You want your motor burst rate to be less than your battery continuous rate

180 amp burst motor

5000mah 40c (200 amp cont) rate pack

That motor was overgeared in that graph, very high amps for a SC truck on 2s

Cheers

Ok, thanks for the info. I am planning on running my car these day and see what number I get. I should mount my GoPro camera to the car, facing the wattmeter, ha ha. That way I could see afterward what the actual amp draw was while driving.

Sorry, the novak has a 9 volt limit, I read you are running 4 cell. 14.8 v.

The wattsup meter will handle 60 volts, 50 amps continuous, 100 amp burst.

The nicest thing about the wattsup meter is it retains the highest amp draw during the run.
(That would be the peak amp reading)

To get this reading it goes between the battery & esc. After running the truck only unplug the meter from the esc. It will scroll thru all the peak readings.

CAUTION. Don't exceed 130 amps. (It could ruin your meter)


This one does show up to 80 volts, I could not find info on the other one. They do have a ? addy though.

Eagletree website appears to be down at the moment

The have two versions 100 Amp @ 70v ($60) or 150 amp @ 70v ($75)

Sensors for added functions cost a few bucks

They have a GPS module that works well allthough not cheap

Cheers

Or maybe 6s...

The one I have can handle 130A...


The nicest thing about the wattsup meter is it retains the highest amp draw or peak amps.
See, that is where I get confused?! I am never sure how to to take a C rating of a battery. I always thought that if your battery is rated at 100amps continuous, you can have peaks way higher than that, since they do not last longer than a split second...

I guess I have to find out more about what batteries a able to handle when it comes to amp draw... I always thought that the peak amps dont really matter since it is for such a short amount of time?!

thanks,
G

(I edited the post you quoted with corrections after posting this)

My lack of typing skills, Opps

The 100 amps I mentioned was for the watt meter not the battery. In your case don't exceed 130 amps or you could ruin your meter.

Yes for example a 100c/150(b or burst) is 100 constant amps & short bursts up to 150 amps.
The problem with burst's is they will build heat in the battery. That can possibly affect the battery in several ways
