The protection board cannot be used for lithium iron phosphate battery, a xenon lamp, hand drill battery pack, can not be used for an electric fish battery pack, electric bicycle battery pack, children's car battery, 775 (4A) above the motor, 1W fisheye LED lamp.
The power range described applies to the following products:
Massager battery pack, LED lamp backup power supply, 12V electronics, solar street light battery pack, monitoring standby power, and other products.
Note: For products discharged above 3A, the battery discharge rate should be 3C or more.
Magnification formula: 1C rate battery, 2000 capacity equal to 2AH*1=2A operating current.
3C rate battery, 2000 capacity equal to 2AH*3=6A operating current.
In use, the battery will heat up and the battery power is not applicable. This condition cannot be used for a long time and the battery will be damaged quickly.
The lithium battery protection board properties:
Model: HX-3S-FL25A-A Over charging voltage range: 4.25-4.35v±0.05v
Size: 56*45*4.0mm Over discharge voltage range: 2.3-3.0v±0.05v
Maximum operating current: 0-15A (note heat dissipation) Operating temperature: -40---+50°C
Upper limit instantaneous current: 20-25A Storage condition: -40-- +80°C
Static current: less than 30uA effective life: more than 30000 hours
Internal resistance: less than 100mΩ Short-circuit protection: protection, delay self-recovery.
Balance current: 45 mA
Charging voltage: 12.6V-13V
Test Point Description: S1 S2 short circuit P + P- will output voltage, indicating that all MOS protection is normal, plus a normally open temperature detection can expand the temperature protection.
