Does more Voltage give you more torque, or just more top end?

[Janders]

I've been debating upping the voltage(from 7.2 to 9.6 or more) on my twin/parallel motors to get more torque. I have more than enough top end, and can't gear any shorter. I'm still lacking on low end torque(for rockcrawling). Will voltage increase my low end 'grunt'?

unfortunetly no. upping ur voltage is the exact oppisite u want. it ups ur speed. upping ur current however will boost up ur torque.
the only other option i can see is just getting motors with more windings in them.

voltage = speed
current = torque

careful of upping ur current, because ur motor will get hotter also.
hoped this helped.

Ohm's Law dude...

Increasing the voltage WILL increase current demands. If your batteries can supply it, you will see an increase in torque AND speed.

[bomb-proof]

correct.....torque and speed will increase.

I just finished reading an electrical theory I got at radio shack. It seems that I may have to subject my superrooster to a few more cells, and due to the increased draw ->a second batt pack. This may give me an excuse to make a custom chassis...justneed to find some aluminum and some tools now..

As voltage increases, current increases... or, more volatge = good, until things start smoking:D

Also you can increase the current by decreaseing the resistance.

Motor, connectors, wire, ESP, but particularly the battery resistanse can be lowered.

Unfortunetly, I don't have any info on what batteries have low resistanse for reasonable prices.

I'm still being lazy and haven't switched to Dean's. I may see what 2 bat packs(reduce load/resistance). My batteries run hot now, while the ESC runs pretty cool, so I think my batts are definitely the weak point.
