ICR18650-1S3P 3.7V 7800mAh Li-ion rechargeable battery for IoT sensor modules, portable instruments, backup power systems
The VTCBATT ICR18650-1S3P 3.7V 7800mAh Li-ion rechargeable battery pack is built from a cylindrical lithium-ion cell configuration for equipment that needs higher capacity in a compact single-series pack. The datasheet specifies 7800mAh nominal capacity, 7650mAh minimum capacity, 3.7V nominal voltage, 4.2V maximum charge voltage, 2.75V discharge cut-off voltage, 0.2C standard charge and discharge current, 0.5C rapid charge current, and 0.5C maximum discharge current. The finished pack dimensions are 20.0mm max thickness, 57.0mm max width, and 68.0mm max length, with approximately 140g weight, blue PVC wrapping, 60+/-5mm wire length, UL1007 24AWG leads, and a JST/SMP-02V-BC connector. The PCM design uses a DW01+ protection IC with two dp8205 MOSFETs, supporting over-charge, over-discharge, over-current, and short-circuit protection functions defined in the product specification. VTCBATT can support factory-direct supply, OEM/ODM battery pack development, connector matching, labeling, sample confirmation, and stable batch production for customers that need a custom lithium battery pack for commercial electronic devices.

Application for 3.7V 7800mAh Li-ion battery pack
This 3.7V 7800mAh Li-ion battery pack is suitable for rechargeable IoT sensor modules, portable test instruments, compact backup power systems, wireless alarm panels, access control accessories, telemetry terminals, GPS tracker modules, low-voltage LED lighting packs, and other embedded electronic products that can operate within the datasheet charge and discharge limits. The 1S3P structure gives the pack a higher capacity than a single 18650 cell while keeping a flat, compact pack format that fits many plastic enclosures and equipment compartments. The 60+/-5mm lead wire and JST/SMP-02V-BC connector make it easier for OEM engineers to integrate the pack into a PCB, charger board, or device housing without redesigning the power interface from the beginning. For different application projects, VTCBATT can provide connector matching, wire length adjustment, PCM design support, label customization, sample testing, and factory-direct wholesale supply for distributors, equipment manufacturers, and brand owners that need repeatable lithium battery pack production.
