9v x5 (45vdc) battery board

[Freq Band]

I came across a battery pcb, and thought I'd point to it.
I'm not associated with the seller.
....just thought it might be of some use.
I have not tried it.

Cool.  Now cost on running batteries in a 180V remote amp, maybe 200 hrs use if the old manuals are correct....ouch.    Nice to have options.
