The slim, lightweight form factor makes it ideal for wearables, IoT devices, and portable electronics projects.\n\nThe 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.\n\nKey Features\n\n\n350 mAh Capacity – Approximately 1.3 Wh of energy\n\n3.7 V Nominal – Output ranges from 4.2 V (fully charged) to 3.0 V (cutoff)\n\nBuilt-in Protection – Overcharge, over-discharge, and short circuit protection\n\nGenuine JST-PH Connector – 2-pin connector with short cable\n\nLightweight – Thin LiPo form factor\n\n\nSpecifications\n\n\nChemistry – Lithium-ion polymer (LiPo)\n\nNominal Voltage – 3.7 V\n\nCapacity – 350 mAh\n\nConnector – 2-pin JST-PH\n\nProtection – Overcharge, over-discharge, short circuit\n\n\nIdeal For\n\nWearable electronics and small IoT devices\nArduino, Feather, and microcontroller projects\nPortable gadgets and prototypes\n\n\n\nSafety 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.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5195,"title":"Default Title","sku":"AF-4237","price":11.6,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":99,"option1":"Default Title"}]}
