Feature:
1. Auto Charging: Charge the battery when there is power, and automatically use the battery to supply power when the power is off. The battery automatically charges and discharges.
2. Good Protection: With input reverse connection protection, overheating protection, over discharge protection and short circuit protection.
3. Wide in Utility: Can work as power supply, battery charger, mobile power supply, power conversion, infrared alarm, switch and other network equipment, router, battery car modification, etc.
4. Stable Working: Able to step up the input voltage to charge the battery, the battery charger module can provide you with uninterruptible power supply.
5. Easy to Install: Designed to have a light weight and a compact size as well, the installation of this boost charger board is very convenient.
Specification:

Application: For power supply, battery charger, mobile power supply, power conversion, infrared alarm, switch and other network equipment, router, battery car modification, etc.
How to Use:
1. Connect the correct input voltage to the input terminal.
2. Check the output voltage with voltmeter and ammeter.
3. Connect the battery at B+ and B-.
4. The DC UPS 12V 12W continuous power supply control board is used to design continuous power supply for network equipment such as routers, switches or infrared alarms. When the battery is fully charged, the upper limit can output 1A current. When the battery voltage is about to be emptied, 8-9W power can be output. When the output is short circuited, it will automatically shut down. After recharging, it will recover. Before the battery is emptied and shut down, a flashing prompt will appear. After flashing several times, it will enter the low power protection and shut down the output! Note that The input or output interface can share the negative pole, but the positive pole cannot be shared, and the battery terminal cannot share the negative pole! Note that the current motherboard has a charging time detection function. The default slow charging is suitable for batteries within 8Ah. The jumper cable is changed to fast charging for batteries within 8-15Ah. The high power UPS continuous power supply motherboard developed for 12V 1.5A routers can also be used for 12V 1A devices. During charging, the minimum input voltage is 5V, and the default charging current is 0.5-0.6A. It is unnecessary to replace the charger. In addition, jumper cable can improve the charging speed. If the charging is accelerated, the power supply must be replaced to prevent potential safety hazards, and the power must be doubled at least. For example, the customer uses a 12V 1.5A power supply. If the charging is fast, the power supply needs to be replaced with a 12V 2.5A-3A power supply, and more margin needs to be reserved.

Battery Charger Module
Note:
1. The maximum output current is 1A, and the output 1A cannot be maintained.
2. The positive and negative poles of the input power supply shall not be reversed, otherwise the module will be damaged.
3. Users can install a common anode red blue LED as the charging indicator. The blue light indicates whether the output terminal has load, and the red light indicates charging. A flashing red light indicates that there is no battery. The red light goes out after charging.
4. Due to the large current, it is recommended to use thicker wire with a section greater than 1.5mm².
