Briefly Introduction with this BMS :
This smart Lithium ion Battery BMS was designed for Electric vehicle battery which can work for 10S to 15S Lithium Ion Battery .charge and discharge current can be reach 30A constantly .
This Type BMS has such special Functions except the basic protection function ,it will have such functions as below :
1) Parameters can be set flexibly through the communication port such as protection values of charge and discharge , current ,BMS can read the battery information even it’s current reachs to 30A .battery information can be read such as Battery capacity ,Remaining capacity , RSOC, Battery voltage , temperature , Current etc .
2) With full set of protection functions :Over-charge ,over-discharge,over-current , short circuit protection,Temperature protection ,all protection delay times can be set based on your demand .
3) With standard UART communication interface .
4) Various of working modes which can adjust the current consumption of stand-by or works .
5) With sleep mode .
some Protection parameters can be set based on your demand , here is just a specification samples for your reference

Other series cells will have the similar connection methods as below
This PCB can be adjusted flexibly for your battery application for such series :

It can work normally by setting the over-charge ,over-discharge protection value ,and Series Numbers of your cell etc to let your adjustment work correctly without problems .
Reminds : We will send the detail connection drawings to the client with this product if client needs and this BMS will includes all necessories connectors with wire to make sure client can connect it easily . please follow up it correctly to avoid of any mistake ,above connection is only for simple explaination purpose .
1)Do not apply the PCB which beyonds the specified criterias as above :
2)Sometime , the battery may not discharge when connected this PCB , please connect it to the charge and it can recover to the normal status .
3)The PCB may not work normarly When Mixing cells which were over-discharged or over-charged ,
4) Do not shock this PCB with big static even though the PCB has been designed with anti-stastic protection function.
