Featuring a protective cover and an integrated ON\/OFF slide switch, this battery holder offers safe battery storage, convenient power control, and easy battery replacement. It is widely used in robotics, Arduino projects, ESP32 development, IoT devices, LED lighting, portable instruments, DIY electronics, battery-powered prototypes, and embedded systems.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eConstructed from high-quality ABS plastic, the holder incorporates nickel-plated steel spring contacts and flat terminals to ensure excellent electrical conductivity and secure battery retention. The spring-loaded contacts allow batteries to be installed and removed without soldering directly to the cells, helping prevent heat damage while simplifying maintenance. The protective cover keeps the batteries firmly in place and protects them from dust, accidental contact, and mechanical movement during operation.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eThe holder is commonly available in a 2-cell series (2S) configuration, providing a nominal output voltage of approximately 7.4V when powered by two 3.7V lithium-ion batteries and up to 8.4V when the batteries are fully charged. The integrated ON\/OFF slide switch enables users to conveniently disconnect power without removing the batteries, helping conserve battery life during storage and improving overall safety. Its pre-attached wire leads allow for quick and easy integration into electronic circuits.\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003eDesigned for durability and long-term use, the battery holder supports both protected and most standard unprotected 18650 lithium-ion cells. Its lightweight construction, reusable design, and dependable performance make it an excellent choice for students, hobbyists, engineers, educators, and makers developing rechargeable battery-powered electronic projects.\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eKey Features\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\u003cspan\u003eDesigned to hold two standard 18650 lithium-ion batteries\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIntegrated ON\/OFF slide switch\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProtective battery cover included\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDurable high-quality ABS plastic construction\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNickel-plated steel spring contacts\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSecure battery retention\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReliable electrical conductivity\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEasy battery installation and replacement\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNo soldering required directly on batteries\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePre-attached wire leads for quick circuit connection\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCommonly wired in a 2-cell series configuration\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProvides approximately 7.4V nominal output\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompatible with protected and standard 18650 lithium-ion cells\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLightweight and compact design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHelps conserve battery life using integrated power switch\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProtects batteries from dust and accidental contact\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for Arduino, ESP32, Raspberry Pi, STM32, and other embedded platforms\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIdeal for robotics and automation projects\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSuitable for portable electronic devices\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReusable and easy to maintain\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLong service life\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePerfect for DIY electronics and prototype development\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roboracter","offers":[{"title":"Default Title","offer_id":46862638874678,"sku":"YNDH1F2EYJ","price":54.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/0731\/2694\/files\/18650_Dual_Battery_Holder_with_Cover_and_On_Off_Switch-1.png?v=1783947555","url":"https:\/\/roboracter.in\/products\/18650-dual-battery-holder-with-cover-and-on-off-switch","provider":"Roboracter","version":"1.0","type":"link"}
