Custom Lithium Battery Solutions for Smart Security Cameras

Smart Security Camera Market Overview

In the rapidly expanding smart security market, the performance of battery-powered cameras has become a decisive factor for overall system reliability. From residential monitoring to enterprise-level outdoor deployments, manufacturers are increasingly shifting toward custom lithium-ion battery packs to achieve longer runtime, higher power stability, and improved device integration.

As a supplier specializing in cylindrical and prismatic lithium-ion pack customization, PKNERGY supports security camera manufacturers who need flexible, safe, and high-efficiency energy solutions tailored to the compact form factors of modern surveillance devices.

Why Smart Security Cameras Need Custom Battery Packs

Battery-powered cameras face constraints very different from conventional AC-powered systems. They must remain compact and lightweight while providing long operational hours, stable discharge curves, and compatibility with high-consumption components such as IR LEDs, LTE/4G modules, WiFi, PIR sensors, and motion-activated recording systems.

Standard off-the-shelf batteries often fail to meet these requirements due to limitations in dimensions, connectors, protection circuits, or environmental durability. Custom cylindrical (e.g., 18650 / 21700) and prismatic Li-ion pack configurations enable optimal performance without compromising device design.

Cylindrical Packs (18650 / 21700) for High-Power and Long Runtime

Smart outdoor cameras increasingly integrate AI detection, cloud streaming, and continuous monitoring features, all of which demand higher energy density and robust discharge capabilities. Cylindrical cells such as 18650 and 21700 offer key advantages:

• High energy density suitable for extended operation (weeks to months per charge)
• Stable continuous discharge for communication modules and IR night-vision functions
• Longer life cycles, critical for long-term deployment without frequent replacement
• Flexible pack configurations, such as 1S1P, 2S1P, or 2S2P, enabling different voltage and capacity ranges

PKNERGY’s cylindrical packs can integrate enhanced BMS functions, including overcharge, over-discharge, short-circuit and load-disconnect protections, ensuring safety even under heavy power bursts from IR lights or motion-triggered recording.

Prismatic Packs for Slim and Lightweight Camera Designs

For compact, aesthetic indoor cameras, prismatic Li-ion cells (such as 903048 / 103450 / 523450 formats) offer thinner structures and customizable dimensions. These packs are ideal for sleek home-security cameras that require:

• Low profile and reduced thickness
• Customizable geometries for housing integration
• Efficient power delivery for low-to-moderate consumption systems
• Optional soft-pack construction for maximum design flexibility

PKNERGY designs prismatic packs with JST / PH / XT connectors, optimized wiring layouts, and integrated protection circuits to ensure reliable standby performance, especially in low-duty-cycle monitoring applications.

Battery Performance Requirements for Smart Cameras

Modern smart cameras require batteries that can support:

• High pulse currents for wireless transmission and motion-triggered events
• Stable output voltage to avoid reboot or recording failure
• High charge retention for devices that may remain idle for days
• Compact size for small form-factor designs
• Wide operating temperature range for outdoor environments

PKNERGY collaborates closely with engineering teams to match battery pack specifications with device power curves, ensuring optimal alignment between consumption patterns and battery capacity.
