I would say they will be fine. I have been using lipos since 2004 and have never had an issue with quality batteries. Some disagree due to what they have read online but almost every case of a lipo fire, swelling, or rapid discharge has been due to cheap packs that had a known defect or were abused in one way or another. These batteries self discharge what's not to love? Now if I had batteries sitting for 4 months without use I would put them at 3.8v per cell, just a storage charge.
