2S Li-ion 18650 Lithium akkumulátortöltő védőkártya 7,4 V túláram túltöltés túlkisülés védelem 4A 2 sorozatú BMS
2S Li-ion 18650 Lithium Battery Charger Protection Board 7.4V Overcurrent Overcharge Overdischarge Protection 4A 2 Series BMS
Features:
1.Internally Install High Precision Volage Detection Circuit
2.Terminal Connecting With Charger Adopt High Withstand Voltage Compoents
3.Internally Install 3-Phase Overcurrent Detection Circuit (overcurrent 1,overcurrent 2,load short circuit)
4.Using MOS Tube Can Control Battery Charging/Discharging
5.Wide Operating Temperature Range:-40 Celsius ~85Celsius
6.Low Consumption Current
Connection Introduction:
1.B :connect with battery positive
2.MB:connect with battery 1 and battery 2 joint
3.B-:connect with battery negative
4.P :connect with charging/discharging port positive (charging port/discharging port are commonly used)
5.P-:connect with charging/discharging port negative (charging port/discharging port are commonly used)
Notice:
1.During connection,pay attention to input/output voltage,load current using condition,and make sure that board power consumption will not surpass tolerance consumption
2.When connect with battery,it may not discharge;in this condition,continuous charging can let it restore to normal operating state
3.When overcharging battery and overdischarging battery are mixed up,it will become charging and overdischarging state,both of them cannot perform charging and discharging
4.Although this protection board internallt installs anti-static protection circuit,please don't force too high static electricty on protection board
