The WLY103443 3.7V 1500mAh 1S LiPo battery pack is a single-cell lithium polymer pouch battery engineered for lightweight and space-efficient electronic designs. With a 7.4Wh energy rating, 1C max charge/discharge rate, and stable 3.7V nominal output, it ensures consistent performance for micro power-critical applications. This battery comes with bare open wires (Red = V , Black = GND) for direct integration with 3.7V CC/CV lithium chargers (TP4056, 1S LiPo BMS, boost converters, and embedded IoT PCBs). Its polymer pouch form factor (10×34×43mm) makes it highly suitable for compact enclosures where cylindrical cells cannot fit. Designed for: Wearable electronics Micro drones (1S flight packs) IoT devices (ESP32/ESP8266 sensor nodes) Portable LED lights & embedded systems RC micro builds & DIY electronics Features High-Capacity Power: 1500mAh for long backup Stable Output: 3.7V nominal voltage Lightweight & Portable: ≈30g micro pouch cell 1S Configuration: Single cell LiPo pack (1S) Direct Integration: Open wire output Reliable Cycle Life: ≥300 charge cycles at 0.5C (20±5°C) Package Includes 1 × WLY103443 3.7V 1500mAh 1S LiPo Battery Pack (Open Wire Output) Battery Specifications Model No.: WLY103443 Chemistry: Lithium Polymer (LiPo), 1S Single Cell Nominal Voltage: 3.7V Capacity: 1500mAh Energy Rating: 7.4Wh Max Charge/Discharge Rate: 1C Continuous Charge/Discharge Current: 0.5C Connector Type: Open wire output (Red = 3.7V , Black = GND) Life Cycles: ≥300 cycles (0.5C to 2.75V, <80% after 300 cycles, 20±5°C) Cell Dimensions: 10mm × 34mm × 43mm Max Cell Size incl.
