Monitor all connections direct to battery
The BMPRO BC300 External Shunt and CommLink provides additional battery monitoring for your BatteryPlus35 and J35 Power Management Systems, connecting directly to battery via the BC300 External Shunt. This enhances system behaviour with temperature monitoring of the battery for greater protection.
The addition of the BC300 to the BatteryPlus35 and J35 Power Management Systems allows high current loads and external charge sources.
The BC300 also provides your BatteryPlus35 and J35 with additional information on battery usage so your displays such as the Trek, JControl and JHub are always up-to-date on battery Time Remaining and State of Charge.
The BC300 External Shunt and CommLink communicates via Bluetooth and CAN bus. The BC300 External Shunt is designed for 12V batteries up to 800AH in capacity. The shunt is rated for ±240A constant and 300A peak.

FAQs
A BC300 is required for any load or separate charge source going directly to the battery.
Below is a list of items that are fitted directly to batteries in caravans:
Inverters (of any size), diesel or gas heaters, air compressors, portable solar panel, DC/DC chargers (in any brand), additional fridges, Wi-F, satellite TVs, additional high amp 12v plugs (Anderson plugs, 50amp, 80amp, 100amp, 150amp), additional lighting, electric steps, slideouts, electric water pumps electric jacks, winches.
Both units can communicate to each other 25 meters away from one another in open sight.
If your Power Management System has an inbuilt solar regulator, unregulated solar panels should connect directly into the J35/BP35 solar input terminals. There is no need to install an external regulator between the solar panel and the J35/BP35.
If you want to add an additional regulated solar panel or a blanket panel, it needs to go directly to the battery, and would require a BC300 fitted so that your battery monitor (JHub, Odyssey, Trek, RVView, JControl) reads correctly with the coulomb counting.
If your J35/BP35 is not solar compatible (J35A and some earlier versions of the J35B, BatteryPlus35-PM), you can install your solar panel directly to the battery through an external regulator. If you want your battery monitor to see the solar charging current at the battery, you will need to also connect the negative through the BC300 shunt.
