30C Continuous(ish) Lipo Discharge

if the testing equipment he is using is right...then sweet. proves a point....


as for the last paragraph...hes saying bashers pull 3c?
thats like saying " you bought a 500hp car, but its about the about 200 your typically gonna use" and dropping a 250hp motor in it instead

I think that he means that us bashers are harder on our batts. than racers. That's what I took out of it any way.

I think he's referring to the average amp draw that we pull. Bashers and Racers alike.

If you've ever really looked at an Eagletree graph, they turn out to be alot of spikes.

Average amp draw is surprizingly low. Although, Amp Spikes for 1/8 scale can easily hit 150 amps.

These spikes only last for maybe 1/4th of a second.

Yes....your 500hp motor that you operate at 40% of its capacity is going to last much longer, and should be more efficient than a 250hp motor operated at 90-100% of capacity.

IMO, this video means nothing without stating the brand name, lol, simply calling it a 'name brand' pack doesn't tell us anything.

As for efficiency, can't really say that, depends on displacement, forced induction or not, whether it's a high speed/low torque, or low speed/high torque, anywhere in between, etc.

Why is that?

True - shouldn't have thrown that in there.

[zeropointbug]

Don't you think it matters what brand it is? Is it just me?

[jhautz]

I think the point of this whole thing is that the "C" rating is total BS and im sure it is on all prands of lipo. If you did this same test on 10 different brands of lipo you would probably get the same results. Some would take 3 seconds to drop below 3v/cell and some of the better ones might take 2 or 3 times that long, but none would likely stand for a true constant discharge at the C rateing printed on the sticker.

Its all marketing BS.

[zeropointbug]

Maybe so, but I still think it means nothing when they don't state what brand they are using. I could go get a crap brand LiFePO4 cell and test it to the rated C rating and get much lower volts than the manufacturer would provide, does that mean A123's are crap?
