2 szál 7,4 V-os 8,4 V-os lítium akkumulátor töltő modul USB boost töltőkártya 5V2A és 8.4V között két akkumulátor töltéséhez
2 strings of 7.4V 8.4V lithium battery charging module USB boost charging board 5V2A to 8.4V to charge two batteries
2 series lithium battery boost charging board
The 2-string lithium battery boost charging board is a dual-cell series lithium battery synchronous boost charging module with high integration and high reliability. The input voltage is 5V, the BAT voltage is 8.4V, and the charging efficiency is 94% when the charging current is 1.2A. . Charging integrates various protection functions: input over-voltage, input under-voltage, output over-voltage, output short-circuit, chip over-temperature, and a maximum charging time of 24 hours.
