Product overview

VTC18650-5S1P 18V 3000mAh Lithium-Ion Battery Pack for industrial sensors, portable instruments, outdoor enclosures | Battery Manufacturers in China & Battery Supply Factory

The VTC18650-5S1P 18V 3000mAh 18650 Li-ion battery pack is built with cylindrical lithium-ion rechargeable cells in a compact 5S1P structure for applications that need an 18V class rechargeable power source. The datasheet specifies 3000mAh nominal capacity, 2900mAh minimum capacity, 21.0V maximum charge voltage, 12.5V discharge cut-off voltage, 0.2C standard charge/discharge, and up to 2C discharge current under supported temperature conditions. The pack uses a blue shrink-wrapped housing style with cable output and a waterproof round DC connector, with protection-board parameters covering over-charge, over-discharge, over-current, and short-circuit behavior. VTCBATT can support factory supply, sample development, OEM/ODM customization, connector matching, label requirements, and batch wholesale supply for equipment manufacturers and distributors.

01

21V Charging and 12.5V Cut-Off Control

The datasheet defines a controlled charging profile with 0.2C standard current, 21.0V constant-voltage charging, and a 30mA end condition, plus a 12.5V discharge cut-off for standard discharge testing. These pack-level limits help equipment designers match chargers, protection settings, and discharge management around documented operating values instead of relying on generic 18V assumptions.

02

Compact 5S1P 18V Pack Design

The VTC18650-5S1P pack uses a 5-series, 1-parallel 18650 structure to deliver an 18.0V nominal output with 3000mAh rated capacity in a compact pack envelope. With a listed maximum dimension of 36.0 x 57.0 x 73.0mm and a 270g weight, it is practical for equipment housings where space, cable routing, and rechargeable runtime all need to be balanced.

03

OEM Connector and Harness Customization

The product image shows a cable-output pack with a waterproof round DC connector and rubber cap, making it suitable for projects that require defined connection style and enclosure-side access. VTCBATT can support connector matching, wire length adjustment, labeling, sample validation, and batch production so buyers can adapt the same battery platform to different device layouts and installation requirements.

04

Protection Board for Safer Pack Integration

The electrical characteristic section lists protection thresholds for over-charge, over-discharge, over-current, and short-circuit release behavior, giving integrators a clearer basis for pack-level system design. For OEM products, this supports more predictable integration into enclosures, control boards, and cable assemblies while keeping the final design aligned with the pack specification and application environment.

Technical insight

Product and application details

Industrial sensor modules

The compact 36mm width fits tightly into dense sensor arrays while delivering stable 18V power for continuous low-drain operations.

Low-speed robotics accessories

Its 270g weight remains negligible for lightweight robotic joints, ensuring the 5S1P configuration provides sufficient torque without overburdening motors.

OEM electronic products

Manufacturers appreciate the standardized 57x73mm footprint, which simplifies enclosure design while offering reliable 3000mAh capacity for extended device runtime.

Outdoor control boxes

The robust cylindrical cell structure withstands vibration in outdoor enclosures, maintaining stable voltage under varying environmental conditions.

Portable lighting controllers

High capacity ensures long illumination periods for portable lights, while the 18V output efficiently drives high-power LED arrays.

Portable test instruments

Technicians benefit from the precise 18.0V nominal output, ensuring accurate readings during field diagnostics without voltage drop under load.

Security and access-control devices

Steady 18V delivery keeps access readers active during power fluctuations, preventing false locks or system resets in secure areas.

Smart logistics devices

The 3000mAh capacity supports frequent scanning cycles in logistics hubs, reducing downtime between charges for mobile inventory scanners.
