• Remarks :
  A. Firstly ,Please connect two bold wires from B- port of the BMS to the negative port of the battery pack .(B- wire should be as short as possible ) ,then connect these voltage detection wires (Please take off these wires from the BMS before connecting these wires to the battery to avoid any connection mistakes )
  B. Second ,Please start connect these balance wires to the Battery system from BC0 ,Black thin wire should be connected to the battery negative , and the second wire -white wire BC1 should be connect to the positive port of the first series cell . BC2 should connect to the positive port of second series cell ,and BC3 wire to the third cell’s positive ….connection in this way in order one by one till to the last cell postive port
  C. Third . After connection of these balance wires finished , please measure connector voltage from each Neighbouring wires ,the voltage between each neighbouring wires for Li ion battery should be less than 4V and for Lifepo4 Battery should be less than 3.5V ,after confirmation of these wires connection order , you can plug cable connector into the BMS .–wrong connection order will damage our BMS surely . please be carefully with this step .
  D. Finally , connect C- wire as negative of charge and discharge , B+ wire as positive of charge and discharge , those wires should
  use bold wire to make connection for large current distribution purpose . then please comparing the voltage from the BMS and voltage directly from the Battery to see if they are the same or not . if they are the same value . your connection is correct , otherwise terrible things will happend !!!
  9) Precautions for use
  1. When in use, design parameters and work conditions must be followed, and the parameters in this specification must not be violated, otherwise it is easy to damage the protection plate, and then damage the battery pack.
  2. When in use, there should be corresponding electro static-free measures for testing, installation and contacting with the protection board.
  3. The charging port can withstand the specified DC voltage. If the charger is higher than this voltage, it cannot guarantee that the protection board will not be damaged. Please use the charger according to this specification. It is better to choose the charger with the function of closing the trickle current at the end of charging current, so as to achieve double security. Chargers without trickle current closed are designed for lead-acid batteries and do not work with lithium.
  4. When in use, Pay attention to the electric lead, electric soldering iron and solder splash. Do not enable them to touch the components and parts on the circuit board; otherwise the protection board may be damaged.
  5. The maximum discharge current is the maximum current that lasts for a few seconds. During the test, it cannot last too long to avoid overheating damage of power MOS.
  6. When assembling the protection board and the battery pack, do not place the heat dissipating aluminum plate close to the surface of the cell. Otherwise, the heat will be transferred to the cell, affecting the safety of the battery pack.
  7. If abnormal conditions occur during use, please stop using it immediately, return it to the original factory or ask professional maintenance personnel for maintenance.
  8. If it is a split protection board, it is forbidden to use P- as a charging port. Because P- is used as a charging port, the battery pack has no overcharge protection. It is forbidden to use C- as a discharge port at the time of splitting
  9. It is forbidden to use two or more protection boards in series and in parallel.
  10. The protection board has already done a lot of reliability tests, the reliability is far higher than the general protection board on the market, and the process of the cell must be ensured at the same time, so as to reduce the occurrence of combustion as much as possible.
  11. This BMS does not have 0V charge function,the battery performance will be deteriorated seriously and even dead
  12. In order not to damage the battery ,user should charge the battery periodically when the battery does not work for long time ( battery capaicty are more than 2Ah , storage time exceeds 3 months) ,after discharge compeltely ,please charge the battery in time within 12 hours to prevent the battery from discharge to 0Volt due to self-current consumption with the battery . client should label the battery with clearly battery manitenance instructions to improve the battery heathly .
  13. please do not make reverse charge as this bms does not have anti reverse charge function .any reverse charge will damage our BMS probably
  10) Safety Precautions:

  Our company is committed to improvement of quality and reliability, but in general, there will be a certain probability of failure in electrical components and parts, with different environment and conditions, the durability will be different. When in use, the lengthy design is adopted to avoid overload abnormal fever, smoking, and even casualty, fire accidents, social damage, etc.
