How to choose the right BMS

Attention

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

BMS Connection Steps

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

2、Measure Voltage:After the sampling cable is connected, Pls measure the voltage of the adjacent point on the back of the plug. (Normal voltage range: Li-ion: 3.0-4.15V/Lifepo4: 2.5-3.6V) After confirming that the voltage is correct, insert the plug.

3、Get start:1)Plug the sampling line into the BMS ; 2) The BMS is automatically activated when the power is turned on.lf the cable is discon’nected or manually removed and plugged in during the use,it needs to be powered on again to activate.
