5V 1A UPS Uninterrupted Power Supply Module 3.7V Polymer 18650 Lithium Battery Step Up Reverse Overvoltage Protection Board

Parameter:
Input: 5V1A or more
Output: 5V1A (max)
Battery: polymer lithium battery, 18650 lithium battery. (recommended capacity below 10000ma)
Input: Reverse connection protection, input overvoltage protection, automatically cut off the input power to battery power mode when the input exceeds 6V.
Battery terminal: Reverse connection protection Short circuit protection Reverse connection will not be damaged during charging. When the external power input exceeds 20v, it will break through the protection unit.
Output: Only normal load can be supplied, other power adapters cannot be connected, and the inverter must be burned, the output short circuit is fine, and the load does not sleep when the load is small.
Volume: 33*15* 4.5 mm
Wiring port:
Input mode: IN+ input positive, IN- input negative,
Output mode: OUT+ output positive, OUT-output negative,
Battery: B+ is connected to the battery positive pole, B- is connected to the battery negative pole,
Indicator light (need to be added): R+ is the external power supply working status, G+ is the battery capacity indication. The battery capacity is indicated by the flashing frequency. The faster the flashing, the larger the battery capacity, and the automatic shutdown when no load or when not charging.
Jumper (J1) Description: Used to set the power of the external power supply. The default is 1A or less. When the short-circuit jumper requires external power output power of 5v 2A, the jumper is to switch 0.5A /1A current, and the priority supply load. The remaining current is transferred to the battery for charging
Note: The board will heat when charging, so the board needs to keep a distance from the battery during assembly. Secondly, the battery is optimistic about polarity, please do not reverse it, so as not to damage the management chip. When the circuit works in the state of filling and edge, no Short circuit protection to avoid damage to the device
