Li Po Batteries and the Cold
I remember reading about LiPos and the cold weather not mixing too well, but I can't recall where I seen it. Do I have anything to be concerned about? I want to fly tomorrow and it'll be about 45 degrees out.

RE: Li Po Batteries and the Cold
I went out the other day when it was about that temp and my Li-polys would not produce the power, they were left outside the night before. I placed them on my dash and ran the defroster for a while and they all came back good as new.

Well, that's funny. I've never had a problem with the battery in my cell phone, my PDA or my laptop that was related to the temperature, and they all use Lipo or Li-ion batteries.

Dorasl, They would work, but would only produce about half power until warmed up. Maybe our phones, pda's, etc. don't draw enough, or the Li-ion's slightly different construction over the Li-polymer.
I too was always under the impression that you had to get down in the 30's to cause this problem. |
RE: Li Po Batteries and the Cold
Usually, all I need is a couple of circuits to build up the internal heat in my packs. I was flying a few weeks ago and it was 19 degrees. My larger planes would bearly get off the ground. I just ran them up on the ground for a minute, and all was fine. I do restrict the air inlets a little when it's really cold. Be careful doing this, though, as you need enough air to cool the ESC. Ask me how I know....LOLOL....40 degrees is borderline.....over that should be no problem...Under that you will see a drop off that is proportional to the temps, until the packs warm up.....Pat

I find that putting a couple of LI-PO`s in your coat pockets at the field prior to flying does the trick.....just takes the cold edge off them. I`m told Li-Po`s can be stored in the fridge if discharged properly for storage....not tried that though. |
