It includes an integrated protection board, insulated rubber tape, and a JST 1.25 plug. With a capacity of 3000mAh, it provides extended run time for projects like the ESP32 LoRa V3\/V4, Wireless Tracker, Mesh Node T114, and Mesh Node T096. The protection board guards against overcharge, over-discharge, and short circuits, but note that it can be damaged by sustained high currents beyond its rated limits.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is the recommended charging current for this battery?\u003c\/h2\u003e\n\u003cp\u003eFor best safety and longevity, charge at 0.6A (600mA). The maximum safe charging current is 1.5A. Similarly, the recommended discharge current is 0.6A, with a ceiling of 1.5A. Exceeding these values may permanently damage the protection board.\u003c\/p\u003e\n\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChemistry\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLithium Polymer (LiPo)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.7V nominal (4.2V full charge)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCapacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3000mAh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eJST 1.25 (compatible with SH1.25-2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProtection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOvercharge, over-discharge, short circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~48g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eProtection Board Details\u003c\/h2\u003e\n\u003cp\u003eThe built-in PCB stops charging when the cell reaches 4.2V, preventing overcharge. When voltage drops to 3.0V, the board disconnects to avoid over-discharge. In case of a short circuit, it shuts off in milliseconds. However, these protections are not a guarantee—if the battery is shorted directly (bypassing the board), high current can still damage components. Always stay within the recommended current limits.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Devices\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eESP32 LoRa V3 \/ V4\u003c\/li\u003e\n\u003cli\u003eWireless Tracker\u003c\/li\u003e\n\u003cli\u003eMesh Node T114 \/ T096\u003c\/li\u003e\n\u003cli\u003eAny development board with a SH1.25-2 plug\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant Usage Notes\u003c\/h2\u003e\n\u003cp\u003eDo not exceed 1.5A charge or discharge current. The protection board can fail if subjected to continuous high current above its rating. Always charge in a safe area and avoid physical damage to the cell. The insulated rubber tape helps secure the connector but does not replace proper handling.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eCan I use this battery directly with an ESP32 without a separate voltage regulator?\u003c\/h3\u003e\n\u003cp\u003eMost ESP32 boards can run directly on 3.7V LiPo voltage (range ~3.0V-4.2V), but check your board's input tolerance. Many include an onboard regulator.\u003c\/p\u003e\n\u003ch3\u003eDoes the protection board support balancing?\u003c\/h3\u003e\n\u003cp\u003eNo, this is a single-cell (1S) battery, so balancing is not needed.\u003c\/p\u003e\n\u003ch3\u003eWhat is the physical size of the battery?\u003c\/h3\u003e\n\u003cp\u003eExact dimensions are not specified, but typical 3000mAh LiPo pouches are roughly 65x35x8mm.
