same 4 lipos stested at 14 amp draw

[Tele]

now its starts to get interesting..here are the results .. its interesting to see which batteries are able to keep the constant current draw and which other ones dropped off ..... the surprise one of the lot was the E tec for me
I was also impressed with the Jk volt one too

Wow hot staff, all above 70 degree, but both Etec and polyquest have a more stable discharge curve (power distribution) over the entire run time. The performance diff between the Etec 1700 and polyquest 1800 may not be significant enough to off set the extra weight vs capacity.

Thanks for the useful information

yah true but dont forget the cost factor ..I think the poly quest will be around the $100 mark I am just estimating. But yes very interesting results.

Does amp = watts???


Sorry, my electrical calculations has already been flushed away from my brain!!!


P=I*V or P=I/V ????



Need help.

W = Watt
V = Volt
I = Ampere or Current
R = Resistance

V = IR
W = VI

Since V = IR, therefore, W also equal to W = I^2R (I power of 2)

Since I = V/R. W also equal to W = (V^2) / R

This mean more business for Mack.... maybe more discounts or kopi treats for us as well?

The Etec maintains its voltage better for about 70% of the time. I would say the etec is a better pack for chopper. The Polyquest would be better for slo stick type aircraft.

With the price and service Etec would be the better choice.
