Storing Li-Po battery for over one month

Hello, I have a 3S 5200 mAh battery which I’m not planning to use on my drone for quite some time, maybe 1-2 months since I’ll be busy. I was wondering if it wont get damaged, since I’m storing at 3.8 V/cell, since last time I used a Lemon 3S 5000 mAh battery, it puffed up after being dormant for one month. Please let me know if I need to take any precautionary measures to story my lipo battery for this time period. Thanks in advance.

I have LiPo’s at storage charge for 5-6 months routinely without issue between 2 residences. Some are several years old and have gone thru this sleep cycle many times.
