Will I destroy my LiPo's?

[RC-NUT]

Hey guys,

I picked up a brand new pair of Turnigy 3s 40c 5000 LiPo's for my Savage. I charged them, balanced them, and then mother nature took over here in the North East.

Due to endless snow they have been sitting in my truck fully charged for 2 weeks. With more snow in the forcast they will most likely be sitting for a long time.

Do I need to discharge these and charge them 50% or can they hang on with a full charge.

Thanks!
