    There really not that bad if you make sure to, Charge in a Lipo bag and store them in one when not in use is what I do. Keep a close eye on them when charging, and read the manufactures instructions of usage / charging ect ect. And you should be just fine, nihm packs are not pretty when they go up in smoke/fire, I'm sure there are some on YouTube. So there is a risk to charging really any battery IMO.

    ^^^Looks like the NY Metro area is checking in.
    Should you charge and store in a fire-safe bag or container? Of course. It doesn't matter which chemistry you use - there is a LOT of energy stored in today's batteries. Example: I threw a freshly-charged transmitter pack (8 AA NiMH batteries in a holder) into my leather briefcase one evening at my office. I soon started asking "What is that burning plastic smell?" It turns out that the contacts for the holder had shorted on something in my briefcase and the heating only stopped when the coiled contacts on the negative ends of the cells flattened due to the heat and meted totally into the plastic of the holder.

    Treat any battery with respect, care for it, don't leave it alone when charging, and you'll be fine.

    I always put mine in store mode when not in use, of course you just need to read the manufactures recommendation on what they call for? Some on here I'm sure will say 24hrs to 48hrs then after that they will put in storage mod if not using, I guilty of doing this a hand full of times myself. Still have the house and the r/cs and the packs are 100% like new.

    I know when I bought my Lipo's it said that they are poisonous and I am wondering what is Poisonous. Is it the fumes or is it the liquid that is inside them.

    hhmmmm..... no expert here, but, don't think there's a liquid inside the batteries..... I believe most batteries are poisonous if ingested. Just MHO.

    No liquid I'm aware of but the metals and how they react are poisonous as are the fumes if they were to start on fire (well anything that is on fire gives off poisonous fumes ). Why ask? Sure hope you don't plan on eating one or giving one to the dog for a treat.
    Don't be scared of lipo batteries. Sure there are dangers but many times we get too focused on the small percentage of mishaps and videos showing fires that we disregard the majority that have no issues at all.

    Yes, I started out with electric helis that use lipos. I was a complete noob but I never had a problem with my batteries.

    What happens to lipos if they get wet?
    (From driving in snow, wathersplash etc).
    Is it dangerous to try charge them or are they already smoked and ready for recycle?
