4S 12V LiFe Po4 Battery 3.2V Power Protection Board "Common Port" 30A with Temperature Protection Equalization Function, Overcurrent Protection, BMS (10004316)

BMS is for battery use, different strings are not compatible.

E.g: 13S BMS, can not be used for 10S battery, can only be used on 13S battery.

Description:

Range: nominal voltage is 3.2V lithium battery (including 18650, 26650, polymer battery).

Function: Overcharge protection function, over discharge protection function, over current protection function, short circuit protection function, battery balance management function, temperature protection function.

Temperature protection

The 3-7S is equipped with a mechanical temperature sensor, which can realize functions such as overcharge and discharge temperature protection, effectively improving the safety of battery use, and solving potential safety hazards caused by thermal runaway of batteries.

1 x 4S 12V LiFe Po4 Battery 3.2V Power Protection Board 30A

Operation:
1. The cable starts from the black thin wire connecting B-, the second wire (the thin red wire) is connected to the positive pole of the first battery, and the positive pole of each battery is connected in turn until the last red wire is connected to B+;
2. After connecting the cable, do not insert the plug directly into the BMS. Measure the voltage between each two adjacent metal terminals on the back of the plug. If the voltage of the terpolymer battery should be between 2.8V and 4.2V, the iron-lithium battery should be between 2.5V and 3.65V.
3. After correct wiring queue and voltage confirmation, insert the BMS socket.
4. The protective board B line (blue thick line) is connected to the negative pole of the battery pack.
5. After the wiring is completed, measure whether the total voltage of the battery pack and the total voltage passing through the BMS are equal. If they are different, check again according to the above wiring queue.

Tips:
The battery pack protection board, which is a semi-finished product of electronic products, is a wearing part in case of wrong use. If you don't understand how to use it, please read the manual carefully or ask the customer service. Any wrong use will burn out the front-end sampling resistor. We will not accept such disputes of customer damage. Please do not buy if you mind.
