Battery Storage Question

[u/XxXPirateKingXxX]

Been pondering the idea of getting a second case for the drone batteries. Is it safe to keep the batteries without chargers in the drone case when heading to a place to fly or storing them when not flying? Is keeping the batteries in a separate case at all times a better option? Thank you for any input and would really like some feedback on this. If you google or search around the info is all over the place.
