Ok yall , after a few battery swells over the past year, I have came to a conclusion that might be causeing battery failure,
Since I live in Alaska and deal with cold 10 1/2 months out of the year , (thats temps 55 degrees and lower) I have about 6 months to fly outside.
so I have had a fair share of swells and as everyone knows , it takes a while to send the packs out for repair or replace, and it can cause MADNESS, grief, and despare,
Im thinking that around 55 to 60 degrees tops and down that a embalance acures due to the outer cells getting cooled while discharging , while the inner cells are gaining in temps , as everyone knows , at 130 degrees the batteries come to life and discharge the best , well if its about 55 degrees outside temps , the outer cells never reach there discharge temps while the inner cells do , I have had 2 packs swell for no reason and a friend of mine at work had a battery go south , all the times the temps were below 60 degrees ,
so I would like to gather some info on other battery failures , how cold was it when you flew ?

I will incase my batteries this spring either with some sort of box , or maybe so sort of insulation to keep them warm ,

thanks ,
Tony

Tony,

I have had two go down on the mid 50's. One go down in the mid 80's, and one go down in the mid 90's.

They definitely perform better when it is hotter.
