14.8V / 16.8V 20A Bms Circuit Board for lithium LicoO2 Limn2O4 battery

Precautions:

The lithium battery protection board cannot be used for lithium iron phosphate batteries, xenon lamps, hand drill battery packs, electric fish machine battery packs, electric bicycle battery packs, children's car batteries, motors or products with motors, 1W fisheye LED lights.
For products with a current above 3A, the battery discharge rate should be above 3C.
Rate formula: 1C rate battery, 2000 capacity equal to 2AH*1=2A working current 3C rate battery, 2000 capacity equal to 2AH*3=6A working current

• Strict wiring OV(B-), 3.7V(B1), 7.4V(B2), 11.1V(B+) do not intentionally short circuit!
• After the line is connected, it needs to be charged first, and then there will be output
• When connecting 3 groups of batteries in series, please ensure that the voltage of each group of batteries is the same, if not, please fully charge each group of batteries separately and then use them in series. During the discharge test, the battery with the fastest voltage drop is the poor battery.

A note:

• don't mix good batteries with bad batteries!

• The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of 2 good batteries + 1 bad battery = the effect of 3 bad batteries).

• In use, the battery will heat up, that is, the battery rate is not applicable. In this case, if the battery cannot be used for a long time, the battery will be damaged quickly.

• Applicable products: massager battery pack, LED light backup power supply, 12V electronic products, solar street light battery pack, monitoring backup power supply, and other products.
