Don’t some radios have a small parasitic drain, for model memory and such? Thought I had seen this mentioned in some of the radio threads. Guess it would be OK as long as you routinely use and more importantly charge... but what if you don’t for a while, for a variety of possible reasons, some unexpected/unplanned? Believe most suppliers caution against even leaving a lipo plugged into the car/esc due to small parasitic drains.
