Where is thread on battery storage?

Hi all,

I read the sticky "Everything you need to know about Li-Po batteries", but didn't see any information in it about storing Li-Po's.

Also read the sticky that contains hundreds of images of Li-Po's on fire, and also read the sticky about how to buy Li-Po's.

I have a Triton charger and also have a Thunderpower balancer to prepare the batteries.

Is there a particular thread that details exactly how Li-Po's, NiMh, and NiCd batteries should be stored for the winter?

Thank you,

Chuck

Storing Lipo's

Sanyo spec is 20-50C
Motorola recommends not to exceed 45C and states that lower temperatures give a longer cell life.

Hi everydayflyer,

Thank you for the links, but after reading them I'm even more confused now.

On one of the links, the first half of the page says to store them at 50% rated capacity (from a ThunderPower rep), while the next paragraph says that according to Vamming ( a manufacturer of Li-Po's ), they should be charged at 80% of rated capacity.

Yet another link recommends neither 50 or 80, but 40%.

Can you understand my confusion?

Thank you anyway for trying to help me, I appreciate it!

Chuck

In simple terms LiPolys should be stored at between 3.7 and 4.0 volts per cell. 3.85 is exactly in the middle of this range.

Cool is better than warm.

Hi Charles,

Thank you very much for the help. I'll make sure to set them all at the 3.85v per cell figure, then store them in a cool place down here in the basement.

Thanks again!

Chuck
