I don't fly my electrics as often as I probably should. This may lead me to a problem because I don't know the charge status of my LiPo batteries, and I have about a dozen of them in various sizes and shapes.
I guess I ought to take a look and see what's going on with them to make sure they are ok. I do have a balance gizmo for the different types so I can go ahead and hit them with the charger with the balance gizmo attached and see how that works out.
Of course, all this is done out on the outside concrete patio... with a LiPo sack.
