Product overview

VTC 18650-3S1P 10.8V 3.45Ah Li-ion Battery Pack for Smart Meter Backup, Wireless Sensor Nodes, Portable Monitoring Devices | Battery Manufacturers in China & Battery Supply Factory

The VTC 18650-3S1P is a Li-ion rechargeable battery pack from VTCBATT built for stable 3-series power delivery in compact equipment that needs dependable energy density and protected pack structure. This 10.8V nominal, 3.45Ah battery pack offers 3.35Ah minimum capacity, 12.6V limited charge voltage, 7.5V discharge cut-off voltage, standard 0.5C charging and discharging, 6A maximum discharge current, and pack dimensions of 19.5 x 37.5 x 134.0mm with a typical weight of 190g. The design includes PCM protection based on S-8254AAN protection IC and AO4407 MOSFET arrangement, with overcharge, overdischarge, overcurrent, and short-circuit protection details documented in the source file. VTCBATT supports factory supply, custom wire and connector matching, label printing, OEM/ODM pack integration, sample development, and stable batch production for customers sourcing rechargeable lithium battery packs for branded equipment and industrial projects.

01

Compact 3S1P Pack Structure

This battery pack combines three 18650 cells in a compact 3S1P structure with a maximum size of 19.5 x 37.5 x 134.0mm. The slim blue PVC-wrapped format is practical for enclosed equipment, portable housings, and products that need 10.8V output without using a bulky battery module.

02

OEM Wiring and Pack Customization

The pack format is suitable for OEM adaptation through wire length, connector matching, labeling, and pack integration changes around the documented 3S protection structure. This is useful for equipment makers that need a ready-to-install rechargeable pack for pilot runs, sample validation, or repeat factory supply.

03

Protected Output for Embedded Devices

The documented PCM design uses S-8254AAN protection control and AO4407 MOSFET switching to support overcharge, overdischarge, overcurrent, and short-circuit protection. This makes the pack better suited to embedded electronics, portable instruments, and OEM devices that need a safer rechargeable power assembly rather than loose cells.

04

Reliable Capacity in a Slim Footprint

With 3.45Ah typical capacity, 3.35Ah minimum capacity, and standard 0.5C operating conditions, the pack is positioned for low-to-medium power equipment that needs useful runtime in a narrow battery space. It supports practical energy storage for portable monitoring units, utility devices, and remote sensor equipment.
