Automatically re-connecting low-voltage cut-outs for 12 and 24 volt battery systems

In a previous post I described a simple circuit that provided a low-voltage cut-out that could be used in a battery-operated system – see the article “A latching low-voltage disconnect for 12 volt lead-acid and lithium batteries”. That circuit – intended mostly for lithium-based batteries – required manual intervention to “reset” the device, intended for those situations where you wanted to provide manual intervention in resetting the circuit to prevent causing harm to the battery – and maybe the gear connected to it.
This circuit is different from that described in the link above, intended mostly for lead-acid based systems where an automatic reconnect of the battery is required upon application of charge current.
