Universal BMS from 8S to 20S, 400A peak, programmable with Bluetooth, for Li-Po, Li-Ion, LiFePO4, LTO batteries
Prices:
8-20S BMS 400A without display - 330 BGN
Display - 50 BGN
The BMS is universal - a battery from 8S to 20S can be connected. Follow the corresponding wiring in the pictures!
overcurrent protection, recharge, short circuit, output current limitation, and balanced (balanced) cell-by-cell charging
WIRING DIAGRAM: See photos
Instructions: A hall connection can be soldered to the back of the display (if a display is ordered)
Click Hall Speed Measurement
After connecting, you need to connect the settings of the Bluetooth parameter, to change the tire diameter, to calibrate the speed.
Power supply of the BMS, instruction:
You must first connect the blue silicone wire B to the protective board- to the negative battery line.
Then connect the balance cable, be sure to follow the corresponding battery level diagram, to connect. Once the balance cable is connected, use a multimeter and measure the sequence of volts if they come out correctly.
Once all the wires are connected properly, the red cable and the black cable of the quad socket are connected with a voltage of 3-5V (either from an additional 1S battery or from one of the series of the already made battery, and the protective board can be switched on after 1-2 seconds. A non-stop button is used to switch on, as for switching on and off the button must be held until an audible signal is heard.
Activation of the BMS can also be done by turning on the charger.
Red - positive pole (+)
Black - negative pole (-)
Peak current per discharge - up to 400A
Charging current: up to 50A
Balance current: 100mA
Charging and discharging port
Size: length 14cm. width 7cm. height 1.7 cm
Single cell voltage: detection range 1V-4.6V, accuracy less than 5Mv
Recharge and Recharge: Protected
Short circuit protection: short circuit protection current can be set
Bluetooth connection: for Android and IOS
Applicable battery:
8S to 20S version:
8S to 20S version: 8S to 20S Li-ion battery; 8S to 20S Lifepo4 battery; LTO battery from 8S to 20S
Coulomb counter: accurate calculation based on current versus time
Remaining battery capacity, the error range is less than 5%
Power consumption: 3mA , 1.5mA during standby
Temperature sensor - 2 pcs. (If they are not included it shows – 30°)
Display size: 93mm. h 70mm. x 23mm.
Display power supply - from 24V-150V.
If they are not - load them separately and then use them in batches.
To check the condition of the battery - if the voltage of a given / certain series fall faster, it is weak in these series / damaged battery.
It is not good to mix old or weak, or different battery models together!
The state of the assembled battery is relatively equal to the state of the weakest element in it!
