Anyone had similar problem. My battery monitor fluctuate around 0.5v. Inderstand it fluctuate but shouldn’t the battery monitor average out the voltage to be presented?. AThat is a small issue but the main problem would be when every ilI plug in new battery, the monitor sometime will be off by 1volt. And always I have to update the correct voltage in the battery monitor. Is it because PM02 is a bad battery sensor? Or my sensor is spoilt? Is there a better more accurate sensor? How about Mauch?
