I have been looking at the Traxxas LiPo batteries and see that the specs show a C rating of 25. Looking around I see that the C rating represents the current draw as a ratio to the capacity of the battery pack.
Can someone tell me how long and at what voltage these packs can maintain that C rating?
For instance, a 11.1 v 5000mAh pack with a C rating of 25 should produce 5A*25 or 125Amps. If I were to put a constant .088 ohm load on one of these packs, how long could I expect this pack to maintain 11.1 volts?
What would be a more typical extended load? I'm guessing very short bursts of less than 50 Amps with more regular bursts in the 30 Amp range with WOT on a flat surface being around 10Amps.
I am comparing these numbers to the typical laptop LiIon cell which is rated at 2200Ah and .4C. I can put a 4amp load on these for 30minutes but 30 Amps won't last more than a few seconds before the voltage drops to 2V.
I started off looking to build an electric go cart built from used laptop batteries and treadmill motors and came across Traxxas in my research. Now my son and I must own a couple of rustlers. Don't think we can swing the VXLs but I'm trying to scrape up the money for a couple of the XL5s.
