and long-duration discharge are unavoidable. Typical users include OEM system builders, integration engineers, and maintenance teams responsible for ensuring uninterrupted power supply in mobile or outdoor-installed devices. The battery pack is supplied as a ready-to-integrate energy module rather than a consumer battery, allowing direct installation into system enclosures, control cabinets, or vehicle-mounted power compartments.

Electrical Architecture and Core Performance Parameters
The battery pack is built using high-consistency 18650 li-ion lithium battery cells configured to achieve a nominal output of 36V with a rated capacity of 2900mAh. It is designed for continuous discharge stability and reliable peak current output to support GPS terminals, outdoor sensors, communication nodes, and intelligent control units. The operating temperature range of -40°C to 85°C ensures stable electrochemical performance under both extreme cold and high-heat working conditions. An integrated protection system manages overcharge, over-discharge, over-current, and short-circuit risks, safeguarding both the battery pack and connected equipment. Cell balancing technology maintains voltage consistency across all series connections to extend service life and operational safety.

Industry Application Value and System-Level Contribution
In mobile power systems, reliable energy delivery directly determines equipment uptime and system integrity. This lithium ion battery pack provides a standardized 36V power architecture that simplifies system power design for engineers across multiple industries. It eliminates the need for complex multi-battery series wiring on site and reduces failure points in outdoor installations. For OEM customers and system integrators, the pack supports rapid deployment, predictable electrical behavior, and reduced after-sales maintenance risk. Its wide temperature tolerance also enables deployment in high-altitude regions, cold-zone installations, and enclosed high-heat equipment housings without performance instability.
