Package list::
1 x UPS Module
Note:
1. BAT connection (please connect the battery in the last step, this is very important) battery 3.7V lithium battery or Li‑pol, battery capacity: 1‑3AH ( maximum 5AH )2. At least 20AWG wire should be used for welding input and output, and the wire length should not exceed 10CM3. If the input is connected to the output, a loop will be formed, and the loop will lose 0.4‑0.6mA current4. Application Description for accessories of charging indicator: Red light‑emitting blue diodes with common anode are used. The blue light indicates whether the battery is loaded; the red light indicates whether the battery is charged, the charging red light is on, and the red light is off when it is fully charged; the red light flashing indicates that the battery is abnormal or not connected. The indicator lights need to be configured by themselves. It is recommended to select the red and blue indicator lights to be effective, and the other color two‑color indicator lights are invalid. Note: The output short circuit of the control board is invalid when charging, so please use this function with caution. When the control board is working, it will heat up, so keep a certain distance from the battery when installing!
