Charging indicator description.
Module can roughly judge the working status by two LEDs and states, CHRG is red light, STDBY is blue light.
Battery charging state red light is high, blue light is not bright, flush full bright blue light, red light is slightly bright.
If there is a boost output, will be different according to the output power, there may be charging will always be high red light, not connected without a load, blue light on, red light slightly bright.
Instructions for use.
The module supports type-c interface input and behind the labeled input solder joint input, choose one of them can, the recommended voltage of about 5V. Module marked with two outputs these two outputs are the same, the line is connected in parallel, you can choose one of them - group can.
How to connect the battery.
If your battery comes with a protection board, optional products without discharge protection, the battery connected to the B + and B-, must be shorted to the T point, in order to charge and discharge.
If your battery does not come with a protection plate, choose a product with discharge protection, this is very important, because the battery is likely to be over-discharged to cause battery scrap, most competitive products of the same kind are not discharge protection, the battery is connected to B + and B-, you can not short the T point, otherwise the discharge protection will fail.
After connecting the line you can use a screwdriver to adjust the output voltage you want.
Battery selection 3.7V lithium battery, full voltage of 4.2V, battery type can be 18650, polymer and batteries.
