Eagletree results: Aftershock + 6S Zippy + 2200kv Castle
I may be hitting the battery a bit hard. :lol:

What pack specifically?
|
It's the 6S Zippy H 5000MAh pack. 20C-30C
|
So they hit 3.2v/cell at 38c burst? Not bad really, did you pull a temp from the pack at any time?
|
No, just used the hand-o-meter. It was barely warm. The motor temped at 117, and the pack wasn't near that, I'd say maybe 100 - 105?
|
.1 second sample rate?
|
Yep. The only way to fly. :) I can give you an excel data dump if you want, just will have to be tonight.

Great test....would love to see the higher 5000 MAH batts. They are wonderful batteries.... |
Just a bit of an amendment to what I said before. I've got the Zippy H 6S 5000MAh pack.
So I wasn't pulling 38C, it was more like 30.8C, which makes me feel a lot better, and also explains much better why the battery was that cool under that kind of load. At any rate, it's a stupid fast setup with boatloads of power that runs cool. What more could a person want? :) |

I'm asking this because I'm also converting a LST, (Actually same as Aftershock) the only thing I need are the batteries. I also have a MMM 2200kv combo, and will run it on 6S. |
I believe that I'm geared 24/66 and the speed is in the 40mph+ range. Plenty fast for my use. I was launching it into outer space with 5S; I can't even imagine how high/far I'd get with the current setup. :)

Nah, your not hitting the pack hard. You're only using 9 amps on average. I average about 18 amps with my 2650 motor in my 8ight and I am easy on the throttle. Wait until you gear high enough until it takes 50 amps just to maintain a constant speed. Then you are really testing your pack!
|
That 9A on average is misleading, because there's a fair bit of dead time in the graph that you don't see...it's averaging your draws over your total runtime. I don't pay attention to it. I look to see where the middle is between the peak and the bottom, that's a more useful average draw. This setup looks to take around 50A - 60A to maintain a constant speed, I just need a large enough space to test it!
