Features:
The 2 series lithium battery boost charging board is double link series lithium battery synchronous boost charging module
High quality material with high integration and high reliability.
The charging efficiency is 94% at the input voltage of 5V, bat voltage 8.4v and charging current of 1.2A.
Charging integrates various protection functions: input overvoltage, input undervoltage, output overvoltage, output short circuit, chip over temperature, and maximum charging time of 24 hours.
The no-load voltage of the module is 4.3V, which can only be increased to 8.4V after two lithium batteries are connected
