Lipo temperature, safe storage?

[Wooders28]

After having my daily driver struggle to start after a couple of days without use in the subzero temperatures,this got me thinking.

Will my lipos (or the nicad/nimh for that matter) suffer being stored in the equally subzero temperatures in my garage?

They have been charged to storage and in a safe sack.

This is an interesting question..

I cant really comment on any negative effects that I have experienced, as I don't live in a climate that sees regular sub zero temperatures..

BUT, there is quite a bit of discussion out there on the www in regards to storing LiPo's in a fridge or freezer..

It may be worth your while to google "storing LiPo battery in a fridge" and having a read for yourself..

I live in Australia & in summer I HAVE to put my LI-PO'S in the fridge , as they will swell up .

I have killed a few before i did this . I do have nimh in fridge as well , In the 80's i used to do

the same with the nicad as well . My li-po's have lasted for some time now & they would die

in summer ( swelling up etc ) . When i went to use them , they didn't have the go like they used to

.

Maybe wrap them in some thing so they are not too cold ? as i'm not sure how low temp they

can handle .

I am in Scotland, the temperature hasn't dropped too far this year,only dipped to around -6c.

The bits I have read on the www are conflicting, some people saying that they store them in the freezer (most saying in the fridge,but I am only concerned about subzero).The lipo 'fact' pages say freezing will certainly damage them.

As my wife refuses to have them in the house because of a fire risk (after she disconnected one from the charger by pulling both the male banana plugs out of the charger as it was beeping!!!!) I may just sneak them into the loft until temps rise in a few months.

If your loft is anything like mine,

its just as cold in my loft as it is in my garage.

I store mine in an ex army Ammo box, under the stairs

I store mine in the garage, I live in northern Ontario(Canada) and I have had no problems with them freezing yet and I have been doing this for the last 3 years to no ill effect. It is regualarly minus 20+ Celsius and even colder some days, but if I'm going to use them I will bring them in to warm up first. I have 10 lipo batteries of varying voltages,c-ratings and sizes. So good so far

You've just reminded me that mine are sat in a bag in the boot of my car.

Better find another storage solution methinks.

Ukfox - under the stairs in our house consists of stacks of bog roll, and aerosols of polish and air fresheners,would be like guy fawkes night if there was a problem!

Dualdigger- puts my mind at rest that someone in the Arctic circle leaves them in the garage.

Guess I should not really worry about my RC batteries and worry about my daily driver battery!!

Hi You really don't want to store them in freezing temperatures.

Also when they are very cold they do not perform as well the chemistry don't flow amps through them as well in colder temperatures...

this is why it's better to keep they warm before going out in the cold to run something off a lipo pack.

[Wooders28]

It was more the storage part I was concerned about than running.

I am not sure of the make up of lipo's ,ie any liquid that can freeze and expand etc.Just to err on the side of caution,I have moved them to a slightly warmer location.

That's a good Idea.

warm them up to like body temperature before using them in the cold they will run better .
