## Description

A compact 3.7 V 350 mAh lithium-ion polymer (LiPo) battery with a short cable and genuine 2-pin JST-PH connector. The slim, lightweight form factor makes it ideal for wearables, IoT devices, and portable electronics projects. The battery includes built-in protection circuitry that guards against overcharging (above 4.2 V), over-discharge (below 3.0 V), and output short circuits. The genuine JST connector clicks smoothly in and out of matching jacks without snagging. Key Features 350 mAh Capacity – Approximately 1.3 Wh of energy 3.7 V Nominal – Output ranges from 4.2 V (fully charged) to 3.0 V (cutoff) Built-in Protection – Overcharge, over-discharge, and short circuit protection Genuine JST-PH Connector – 2-pin connector with short cable Lightweight – Thin LiPo form factor Specifications Chemistry – Lithium-ion polymer (LiPo) Nominal Voltage – 3.7 V Capacity – 350 mAh Connector – 2-pin JST-PH Protection – Overcharge, over-discharge, short circuit Ideal For Wearable electronics and small IoT devices Arduino, Feather, and microcontroller projects Portable gadgets and prototypes Safety Warning: Only use a LiIon/LiPo constant-voltage/constant-current charger at 350 mA or less (100–350 mA recommended). Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture the battery. Never charge or use unattended. Always check that your charger's JST polarity matches before connecting — reversed polarity can destroy the battery.
