To prevent this to happen, you should use your batteries with a protection board. This \u003cstrong\u003e2S Lithium-ion Battery Protection Board\u003c\/strong\u003e monitor protects two cells connected in series by monitoring the voltage and current in and out of the battery pack and if any unsafe condition happens then it will cut off the battery from the load or the charger. This can be used in any DIY project where the current does not exceed 3A like  or  based projects, 3D printers, Robotics, etc.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e Note: Product may be differ from the picture shown here.\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eShort circuit protection\u003c\/li\u003e\n\u003cli\u003eOvercharge protection\u003c\/li\u003e\n\u003cli\u003eOver-discharge protection\u003c\/li\u003e\n\u003cli\u003eOvercurrent protection\u003c\/li\u003e\n\u003cli\u003eOver-Discharge Detection Voltage: 3.0V\u003c\/li\u003e\n\u003cli\u003eMaximum Working Current: 3A\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40 to 50°C\u003c\/li\u003e\n\u003cli\u003eInternal Resistance: Less than 45mΩ\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct Description\u003c\/strong\u003e\u003c\/h3\u003e\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"2S Lithium-ion Battery Protection BMS Board Pinout\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/Battery-Protection-Board_480x480.jpg?v=1589008645\"\u003e\u003c\/div\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cspan\u003eTo connect your two cells of nominal voltage 3.7 V to the protection board, you need to first connect them in series and then connect the positive terminal to the \u003cem\u003eB+\u003c\/em\u003e and negative terminal to \u003cem\u003eB-\u003c\/em\u003e and common terminal between the two cells to \u003cem\u003eBn.\u003c\/em\u003e To connect the load or charger to this board, connect positive terminal to \u003cem\u003eP+\u003c\/em\u003e and negative terminal to \u003cem\u003eP-. \u003c\/em\u003emake sure the two positive and negative wires do not get shorted.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e1×7.4V, 3A 2S Lithium-Ion Battery Protection Board\u003c\/p\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46028700450987,"sku":"BCL-QC0153","price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/2S-Li-ion-BMS.jpg?v=1767864917","url":"https:\/\/www.yuzxcn.com\/products\/2s-li-ion-battery-protection-board","provider":"Yuzx","version":"1.0","type":"link"}
