How to choose the right BMS

Attention

Illustration

Mismatched BMS Consequences

Lithium battery type

BMS type and lithium battery type must be in
one-to-one correspondence（Li-ion/Lifepo4)

1、BMS damaged,even bms and battery burn out
2、The battery cannot be fully charged and discharged

Number of battery pack
strings

BMS strings and battery strings must be in
one-to-one correspondence

BMS and battery burn out

Selection method
in experience

load maximum power÷(string number of battery×overdischarge voltage)×coefficient
Depending on the battery usage scenario, the coefficient value is also different
Please consult customer service for specific values

Specialty

Temperature probe(NTC) can detect the battery temperature in real time

Superiority

High-quality microelectronic components：precise and fast IC.Low resistance,high withstand voltage MOSFET.

Thermal silica,accelerate the heat dissipation.Ensure the smooth operation of the battery.

Low power consumption. The power consumption less than 50uA.

The PCB is coated with a high anti-corrosion, high impedance ESD conformal coating.

Preset interface,buckle cable,make the connection more convenient.

Balance cable connection

Preparation

Find the total positive and total negative of the battery pack.

Find B-/P- of BMS

Insert temperature probe (NTC) into the BMS

Welding

Note: When soldering, the balance cable cannot be inserted into the BMS

1、Connect the first string (black) of the balance cable to the total negative electrode of the battery, and the second string (red) to the positive electrode of the first string of batteries.The third string (red) is connected to the positive terminal of the second string of batteries,and so on, until the last string (red) is connected to the total positive terminal of the battery.Then check whether there is any cross in the balance cable or false welding.

2、After the balance cable is connected, do not insert the plug directly into the BMS.It is necessary to measure the voltage of the adjacent point on the back of the plug. (Regular voltage range: Li-ion: 3.0-4.15V/Lifepo4: 2.5-3.6V) After confirming that the voltage is correct, insert the plug.

3、Connect the B-(blue) of the BMS to the total negative of the battery.

Voltage measurement

measure whether the battery voltage（B+→B-)is consistent with the output voltage of the BMS(B+→P-).
If the two voltage values are equal, it means that the BMS is working normally.

Warning

1、BMS is a professional accessory. Misuse will cause damage. Please operate according to the instruction
manual or tutorial video.

2、BMS cannot be used in series or parallel

3、BMS does not support the use of reduced string numbers

4、BMS to work for a long time in an overloaded state is strictly forbidden

5、Lithium batteries need a dedicated lithium battery charger, other chargers cannot be mixed to avoid BMS damage and other safety hazards

6、BMS disassembled by the user，No warranty policy

7、BMS is damaged due to unauthorized modification of parameters,No warranty policy
