Key Product Features

Decoded Form Factor (115570): The industry standard part number provides precise physical boundaries for device housing integration. The code indicates a nominal cell thickness of ~11mm, a width of ~55mm, and a length/height of ~70mm.
Excellent Energy Density Matrix: Offers a superior capacity-to-weight ratio compared to traditional cylindrical cells (like 18650s), allowing product designers to build flatter, sleeker, and more ergonomic enclosures.
Ready-to-Solder Terminals: Built with premium composition nickel-plated structural metal tabs extending from the top seam, allowing for direct welding or wire soldering to custom Battery Management Systems (BMS) or power boards.
Ultra-Low Self-Discharge: Formulated with high-purity chemical polymers that ensure minimal energy loss during long-term standby or storage phases, ensuring your device has power when turned on after weeks of non-use.
Flat Discharge Curve: Engineered to maintain a highly stable voltage plateau near 3.7V across the majority of its discharge cycle, ensuring consistent performance for connected microcontrollers and digital modules.

Recommended Target Applications

Consumer Electronics: Tablets, portable DVD players, oversized handheld gaming consoles, and premium e-readers.
Off-Grid Power Storage: High-capacity custom power banks, solar energy harvesting storage nodes, and backup UPS loops for small microcontrollers.
Smart IoT & Telemetry: Remote GPS trackers, long-duration environmental data loggers, and field-deployed sensor transmitters.
DIY Projects & Robotics: Autonomous rovers, remote-controlled models, or custom smart wearable hardware installations.

Critical LiPo Handling & Safety Warning

Because lithium-polymer chemistry requires strict operating boundaries, include these safety protocols on your listing to protect users and limit liability:

BMS Requirement: This is a bare pouch cell without an integrated protection circuit board (PCM/BMS). It must be wired to an appropriate external safety circuit that manages over-charging, over-discharging, and short circuits before use.
Charging Constraints: Never charge this cell with a standard unregulated power supply. Use only a dedicated CC/CV (Constant Current/Constant Voltage) lithium-polymer charger with a peak cutoff of 4.2V.
Physical Inspection: Inspect the battery enclosure before installation. Do not use, solder, or charge the cell if it exhibits any signs of denting, tearing of the outer silver laminate, leakage, or physical swelling/bloating.
