Digital amp meters
I have these digital ammeters in two of my Electrathon race cars and they work great! In Electrathon racing, we constantly monitor the amp draw on our batteries during a race and the large digital numbers are easy to read at a glance. On some race courses, the cars (and everything in them) are subjected to some pretty severe vibrations. So far these ammeters have held up and had no problems.
