title_body: How long can a LiPo pack be kept fully discharged before storage charging?
upvoted_answer: The most appropriate answer I could find comes from this study which states that a charged LiPo should be returned to storage charge if you do t plan to use it within the next 12 hours, and leaving it longer will cause a buildup of damage. The study is very interesting, though it may not explicitly answer your question I recommend giving it a read.
