Default Question about "Punch"

Okay, hopefully I can explain what I mean without sounding like a complete fool . Let's say a motor draws 10 amps (round numbers)...Battery A can pump out 30 amps....Battery B can put out 15 amps. Will Battery B be less "punchy" than battery A? Does this make sense to anyone? I hope you understand what I am getting at

Thanks!

Punch comes from volts available to the motor not the amps. I dont think todays packs are lacking available amperage even for hot mod motors. More volts=more rip.

In order to sort your battereis you need to know what there average dischage voltage is and how long there run time is.

ITs all about high average discharge voltage. You will get more punch with higher voltage batteries. The amp draw will come from the motor,gearing,traction and voltage output of a battery.

If you do not have a charger that can cycle your batteries you can normally find a guy at your local track or shop that can cycle your packs for you. You will get the average volts and run times as well as internal resistance ect ect..

Don't forget about low internal resistance...The lower,the more punch also!As the amps can flow to the motor faster!!

Thats right, you need equally as low IR's to let the voltage flow to the motor. Its kind of like water flow, if you have the same pressure but two different openings, the larger opening will let the water flow faster...but in this case the lower IR will let the voltage of the battery flow to the motor
