Click to enter the APP and select the corresponding BT.
PS: Before entering the APP, you need to plug in the temperature control NTC. To confirm that the protection board has been activated and working, users who have purchased the battery display board (key activation) only need to press the switch on the
battery display board to activate the protection board. The first time it needs to be charged and activated.Enter the APP interface, you can see the corresponding BT serial number. The serial number is the same as the serial number posted on BT.
Click the BT serial number to enter the real-time status interface.
You can see the real-time voltage, current, the percentage of battery capacity remaining, the MOS state of charging and discharging, whether the balance is on, etc.
Enter the parameter setting interface, you can see five major sections:
Protection parameters
Battery core characteristics
Collection board settings
Temperature protection
Charge and discharge control
Note: To ensure the stability of the data, it is not recommended for non-professionals to set this parameter. To set parameters, you need to enter the initial security password 123456
In the protection parameter interface, the protection values of voltage and current can be set.
In the battery cell characteristics, you can set the total capacity of the battery, the remaining capacity, and the balanced opening conditions. Set the sleep time to 65535S to cancel the sleep function.
In the acquisition board setting interface, it needs to be set together with the hardware device.
In the temperature protection setting, the protection temperature of charge and discharge can be set
On the charge and discharge control interface, you can switch the charge and discharge MOS tube, and you can reset the password
BT module is 6USD per pcs ,UART tool box is 8USD per pcs
If you buy our smart bms, we will offer you free software to download for cell phone and PC

FAQ
1.What is the common port and separate port? what is the difference?
We take 13S48V16A BMS as an example, common port 16A means your charge cathode and discharge cathode are connected in the same point end(our P-), charge cathode and discharge cathode are used in the common connectionport, so the charge current and discharge current are the same 16A. while the separate port is separately connected by charge cathode (C-) and discharge cathode (P-), so the charge current and discharge current are different, discharge current 16A, charge current 8A.
2.What is the balance function?
The working principle and function are as followings, when your one cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4 upto (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will starts a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage(Li-ion 4.25V, Life Po43.75V)BMS starts off power protection, all the other cells are all in stop of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then balance can not be functionning well
3.The relationship between Battery capacity and BMS current?
There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.
4. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge.Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
5. What current BMS should I choose ?
Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 16A for below 350W, 25A for below500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one inall, continue current shall be higher than current limitation in Controller.
6. Whether my BMS damaged?
if you want to judge if the BMS is damaged, please take the folowing steps, to test if each cell voltage is the same with voltmeter? if the cell voltage difference is over 0.1V, the fault is displayed that it cannot run far, no power supply at thestart range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displyed as no charge, no discharge, no discharge while the battery has voltage.
