24v Voltmeter

I’m refurbishing my boat, and would like to update my old battery volt meter with a newer one that has a digital readout. The existing hole in the panel where this will sit is 2″ round. I’ve found 12v digital meters that are 2 1/16th, and 24v meters that are too small, but can’t find a 24v digital meter that is around 2″. I am assuming that to monitor my trolling motor batteries, which are hooked up to make a 24v system, I need a 24v meter. I can’t understand why it’s so hard to find this thing. If any of you are using a battery meter for your 24v trolling motor setup, could you please let me know what you use and where to look to find one? I could just keep using the older meter I already have, which just shows an arrow that points to the voltage, but I like the idea of getting a very precise reading from a digital display. Thanks.

does this help??

Funny timing, I just took my battery meter out of the boat yesterday and installed a 12 volt outlet and light in it’s place.

No need for the meter since most trolling motors have a built in gauge already on them.

Good point B-man, but I’ve got a hole in the panel that needs to be filled, so I figured a cheap update would be this meter. The one on the trolling motor can’t be seen from as far away.

Thanks Iowaboy. That digital one you listed looks like what I need. Is 52mm basically the same as 2 1/16″? The hole in the panel is 2″, or 2 1/16th, and I need to assure the one you listed will fit.

a hair under 2 1/16,52 mm converts to 2.047 inches,,should fit,may have to file a tiny bit out.

Thanks
