3 sorozat 12V18650 lítium akkumulátor védőkártya 11,1V 12,6V túltöltés és túlkisülés védelem üzemi áram 8A
3 series 12V18650 lithium battery protection board 11.1V 12.6V overcharge and overdischarge protection working current 8A
Product parameter
Name:1.1V Li-ion BMS 8A
Product size: 30*30*3mm
Upper limit operating current: 8A Upper limit instantaneous current: 12A
Overcharge voltage range: 4.25±0.05v Overdischarge voltage range 2. 5v ±0. 05v
Charging voltage: 12. 6V-13V Quiescent current: small \T30uA
Short circuit protection: can protect, delay self-recovery
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 OV (B-), 3.7V (Bl), 7.4V (B2), 11.1V (B ) strictly according to the diagram, do not short-circuit intentionally!
Note 2: After the line is connected, it needs to be charged before output.
Note 3: When connecting three 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 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 poor battery use effect = 3 poor batteries use effect)
