When using CAN bus batteries such as BYD and Pylontech with inbuilt BMS, is there a mechanism to have an effective "charge enable" and "load enable" signal from a Venus device to shut down external charge sources and loads before imminent battery shut down. Use Relay 1 and Relay 2.
An example might be a vessel where non-essential loads could be shut down before battery shutdown. Or disabling an alternator charge source.
Might this be part of DVCC? The system would, of course, have a BMV device to know net battery current.
