Best way to store Lipos ??

[Jbreddawg]

Whats the best way for long term storage of lipos ? Like maybe up to a year ? we are in the process of selling our house and will be moving in a few months . Thats the reason I havnt been on here much lately . It's a ton of work to downsize after you have been in a house for 10 years !! Anyhow, everything is getting packed up and by the time we move, get settled, and I can get all my r/c stuff back out it could be up to a year !!
So, what should I do with my lipos ? I currently have 4 of them . Thanks !! Jerry

normally i keep that at half charged...but a year...hmm..id just charge them up fully and hope that it doesnt get below 3v per cell. best would be to just plug them into your charger every few months to keep an eye on the voltage.

Thanks, maybe I'll just pack the lipos/charger/power supply by themselves and keep them close by instead of in a storage facility. Thanks ! Jerry

Send them to me - I'll look after them... :)

I had to go out of the country on work and was told 3 weeks. I left all my lipos at 1/2 charge. I was gone for almost 3 months. When I got home, they had all puffed - the cell on top in every case.

I'd strongly consider selling them. I don't see them making it for a year in storage without them going bad. Either than or keep them and a charger handy where you can cycle them about once a month or so.

Then replace them when you get situated where you can use them again. They'll be better lipos than what you have now and possibly cheaper as this side of the hobby evolves.

Do you really think they wont last 3 months ? God I hope not lol !! I have had my trakpowers for over 3 months now and havnt charged them once yet !! I have alot of money tied up into these , I didnt think when I was buying them there would be a problem but now were planning on just getting an apartment once we move instead of another house right away until we decide where to settle . Most of our stuff is just going in storage for the time being. Were selling our house in So.florida and moving to jacksonville !!
How long do they sit on shelves before being sold ? Are they really that fragile when just sitting there ? I know they can be abused/damaged etc... but I didnt think if I put them away with a charge and pulled them out months to a year later they will be bad ?
I hate to sell them, I havnt even had a chance to use em yet !!

I know its been 3 months, but maybe you can still return them for a refund if they are still new?

I like the other idea myself. If it really looks like you will not get to them for more than three months, then sell them off and let someone else get some use out of them. By the time you get resettled and get back to running your R/C stuff Lipo packs will have evolved and probably gotten a little bit cheaper. Plus who knows what power or shape your lipos may be in at that point. Why gamble with that much money? If your on the move for a year then you can start fresh at that point.

Do you have a bomb shelter? Lithium batteries often explode spontaneously, often taking houses and cars with them. The best bet is to store them in some kind of sealed bunker.

[Jbreddawg]

Yes I actually do have one of the lipo bomb shelter things lol !! I just hate to part with my toys !!! Your all probably right though . I just know what stuff goes for second hand, even if it is still brand new .

This directly off the label on my FlightPower 4900 2S Evo 25 pack:

STORE LONG TERM AT 3.4V PER CELL

AVOID UNNECCESSARY CHARGE CYCLING

This is the kind of straight talk I want to see.
