Having some power issues..

[rollincoal3500]

Ok so i got a brxl esc, castle 10amp, 7955 servo, 7 turn puller and a 2500 mah 40c 11.1 battery. My problem is that the wheel speed seems to go down with the battery.(like a nimh) The cells on both my batteries are all in good shape. With a freshly charged battery the wheel speed and torque are way higher then say about ten minutes in. Any help would be great... thanks

Does the motor or ESC get hot when it slows down? If so, maybe something in the drivetrain is binding?

How much charge does the battery take back in?
Is the LVC set in the ESC? If so, what is it set to?

Your pack description sounds good, so I doubt that is it. Does the same thing happen on any pack you run?

Well a freshly charged 3S lipo peaks at 12.6 volts but tapers down to the mid 11's for most of its charge before it then peters out and hits cut off.

Both the esc and motor dont get hot. Drivetrain is and rollin smooth. It does it on any 3 packs i run it on. Yes the lvc is set to 3.1 per cell.

That might have something to do with it. But it feels like it drops to running a 7.4 lipo batteries wheelspeed. Is there not enough mah? Is the puller motor drawing it to quick?

OK on the first part.

As to the packs, the 2400mah along with the 40C should be fine.

What pack connectors are you running? Hopefully not Tamiya's! Do the pack connectors get warm when the wheelspeed drops off?

Im running deans connectors. I havent check the conection for getting warm. Ill run it and see if it does.

i run a 7t puller on of my axials and that thing will kill a small pack rather quickly, when i first got it i tried some 2/3a 1500 packs i had, and it would barely move the rig for about 6-7 min and then the performance would drop, i now ran 2200mah 30c packs and feel the power drop after 15 min.

what kind of TX?
I was having a similar issue with my BRXL and found that the epa were low on my tx when I was calibrating the esc and tx.

Im running the spectrum dx3e. Ill try that and see it makes a difference thanks.
