It is a lithium battery charging module.This is a solar charger for maximum power point tracking (MPPT) of single-cell lithium batteries.
It can obtain as much electricity as possible from solar panels or other photovoltaic devices and load it into rechargeable lithium batteries.
It is very easy to use,just insert the solar panel into one side of the solar charger,then insert the battery into the other side,and you can start charging.
1).Solar chargers are equipped with CN3791 power tracking battery charging circuit,and are pre-installed with four 2-pin JST/PH2.0 connection ports.
2).The input voltage is 6V,which corresponds to the working voltage of the solar panel 6V,which is very suitable for applications where the voltage difference between the input voltage and the battery voltage is large.
3).When the current output capability of the input power supply decreases,the internal circuit of CN3791 can automatically track the maximum power point of the solar panel,and the user does not need to consider the worst case,and can maximize the output power of the solar panel,which is very suitable for applications that use solar panels for power supply.
4).The constant current charging current can be set by an external resistor.
5).Trickle charge a deeply discharged battery.
6).It supports automatic recharge function,soft start function and battery terminal overvoltage protection.
7).It is equipped with charging status and charging end status indicators,and the working status can be seen at a glance.
