Product Description

 

1) This PCB board has adopted high end Battery Managment IC chips  and Mosfet to obtain more stable and reliable working performance during charge  and discharge 

2) Working current is 40A constant current also by Apply low resistance Mosfet  

3) With weak electricity switch to control the discharge to prevent the drain of current during work-off time 

4) With charge port protection function , no fire spark with occur when conenct your charger to this PCB board , it will be more safer for our clients . 

5) With Balance function and over-charge ,over-discharge , over-current protection ,short protection etc .

FAQ

A . How to choose a suitable BMS for your Battery ? 

   1) Voltage : It depends on these factor you should know about your battery  ,the series number of your battery , for example , if you battery has 16S in series Connection,you should use 16S Battery BMS . 

   2) Battery Types : there are a few different Battery types in our Maket ,such as Lithium Ion Battery with 3.7V typical Voltage , and Lifepo4 Battery with 3.2V typical voltage , also some LTO battery with 2.4V typical voltage , each Battery has different protection voltage , and their PCB should be different . 

    3) Current : How much constant current will be suitable for you ? it depends on two factors mainly , the first is your motor power  and the second is your controller limit current . client should consult us before buying for current issues . otherwise , we will take no responisibility . over-current can have the possiblity to damage our PCB easily 

 

 B. How to make connection with Battery 

      We will send a connection electronic file to you for the BMS connection , you should read carefully on connection instructions of us . any wrong connectim will damage our BMS . 

 

C . How can I get the software for some type of smart BMS ?

       Client can download the software directly from our appointed links without problems . buyer just need to install these software in your PC computer or your mobile Phone . 

 

D. How about the Quality assurance with your PCB board 

      Normally we will offer 12 months quality warranty time for our Clinet , we can repair it by free of charge and offer some new replacement PCB to our client if the BMS problems occured from any design and Production defect . any other reasons which damaged our PCB board by our client , this serivce will not covered . But we can also offer the repair service to our buyer and charge some necessary components fee .
