Notice:The protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, children’s car battery, 775 (4A) motor, 1W fish eye LED light, please pay please pay attention to the combination of the purchase of customers! theNote 1: Strictly according to the card wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B3), 14.8V (B +), do not deliberately short circuit !Note 2: after the need to line the first, will have exit.Note 3: 4 groups of batteries in series, please make sure that the voltage of each group of batteries, if not the same, please fill each battery separately and then used in series. Discharge test, the voltage drop is fast, that group of batteries is bad battery.(2 good battery + 2 bad battery use effect = 4 bad battery use effect). 4 battery capacity / resistance closer to the better! (2 good battery + 2 bad battery use effect = 4 bad battery use effect).
