4PCS 4S 20A 14.8V Lithium for 18650 Battery BMS PCM Protection PCB Board Module 16.8V with Overcharge Over Discharge Short Circuit Protection
High-accuracy voltage detection circuit; terminal of the charger using high voltage device; low standby current consumption.
Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit); MOS transistor can control the battery charge and discharge.
Over Charge Voltage: 4.25-4.35v¡À0.05v, Over Discharge Voltage: 2.3-3.0V ¡À 0.05V.
Widespread Application: Low power inverters, massager battery packs, LED light backup power supplies, electronics, solar street light battery packs, monitoring backup power supplies, and other products.
Note: For discharge products above 3A, the discharge rate of the battery should be more than 3C. (Magnification formula: 1C rate battery, 2000 capacity equals 2AH*1=2A upper limit working current. 3C rate battery, 2000 capacity equals 2AH*3=6A upper limit working current)
