panel meter

At long last, I found modern analog DC voltage panel meters or gauges to put in my "portable" power tank.

Visited, for the first time, A-1 Electronics on North Queen. Big place. Probably bigger than Active Surplus; but not as much as Sayal. A bit of a jumble with some narrow aisles. Still, they found everything that I wanted. Good prices too. The same kind of meter at Efston is $40! I walked out of A-1 with 24 green LEDs, some wild red-green flasher LEDs, a gaggle of resistors, and the 2 Hopesun meters for the same amount of money...

I will put a momentary switch on the gauge circuit so that I can quickly check power in the 12 volt gel batteries.
