To prevent this to happen you should use your batteries with a protection board. This \u003cstrong data-mce-fragment=\"1\"\u003e3S Lithium-ion Battery Protection Board\u003c\/strong\u003e monitor protects three 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 20A like  or  based projects, 3D printers, Quadcopters, Robotics applications etc. This Board is suitable for 18650 cell having nominal voltage of 3.6V or 3.7V.\u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e \u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eShort circuit protection\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eOvercharge protection\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eOver-discharge protection\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eOvercurrent protection\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eOvercharge Voltage: 4.2V\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eMaximum Working Current: 20A\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp data-mce-fragment=\"1\"\u003e \u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eProduct Description\u003c\/strong\u003e\u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003cimg alt=\"3s 20amps\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/3s_20amps_600x600.jpg?v=1617605488\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp data-mce-fragment=\"1\"\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e1×3S Li-ion Battery Protection Board - 20A PCB BMS\u003c\/p\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46028734464171,"sku":"BCL-QC0774","price":63.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/Li-ion-Battery-Protection-Board.jpg?v=1767865826","url":"https:\/\/www.yuzxcn.com\/products\/3s-20a-li-ion-battery-18650-charger-pcb-bms-protection-board","provider":"Yuzx","version":"1.0","type":"link"}
