The integrated controller accepts input voltages between 4.5 and 5.5 volts and charges a single Li-ion battery with a nominal voltage of 3.7 V to its full charging voltage of 4.2 V. The maximum charging current is 1 ampere, while the actual current is determined by the connected power supply or USB port. The module features a protection circuit that prevents overcurrents and critical voltage levels both during charging and discharging.\u003c\/p\u003e \u003cp\u003ePower is supplied via a Micro-USB connector, as commonly used on phone chargers or USB power supplies. The circuit board has solder pads for directly connecting the battery, which is particularly advantageous for compact projects. A separate charger is not required; instead, any power supply with a USB output or a computer USB port can be used.\u003c\/p\u003e \u003cp\u003eThe module can be used in portable devices such as LED lamps, small robots, or sensor networks where Li-ion batteries provide the power supply. It is also suitable for wearables or IoT prototypes that need to be charged regularly. The 1 A current is suitable for batteries with capacities of up to approximately 2000 mAh; batteries with higher capacities will take correspondingly longer to charge fully.\u003c\/p\u003e \u003cp\u003eThe battery's positive terminal must be soldered to the pad marked '+' and its negative terminal to the '-' pad. The module can be operated as long as the input voltage remains within the permissible range; voltages below or above this range may cause malfunctions or damage. Apart from a suitable USB power supply and a Li-ion battery, no additional electronics are required for operation.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eLithium-ion batteries must not be connected with reversed polarity. The module is intended exclusively for building prototypes and for testing and development purposes; it is not suitable for installation in household electrical circuits. Work on or near electrical installations must be carried out by qualified electricians; consult a qualified electrician if you have questions about safe commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x TP4056 lithium battery charger module, 1 A, Micro-USB\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66045682778461,"sku":"F23108313","price":1.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/tp4056-lithium-batterielademodul-laderegler-1a-micro-usb-funduino-3383202.png?v=1791492004","url":"https:\/\/funduino.com\/en\/products\/tp4056-lithium-battery-charging-module-charge-controller-1a-micro-usb","provider":"Funduino","version":"1.0","type":"link"}
