The attributes of the lithium battery protection board:
Model: HX-3S-F100A Overcharge voltage range: 4.28v±0.05v
Size: 70*60*8.5mm Over-discharge voltage range: 2.5±0.05v
Maximum operating current: 100A ( pay attention to heat dissipation ) Operating temperature: -40—+50°C
Upper limit instantaneous current: 100-120A Storage conditions: -40– +80℃
Quiescent current: less than 30uA Effective life: more than 30,000 hours
Internal resistance: less than 300mΩ. Short circuit protection: can be protected, delayed self-recovery.
Balance current: 65 mA
Charging voltage: 12.6V-13V Upper limit of charging current: 10A
Point T description: Adding a normally closed temperature sensor switch can expand the temperature protection function, and the 0R resistance beside the solder joint should be removed.
Note: For products with a current above 3A, the battery discharge rate must be above 3C.
The magnification calculation formula: For a battery with a 1C magnification, the capacity of 2000 is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
The battery will heat up during use, which means that the battery rate is not applicable. In this case, the battery cannot be used for a long time and the battery will be damaged quickly.
Note 1: Wiring 0V(B-), 3.7V(B1), 7.4V(B2), 11.1V(B+), C- charge negative, C+ charge positive, P- output negative, P+ output positive, don’t Intentionally short circuited!
Note 2: After the line is connected, it needs to be charged before output.
Note 3: When connecting 3 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are not the same, please charge each set of batteries separately and then use them in series. During the discharge test, the battery with the fast voltage drop is a bad battery.
Explain: Don’t mix good batteries and bad batteries together! The closer the capacity/internal resistance of the 3 sets of batteries, the better! (2 good batteries + 1 bad battery use effect = 3 poor batteries use effect).
