Note:
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.
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).
