Product overview

VTC18650-1S4P 3.6V 13.6Ah Li-ion Battery Pack for Industrial control devices, Wireless data terminals, Portable service analyzers | Battery Manufacturers in China & Battery Supply Factory

The VTC18650-1S4P 3.6V 13.6Ah Li-ion battery pack from VTCBATT is a cylindrical lithium ion rechargeable battery assembly built in a 1S4P structure with a nominal capacity of 13.6Ah, minimum capacity of 12.8Ah, 4.2V limited charge voltage, 2.5V discharge cut-off voltage, and a compact 37.0 x 37.0 x 67.0 mm pack size at approximately 220 g. The datasheet also shows PCM protection, a three-wire output with 80±5 mm lead length, JST/PHR-3P connector arrangement, and defined operating temperature windows for charging and discharging. VTCBATT supports factory supply, sample development, custom cable and connector matching, OEM/ODM battery pack production, and stable batch delivery for customers that need dependable lithium battery pack sourcing.

01

Compact Mechanical Integration

With maximum pack dimensions of 37.0 x 37.0 x 67.0 mm and weight around 220 g, this battery pack is suited to projects that need meaningful capacity in a constrained footprint. The blue PVC-wrapped pack structure, 80±5 mm lead wire, and JST/PHR-3P connector arrangement help reduce extra mechanical adaptation work during product development and small-batch manufacturing.

02

High Capacity 1S4P Runtime

The VTC18650-1S4P battery pack uses a 1S4P cylindrical Li-ion structure to deliver 13.6Ah nominal capacity in a compact body, giving OEM devices longer operating time without moving to a much larger enclosure. This makes it practical for portable monitoring equipment, communication modules, and reserve-power electronics that need stable low-voltage energy storage with moderate current output.

03

OEM Wiring and Connector Flexibility

VTCBATT can support application-oriented battery pack customization based on the source design, including connector matching, lead-wire adjustment, label updates, and project-specific pack configuration for OEM/ODM supply. This is useful for industrial device brands, system integrators, and distributors that need a factory-direct lithium battery pack with room for assembly-level adaptation.

04

PCM Protected Pack Output

The datasheet includes PCM protection characteristics covering over-charge, over-discharge, short-circuit, and over-current control, helping equipment builders integrate a more controlled battery pack into low-voltage systems. The pack also uses a three-wire output layout with red, black, and white leads for power and temperature-related integration, which supports cleaner assembly into finished devices.
