Kokam vs. E-tec...your thoughts?
Just wondering if anyone has seen or may have a comparison of these to battery suppliers? Trying to figure out why i'd want one brand over the other. I'm guessing one has a higer/better rate of C than the other, but can't really find a good write up on them. Anyone? Thanks,

I have both types of packs, and the Kokam 2s 1500 mAh
8c pack is the winner as far as I'm concerned. with an 8C
discharge it flys all but two of my fixed wing aircraft except one
that uses sub-c cells. It flys my HB V2 longer tham 3
BirdSeed packs put togather.

Hi all
To make your decision more complicated, the new Kokam (2100mAH) support 10C discharge. Then we have Thunder Power also.

RE: Kokam vs. E-tec...your thoughts?
I've got both types but use the 2 cell ETec 1200 packs in my Aerohawk which gives me around 20 plus mins. I prefer them because they are lighter than the Kokam 1500 HC pack.
Has anyone tried the older Kokam 1020 cells? They are lighter still but don't have the grunt being rated at a max of around 5C to 6C.
I also tried a 2p2s ETec 1200 pack (giving 2400 at 7.4v) but I found the extra weight just a little too much. It flew OK but I normally hover around half throttle and with the 2p2s 1200 pack it needed 2/3 to ¾ throttle.

I have a mini DF and just got a 2cell etec 1200.
It's pretty much a stock bird, and will fly for about 15 minutes until slightly sluggish with tail control. I do not want to run the lipo down anyway, and my motor gets pretty hot.
This setup works WELL for me. I'm afraid to fry my FETs if I use the 3 cells :-). Others have tried and succeeded, while others have failed.
Perhaps I will get a kokam 2 cell 1500 pack later on...I've heard great news about them as well.
