This protection board cannot be used for lithium iron phosphate battery, a xenon lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, children's car battery, 775 (4A) above the motor, 1W fisheye LED lamp.
The power range described applies to the following products:
Massager battery pack, LED lamp backup power supply, 12V electronics, solar street light battery pack, monitoring standby power, 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.
Description and explanation:
3 strings (series combination of 3 18650 batteries or polymer lithium batteries)
10.8V (rated voltage of polymer battery)
11.1V (rated voltage of 18650 or 3.7V lithium battery)
12.6V (voltage after fully charged lithium battery)
Discharge 10A (refers to the upper limit discharge current limit)
Note 1: Connect 0V (B-), 3.7V (B1), 7.4V (B2), and 11.1V (B+) exactly as shown. Do not intentionally short-circuit!
Note 2: After the cable is connected, it needs to be charged before output.
Note 3: When connecting 3 batteries in series, please make sure that the voltage of each battery is the same. If not, please fill each battery separately and use it 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 3 batteries should be as close as possible (2 good batteries + 1 bad battery use effect = 3 bad battery use results).
