Giới thiệu Bảng mạch bảo vệ pin lithium 18650 3S 12V 8A 11.1V 12.6V tại Lotte Market
note:
For products with a current above 3A, the battery discharge rate must be above 3C.
The magnification calculation formula: 1C battery, 2000 capacity is equal to 2AH*1=2A upper limit working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A upper limit working current.
In use, the battery will heat up, which means that the battery rate is not applicable. In this case, it cannot be used for a long time, and the battery will be damaged quickly.
description:
3 strings (for 3 18650 batteries or polymer lithium batteries in series combination)
10.8V (rated voltage of polymer battery)
11.1V (18650 or 3.7V lithium battery rated voltage)
12.6V (Voltage after fully charged lithium battery)
Discharge 10A (refers to the upper limit discharge current limit)
Note 1: Wiring 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) strictly according to the diagram, do not intentionally short-circuit!
Note 2: After the line is connected, it needs to be charged before output.
Note 3: When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are not the same, please charge each group of batteries individually and use them in series. During the discharge test, the battery whose voltage drops fast 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 = 3 bad batteries).
