la-boy,

That's the point I was trying to make. Sorry if I was unclear. Don't trust you meter installed on your cart. Take the readings at rest often and compair them to your meter and go from there. Now that you have them all charged up, take a reading with your DMM and compair it to your installed volt meter. Drive it for a while and take the readings again and compair the 2 until you are comfortable with your volt meter compaired to your DMM. You don't want to take them down to 46v very often.

See if you can return that POS Chinese meter and get one made by Curtis.
