Hard to beat the simplicity of these as a low voltage protection circuit in a small package. A few notes, the Relay does appear to be rated for 14v dc... I’m using it at about 19 without issue, but this feels like it’s worth mentioning since the spec sheet suggests it’s north of 30v for capability. The protection current is about 16ma when triggered, that seems pretty reasonable (see screenshot) from my fluke.

Works fine. Automatic on-off cooling bag. Starts when engine starts, stops when engine stop. 13.2V and 0.9V hysteres.
