EV - Electric Vehicle Compatibility - 3 reasons to install a BB instead of direct cabling / relay:  Underneath the bonnet of EVs is the positive and negative 12V terminal that leads from the high V -> low V DC DC converter to the 12V battery. There is usually a 12V positive busbar and a 0V negative post. One of these positive feeds leads to the 12V battery. The 12V post that leads to the 12V battery would be where you install the BB along with the common negative post.  The high voltage to low voltage DC DC converter shall likely be itself current limiting. However, the vehicle has uses for this current, albeit, not all of this current all of the time. 

The Sterling 12V to 12V DC to DC battery charger is able to charge in both directions. Provided there is over 13.2V on the leisure battery (13.5V if lithium) and the starter battery is below 13V the BB shall allow approximately half current (~20A) to flow back to the starter battery up to about 13.4V (float voltage). It simply allows the starter battery to remain topped up when there is surplus energy in the domestic battery. This feature will NOT drain your domestic battery - it simply takes surplus. Once your alternator / engine turns on or you provide the BB with an ignition signal the BB reverts to normal charging of the leisure battery.  This mode can be disabled, but is on as default.

This is ideal for allowing the starter battery to remain topped up when you have solar / wind / charger - charging up your leisure battery.
