  • Temperature

The BMPRO BC300 External Shunt and CommLink device provides wireless battery monitoring for high current BatteryPlus35 and J35 systems. It communicates with the units via Bluetooth and CAN BUS.  The addition of the BC300 External Shunt and CommLink to BP35 & J35 battery management systems allows high current loads to be directly connected to the battery via the BC300 External Shunt. This enhances the system behaviour with temperature monitoring of the battery for greater protection. It also provides correct battery information on the control screens.

BC300 maintains Time Remaining and State of Charge determination of the battery even at high currents and with directly connected loads. BC300 is designed for 12V batteries up to 800Ah in capacity. The shunt is rated for ±240A of continuous current and transmits monitored data wirelessly.
