If you love your drone, and it has been sitting on a shelf for a while because it's too cold, rainy, windy, or you are a bear and have hibernated for the winter, it's time to do your monthly cycle on your batteries.
Lipos dont like to be left unattended for long periods of time. No, they dont get lonely, they just like some attention in the form of being used. If you cant fly, then simply charge the battery up to 100%, and either hover it down to 50% or lower, or the less desired method is to let it sit on a table with the props off until the battery drains down, which could take a while.
If you leave your batteries all winter and dont take care of them, dont expect them to be their lively selves again in the spring. You might be looking at replacing one or more if you let the voltage get too low.
A word to the wise, and I hope everyone is having a good new year.
