You should have a ESV, Expanded Scale Voltmeter. This meter will put about 250ma to 300ma load on your battery. That will give you a better check of your battery. A loaded battery will read different than an unloaded battery. I like to check my batteries before and after each flight. This gives me an idea how much is being used, and if you see more current drain than normal, a heads up on a pending problem.
