I have read a lot of posts about the proper procedure for storing batteries under a partial charge and not storing them fully charged. What I haven't heard discussed is how long a time period are we talking about. Is it a couple of days or weeks? If you plan on flying in a couple of days is it ok to go ahead and fully charge them of should you wait until right before you plan to use them? Considering the price of batteries, I don't want to damage them and like everyone else, I want to extend the life of them as much as I can. What is the opinion of you guys on this?
