Split charge relay?

[Anguz]

My works van has quite a lot of extra circuits... water heater working lights beacons etc
There is no separate battery for these, but there is a relay somewhere that drops them off before the battery goes too low to get me home?
Dunno where they have hidden it, but I would like one for one of my vehicles

Any idea what it is?

no reason you couldnt use a battery protect relay to disconnect individual circuits rather than the whole electrical system.

All I want to be able to do is drop a 10a socket off.

Thinking about it, would be easy with an arduino and a suitable relay
