Simplex 4010-9820

Anyone have a Simplex 4010-9820 Meter Module? Seeing references to it in many places but no actual pictures besides drawings in manuals, if anyone has any info or images of them I’d appreciate it.

I’m not convinced this ever came to market. I’ve never seen it out and about. It is a neat idea though. If they do exist out there I’d love to see one.

What would such a module even do?

It looks like it’s meant to be a continuous monitor of the batteries themselves. It’s unclear to me if it regularly load tests them though.

i’ve seen manuals, it’s an analog voltage and ampere meter like what you’d see in a 2001 pretty much, would’ve been cool af if i could find one.
