UPS Battery Charging and Discharging Module

The UPS-12V voltage converter module is used for designing continuous and switching power supplies for routers, switches, and other network equipment or infrared alarms. when the battery is fully charged, the upper limit can produce a current of 0.1 amperes, and when the battery voltage is about to discharge, it can generate 0.8 to 0.9 watts of power. when the output is short-circuited, it automatically turns off and resumes after recharging. the ups module can be used for 12-volt devices with 0.1 amperes. note: a 3.7-volt lithium battery or polymer battery, with single or multiple cells, can be connected in parallel. 
attention: the input voltage is 5 volts.

Usage steps:

1. connect the 5-Volt input voltage to the input terminal.
2. check the output voltage with a voltmeter and ammeter.
3. connect the battery at b+ and b-.
