1. Smart Relay BMS *1set. (Other parts according to your needs)
2. Anti-static bag, anti-static sponge and corrugated case.
32S 100A Split port BMS include:
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.
It can control 2-4 relays to control power off, connect with Hall sensor, shunt, and charge and discharge different ports.
The relay is a main circuit switch. You can choose different currents, but the maximum current does not exceed 500A. It is recommended that the working power consumption be less than 500mA. BMS only provides 12V control voltage to control the introduction of relay. (Current relay power consumption: 250mA.)
Our development and adaptation of the 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.
The product has 3-4 temperature sensors with a length of 500mm. It can collect current battery temperature information.
