LCUS-1 type USB Relay Module Electronic Converter PCB USB Intelligent Control Switch

 This protection board can not be used for lithium iron phosphate battery, xenon lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, children"s car battery, 775 (4A) above motor, 1W fisheye LED lamp, used in the above Please pay attention to the customers who purchased the combination! .


The power range described applies to the following products:

Low-power inverters, massager battery packs, LED lamp backup power supplies, electronic products, solar street light battery packs, monitoring standby power supplies, and other products.

Note: For products discharged above 3A, the battery discharge rate should be 3C or more.

Magnification formula: 1C rate battery, 2000 capacity equal to 2AH*1=2A upper limit operating current.

3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit operating current.

In use, the battery will heat up and the battery power is not applicable. This condition cannot be used for a long time and the battery will be damaged quickly.



Note 1: Connect 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B3), and 14.8V (B+) in strict accordance with the diagram. Do not intentionally short circuit!

Note 2: After the cable is connected, it needs to be charged before output.



Note 3: When connecting 4 sets of batteries in series, please make sure that the voltage of each set of batteries is the same. If not, please fill each set of batteries separately and use them in series. In the discharge test, the battery with a faster voltage drop is a poor battery.



Explain: Don"t mix good batteries and bad batteries together! The capacity/internal resistance of the 4 batteries should be as close as possible (2 good batteries + 2 poor battery use effects = 4 poor battery use results).
