10pcs 2S 7.4V Lithium Battery Protection Board Module 8.4V 8A BMS PCM Charging Discharge for Li-ion 18650

Package Content:10pcs 7.4V 8.4V 2S Lithium Battery Protection Board Size: 41 x 16 x 3.5mm 2S 7.4V Li-ion battery protection board, built-in three-stage over-current detection circuit (over current 1, over current 2, or load short circuit). Design compact: high-accuracy voltage detection circuit; terminal of the charger using high voltage device; MOS transistor can control the battery charge and discharge; low standby current consumption. High performance: Life cycle :more than 50000hours; Resistance:Less than 300mΩ; Short cut protection :Protectable,charge can repair; Size: 40*15*3.5mm.Resolutions: Over charge voltage:4.25-4.35v±0.05v;Over dishcarge voltage: 2.5-3.0v±0.05v;Over dishcarge voltage: 2.5-3.0v±0.05v; Max continuous continuous current:8A ;Max peak current:15A. Troubleshooting: when the output (P+ P-) is 0. Sometimes it is necessary to reset the board. It requires an 8V-12V (i.e. 9V) battery, which is connected to the terminals P+ and P for a few seconds, then the board is reset and the output is correct.
