I'm confused.......
But your following post ignored this point.
Oh dear !! You missed the word : unlikely
Again, this is contrary to what we (the membership) have learned through experience and reading posts over the past year. What we've learned is that battery temps below 20C enhance danger due to the risk of voltage lag, and battery temps below 15 C is outright dangerous and may lead to shut down without warning. And we've seen examples of this happening in real flying situations repeatedly. But apparently, we're all wrong.
WOW - what a crock of rubbish !! If what you say about 20C .... 15C ... was true - then temperate climate flyers would be failing !!
The world of RC flying is enjoyed in cold winters of Russia, Sweden, Canada and many other extremes .... suggest instead of just 'gut-replying' - a little consideration of actual is made.
Again, I am asking you to provide evidence - links, attachments, experience, something, anything - to support your statements and enlighten us all to these new findings.
Why not go to my Youtube site and watch my Winter flying .... some of it in temps as low as -10C ... -15C ....
Example battery tech sites :
Basic to Advanced Battery Information from Battery University
LIPO Battery Cold Weather Usage Tips
Does cold weather affect Lipos? - RC Groups
Lipo's and REALLY COLD Weather - RC Groups
Doesn't take much to find supporting evidence for my posts.
Are you aware of the general recc'd practice of storing LiPo's in the refrigerator ?
What temp do you maintain your house rooms at ? Do you charge / store your LiPo's in house or the garage / store / hobby room ? What temp is in there ?
Do you not agree that storing LiPo's fully charged is detrimental to their health ? It is recc'd to store at about 20 - 30% charge ?
Seems that we will not agree on various topics, fine - we are all entitled to our opinions. Trouble is with this one - it is not me flying in the face of facts.
I would suggest that anyone having a lipo fail in weather of 15C as you claim ... has assumed the temp. to be the cause instead of checking out fully. The problem I believe is that the Phantom being such an easy model to fly, literally any idiot can charge up and fly it. This leads to comments and bad information that gets supported by others similarly lacking in real technical information. The repeating and exapnding of such leads to it being accepted as gospel.
It means that when real info is given - its said to be wrong, to be contrary to the mass of postings before.
Years ago - the masses said the world was flat. A few said no - its round.
It would be interesting to know the iR of the offending battery for example .... The charge level at which it failed .... what was rested voltage after it failed ..... a lot of questions - but of course no answers because it is reported as failed and nothing else ....
I not only fly the Phantom - but all manner of LiPo and fuel powered models. I contribute to many forums and I have never read such claims as you have just made. I can just imagine the replies if such was posted on other forums I know....
My worry in such as this - is the misinformation that new flyers get and suffer consequences. We have a duty as 'experienced' to keep information as accurate as possible - to help newcomers .... Sorry but your claim is rejected as it is too vague in its detail. It lacks the answers as I have indicated.
I have gained useful information from many threads on this forum. But also noted some terrible errors.
