Weighing in at approximately 5 grams and featuring a footprint smaller than a postage stamp, this ultra-micro cell is engineered for nano-scale engineering. Despite its diminutive size, it harnesses advanced lithium-ion chemistry packed within a flexible foil pouch to deliver a steady 3.7V output, keeping your miniaturized circuits running reliably.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eBecause this battery is designed for extremely small applications, it typically comes pre-terminated with a micro-pitch connector—most commonly a JST-GH or Molex PicoBlade (1.25mm or 1.0mm pitch)—rather than the bulkier 2.0mm JST-PH found on larger cells. Even with its tiny form factor, high-quality models still conceal a miniaturized Protection Circuit Module (PCM) beneath the top layer of Kapton tape, ensuring the battery remains safe from volatile over-charge and over-discharge scenarios.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eKey Features \u0026amp;
