I need a reason to upgrade? Or just something new.... I have shoerted it 2 times, and have over discharged it (5.6V) and she is still kickingYou keep putting down enerland cells, and you say on graphs the kokam is so much better, i want to see graphs, I cant find the TrakPower graphs after RCM's server crashed and they lost data, so I cant back up what I saw, there graphs on TrakPower's site, but there conditions, and real conditions are alot different... I AM looking, I know someone has it, I just have to get the right person

An Enerland cell used in the flightpower pack
http://www.slowflyer.ch/downloads/tn060051.pdf
vs a Kokam Cell in a Kokam pack
http://www.slowflyer.ch/downloads/tn07004.pdf
The Enerland cell lost 7% capacity in 36 cycles. After such a large loss in capacity - they elected to raise the voltage cutoff. Something they didn't do for any other cell.
The Kokam cell lost 8% capacity in 360 cycles.

the DC discharge graph on page 3 of the kokam one is interesting. below 20c those cells do some strange stuff!

Here are some graphs done by an independent source.

Thank you for backing that up!
Well, I cant say I still dont like my enerland stuff better, but that is impressive!

Sure you noticed
"With the initial setting for Vcutoff (2.9V/cell) 96% of the rated capacity was discharged but this was too
severe. The useful capacity decreased almost 7% during the first 36 cycles. With Vcutoff = 3.1V/cell there was
almost no degradation observed for the next 50 cycles."
With the Kokam pack 3,0v cutoff was used al the time. And surely you do not want to say if a lipo is better then the other because of that cutoff voltage.
Let's be careful with the comparisons.

My B44 is just about ready sooooo....I guess I'm ready for that kick in the nuts now.
If of course, you grow a pair and show up for the race!

Linger Kokam does not need that, and surely Enerland does not deserve that too.

I'll make it up to you though. I'll post some more comparison testing.
