Should Lipos be discharged for winter storage or…


...can they be stored in a charged state?

I would think it would be safest to store in a discharged state, however, some of my metal packs, esp Kans, seem best stored in a charged state.

I found stored charged Kans did best when it was time to get back out this past spring and do some flying.

Of course these are vastly differing battery technologies, I am just curios to hear what others have found.

Half


Half discharged is the best state for long term storage.

Most manufacturers say that they should be stored at ~50% charge.
Some people say that storing them fully charged significantly shortens their life.

I would just fly them down at a normal discharge rate and nominal voltage of 3.7V per cell .

I use a single drawer metal parts bin to hold all my LIPOs.

First, thanks for the quick response gentlemen, much appreciated.

The Triton is now fired up and the discharging has begun.

I am going to discharge close to the nominal.

I think storing these packs in a metal container or like, is a darn good idea, just to be on the safe side.

I do all my charging of lipos in a large Croning ware pot with a lid. I may just keep em all in there for storage over the winter.

Cheers

So if the lipos were to go on fire within a metal box, the box would become molten hot and ...... hmmmm. Shouldn't they be stored in sand or a material known to snuff out fires?

It is a cruel reality up here in the “north”.

I do have a GWS Cub (370 mod) with skis and lights though.

Some of the belly landers I have are ok in relation to snow, as long as it is not to cold.

Thank goodness for indoor flight (fright) night.

I figure the less one knows about winter the better. If you can avoid it altogether, that is optimum.

Often during the winter months I see pics of guys out flying in Florida etc… sunny warm…I get a case of South envy.

Snow is for pictures on Christmas cards.
Ice is for putting in drinks.
Sleet is for making crushed ice flavored drinks.
Cold Air is for putting in air conditioners in the summer.

And you thought we were dummies.......

Did I think you were a dummy hoppy?

That is a rather strange thing to post in a thread about Lipos.
