DC 5V 1A UPS Uninterrupted Power Supply Module Step Up Booster Voltage Converter for 18650 Lithium Battery Charge Protection
Describe:
Input: above 5V1A
Output: 5V1A (max)
Battery: polymer lithium battery, 18650 lithium battery. (recommended capacity below 10000ma)
Input: The external power supply voltage should be less than 6V.
Battery side: reverse connection protection, short circuit protection, reverse connection will not be damaged during charging.
Output terminal: Only supply common load, can not connect other power adapters, and the reverse connection will burn, the output is short-circuited, and it will not sleep when the load is small.
Volume: 33*15*4.5mm
Wiring port:
Input method: IN+ input positive level, IN- input negative electrode, output method: OUT+ output positive level, OUT- output negative electrode,
Battery: B+ is connected to the positive pole of the battery, B- is connected to the negative pole of the battery,
Indicator light (you need to add it yourself): R+ is the working state of the external power supply, G+ is the battery capacity indicator, and the battery capacity is displayed by the frequency of flashing. The faster the flashing, the more the battery capacity is, and it will automatically turn off when it is not loaded or not charged.
Jumper (J1) Description:
It is used to set the power of the external power supply. The default is to short the jumper. The external power supply current needs to be greater than 1A;
When the external power supply current is less than 1A, it is necessary to disconnect the jumper and switch the 0.5A current for power supply, the load is given priority, and the remaining current is transferred to the battery for charging.
Precautions:
The circuit board will heat up when charging, so the circuit board needs to keep a distance from the battery when assembling. Secondly, the battery is optimistic about the polarity, please do not connect it in reverse, so as not to damage the management chip. so as not to damage the device
