LiPo charged long ago. "safety issue"?

[Jachto]

Hello!

I bought a new set of Saddlepack LiPo's (Intellect IP 4200) about last august. I charged them once and drove around, then i broke something i think, and i put the car away. Until now when i remembered that i din't discharged the battery or anything.. they have just sat there in the car...

Is it dangerous to charge them again? I have a LiPo safetybag, so thats alright but stil...

PS: So tired right now, not focusing on spelling. Hope you understand!

Thanks
