2PCS DC 5V 1A UPS Uninterrupted Power Supply Module 18650 Lithium Battery Protection

【5VUPSBOARD】 Uninterrupted power supply module DC 5V 1A UPS 18650 lithium battery protection board 【Specifications】 ✔Input: above 5V1A✔Output: 5V1A (max) ✔Battery: Li-polymer battery, 18650 lithium battery. (Recommended capacity is less than 10000mA) ✔ Input terminal: reverse connection protection, protection from input overvoltage, automatic cut-off of input power when the input exceeds 6V and switch to battery power mode. 【Terminal】 Battery terminal: reverse connection protection Short circuit protection Reverse connection will not be damaged when charging. When the external power input exceeds 20V, the protection unit will be faulty. Output terminal: can only supply ordinary loads and cannot be connected to other power adapters and will burn if connected backwards. 【Note】 The battery capacity is displayed by the flashing frequency. The faster it blinks, the greater the battery capacity, and it will automatically shut down when it is low or not charged. The card heats up during charging, so the card must be kept away from the battery when mounting. Second, the battery is optimistic about polarity. 【Wiring port】 ✔ Input mode: IN + input +, IN-input-✔ Output mode: OUT + output +, OUT-output-✔ Battery: B + connects to battery +, B- connects to battery - ✔ Indicator light (to add alone): R + is the working status of the external power supply, G + is the battery capacity indicator.
