3Pcs 4A-5A 4 String 18650 Li-ion Lithium Battery Cell Protection Module Board

Description: Model: HH-P3-10.8 Charging voltage range: 4.25-4.35v 0.05v Dimensions: 48 x 15 x 1.0mm Over-discharge voltage range: 2.3-3.0v 0.05v Maximum operating current: 4-5A Operating temperature: -40 to + 50 The maximum instantaneous current: 6-7A Storage conditions: -40 to + 80 Quiescent Current: less than 6uA Effective life: more than 50,000 hours Resistance: less than 45m Short circuit protection: Protect, need to be recharged recovery Main functions and features: Over charge protection, over-discharge protection, short circuit protection, overcurrent protection. The protective plate using Japan's Ricoh rechargeable lithium iron phosphate battery protection IC; High-accuracy voltage detection circuit; Terminal of the charger using high voltage devices; Built-in three-stage overcurrent detection circuit (overcurrent 1, overcurrent 2, load short circuit); MOS transistor can be controlled by a battery charge and discharge; Low standby current consumption. Function and Description: 1.the lithium battery with protection board according to wiring diagram, when the battery voltage is overcharge and over-discharge voltage between the voltage, and P + P- 1 second after charging, P + and P- output voltage of the battery voltage. 2.Battery charge function: between P + and P- plus charger, battery charging, the battery voltage charge to overcharge detection voltage (4.25 0.025V) the protection circuit to cut off the charging path, to achieve overcharge protection. 3.Battery over-discharge protection: in between the P + and P- connected load to the battery discharge when the battery voltage drops to over-discharge voltage (2.4 0.08V) the protection circuit, shut off the discharge path to achieve the over-discharge protection. 4.Short circuit protection: When the P + and P- short circuit protection circuit will act quickly in 5-50uS, cut off access, short-circuit protection. Overcurrent protection function: When the V- terminal voltage of (0.15 0.02V) the protection circuit will act quickly in 6.7-13.9ms, cut off access, overcurrent protection. Note: If the correct welding, testing with non-output, use other ways to activate charging about protection board. Package included: 3 x 18650 Li-ion lithium Battery Cell
