This results in a nominal voltage of 7.4 V when fully charged. The plastic housing protects the cells and provides stable mounting.\u003c\/p\u003e \u003cp\u003eThe two connection terminals end in solder lugs, so cables or connectors must be soldered on directly. An integrated protection circuit prevents overcharging and deep discharge of the cells, thereby significantly extending their service life. The holder is supplied without preassembled connections.\u003c\/p\u003e \u003cp\u003eApplications include portable electronic devices such as LED headlamps, cordless power tools, home servers, or mobile power systems with a nominal voltage of 7.4 V. It is equally suitable for model vehicles or radio controls in this voltage class.\u003c\/p\u003e \u003cp\u003eFour 18650 cells must be purchased separately; their condition and state of charge affect the actual output voltage. Soldering the terminals requires soldering skills; if you are unsure, consult a professional before assembly. The holder is not suitable for operation at mains voltage.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eBatteries and lithium-ion cells must not be short-circuited and must be protected against mechanical damage. This battery holder is intended exclusively for building prototypes and for testing and development purposes. Work on or near power supply systems should only be carried out if you have the necessary expertise; consult a qualified electrician if you have questions about commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1* Battery holder - 4x 18650 lithium-ion cells, without connector\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65997818233181,"sku":"F23107212","price":1.56,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/batteriefach-4x-18650-li-ionen-zellen-ohne-stecker-funduino-9587431.png?v=1791493558","url":"https:\/\/funduino.com\/en\/products\/4x-18650-lithium-ion-battery-holder-without-plug","provider":"Funduino","version":"1.0","type":"link"}
