After reading this thread I decided to pick on of these meters up myself. Would it be a big drain on the battery if it is connected to always be on? These meters can be picked up on ebay or aliexpress for $3 or less shipped.

I am not sure how much current it draws, but I would think it would drain the battery down in less than a week. It sure needs to be put on a key switched power source in my opinion.
I agree with the others, connect it to a switched supply to prevent parasitic battery drain. Always try to avoid constant battery drains. However small they may be, they do add up over time and will lead to shorter battery life. If you must connect it directly to the battery, add a push button switch in series as you probably don't need a constant voltage reading.
Thanks for the advice. I am using a marine rocker switch for my LED lights. I believe I should be able to connect to the switch and have it power on the voltage display when the switch is in the on position.
