Heltec BMS 96V System Relais Smart BMS 25S-32S 500A Lipo lifepo4 bms mit BT UART RS485 KÖNNEN für Gabelstapler/Solar Energie Lagerung
Above 32S BMS Customized
Pls Contact us if you want to make above 32S battery pack
Suggestion
Below 200A choose 2 Relay is enoughabove 200A choose 3pcs relayif used on like Heavy Truck start up. choose 4pcs relayif you want to USE ON RS485 OR CAN , you need buy a Serial port module as below:

The scheme of control relay
Compatible with battery pack.App modifies parameters, supports Li ion and lifepo4
Products schematics
It can control 2-4 relays to control power off, connect with Hall sensor and shunt, and charge and discharge different ports.
DC relay
Customers need to equip their own relays, select the required current, and support the choice to cut off the positive or negative wire.Various mainstream relays can be used, with convenient selection and more stable use.
3s-4s is collected by shunt and 6s-24s is collected by Hall sensor.
Cables mark
Each cable has a corresponding mark to facilitate customers to identify the corresponding function
Bluetooth module
Bluetooth transmits signals, mobile phone APP receives information, and the effective distance is within 10 meters.
APP
You can view the battery status and adjust the BMS parameters by Phone Bluetooth APP. If you don’t know how to use it, please contact us to get the English manual.Note: iPhone can only view parameters but cannot adjust parameters.
Balance Function
After setting the battery voltage difference between 0.02V-0.05V, it will automatically turn on, and the balance current will be 60mA.*This balance power can only play an auxiliary role. If the actual deviation is large, a special balance instrument is required
PC software
Our development and adaptation of the PC BMS PC software supports monitoring parameters, modify the configuration and other functions. Notice: It must be used with UART or RS485 module to USB . Please contact us to purchase if you need it.
NTC
The product has 3-4 temperature sensors with a length of 500mm. It can collect current battery temperature information.
