The product is made of high-quality materials with guaranteed quality. The module has the function of bidirectional voltage rise and fall, and can output fixed 5V or 20V regardless of changes in battery voltage. The product design is and adopts TYPE-C USB interface, making it convenient to use. Almost all fast charging protocols on the market are supported. IP2368 full protocol 100W fast charging output, supporting not only laptops but also almost all mobile phone fast charging protocols. Product precautions: The bidirectional C port of the product can only be connected to unidirectional electrical appliances or chargers, such as charging heads, mobile phones, and other electrical appliances. Prohibiting bidirectional C-port links to modules with bidirectional C-ports may result in frequent switching between modules that cannot be recognized, and in severe cases, may be damaged. The module has the function of bidirectional voltage rise and fall, and can output fixed 5V or 20V regardless of battery voltage changes. It should be noted that a charging and discharging voltage of 20V is required for 100W, and if the output voltage is 12V, the maximum current can only reach 3a, which is 36W. Power supply voltage: 4 series of lithium batteries (resistance can be modified to support 2-6 series of lithium batteries or iron phosphate front batteries), the discharge capacity of the battery pack must be 5a, and the battery pack must be equipped with a protective plate for use. Continuous working current: 18A Overcharge voltage: 4.235V 0.025V Instantaneous current: 30A Overcharge release voltage: 4.190.05V Charging voltage: 16.8-17V Overdischarge voltage: 2.8+0.08V Charging current: 1-10A Overdischarge release voltage: 3.0+0.1V Balanced starting voltage: 4.190.05V Product name: IP2368 bidirectional 100w fast charging module Product Master IC: IP2368 Hole center distance: 43.5x28.5mm (4 holes for M2 screws) Instructions for modifying battery parameters: IP2368 supports 2/3/4/5/6 series cells, and the number of battery series cells can be through external resistors. IP2368 supports external resistors to choose between regular lithium batteries or lithium iron phosphate batteries. The external resistor can be set to a full charge voltage of 4.15V/4.2V/4.3V/4.35V/4.4V, and the full charge voltage of lithium iron phosphate batteries can be set to 3.5V/3.55V/3.6v/3.65V/3.65V/3.7V. Specific modification method: R2 suspended=ordinary lithium battery R2 short circuited=lithium iron phosphate battery R7 sets the number of battery strings: 6.2k=2 strings 91k=3 strings 13k=4 strings 18k=5 strings 27k=6 strings Color:As Shown Material:PC Package Contents: 1 * IP2368 Bidirectional 100W Fast Charging Module Only the above package content, other products are not included.
