It features a short cable with a genuine 2-pin JST-PH connector that clicks smoothly into matching JST jacks without snagging.\n\nThe battery includes built-in protection circuitry that guards against overcharging, over-discharging (cuts off at 3.0 V), and output short circuits. Output voltage ranges from 4.2 V when fully charged to 3.7 V nominal.\n\nKey Features\n\n\n420 mAh Capacity – Approximately 1.55 Wh\n\n3.7 V Nominal – 4.2 V fully charged, 3.0 V cutoff\n\nGenuine JST-PH Connector – 2-pin with short cable for reliable connections\n\nBuilt-In Protection – Overcharge, over-discharge, and short-circuit protection\n\nThin and Lightweight – Ideal for portable and wearable projects\n\n\nSpecifications\n\n\nChemistry – Lithium-ion polymer (LiPo)\n\nNominal Voltage – 3.7 V\n\nCapacity – 420 mAh\n\nConnector – 2-pin JST-PH\n\nMax Charge Rate – 420 mA (1C)\n\n\n\nWarning: Only use a LiIon/LiPo constant-voltage/constant-current charger at 420 mA or less. Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry for damage, loose wiring, or short circuits. When using conductive thread in wearable projects, take extra care to avoid shorts which can create sparks and heat.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14423,"title":"Default Title","sku":"AF-4236","price":13.55,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
