Crashed in the Snow but My Drone Survived!

you can't really. 2 things, 1: what batteries do you have? 2: you might think getting higher mah batteries will give extra flight times but they will add weight, which will make your drone feel slow and unresponsive, and they might not even fit in the battery cage. what you can do to ensure the max flight time for the most amount of time is to charge them at the right amps. for each 100mah, you should charge them at 0.1 amps. e.g., 550mah battery: 0.5 amps. Also, store them at 3.8 volts if you want to make sure that they dont lose 'flight time' over the months. have fun!
