Any limit to the C rating on a lipo in the Rustler VXL? I just picked up a 2S 6000mah 65c-130c battery, is this compatable with the VXL's esc and motor?
yes it is compatible, velineon motor doesn´t need a lots of amps, so a 20, 25, 30c will be fine.
The more "c's" on a battery the more power you get delivered to the ESC. The more power delivered to the ESC the shorter your runtimes, but they will be more fast and powerful. 65C is almost like a 3s 20c lipo. That should be fun. There is no limit, just be careful and watch your motor temps, and keep them cool because they need to stay cooler to not break quickly. If they overheat, consider gearing down.
Thanks for the help. I'm running 31/76 right now, thats how I bought the car. Whats the stock gearing on Rustler VXL?
Just for the record: a C-rating without knowing the capacity of a battery says nothing.
Even a 5000mAh 20C 3S will give you much more to speed than a 6000mAh 65C 2S. The first battery should be able to deliver 1100W, which a VXL system only consumes in rare peaks using high gearing. Although the 2S can deliver almost 2900W, the VXL system will never use it.
If you want a VW Beetle go fast, you don't want the Porsche 911's gas tank, but it's motor :-)

Well it's bad, but if the esc didn't melt I guess you're ok. You should look into buying a TRX brand fan for the esc. It'll drop right in and plugs into the esc.
My Black & Blue Rally is faster than your color...
Anyone tried the max amp 150c 3s lipo yet in a rusty.....

Are those con artists still in business?
Not really. The C rating of a 2S pack does not affect the voltage. If your 2S pack feels anything like your 3S pack, your 3S pack is no good. Also, the higher C rating will not deliver any more power through the esc than the motor asks for.

I liken the "C" rating to a McDonalds Milkshake straw to a normal size straw. The higher the "C" rating, the bigger the straw.
Try drinking McDonalds milkshake with a regular straw.....not gonna happen so easy. = low "C" rating
im confused on what this means 60c~130c....i have a vxl slash 2wd, im looking for a strong 2s lipo that wont burn nothing up, and a strong 3s also that wont burn nothin up....?????
What I learned from the forums was that current, amps & c rating do not push big power. Current is drawn, never pushed. So your not feeding a BL system with big power, but if you have a big power system it will feed off the higher mah, higher c rating battery packs. So a 2 pole VXL system is only going to pull x number of amps. Pretty low stuff. But with a castle power house system - a 5000 mah 25c pack will make less power than the 5000 mah 50c pack because the higher rated pack can deliver more to the BL system. The BL system that taxes the battery more benefits from higher amped packs. The BL combo that needs '25c' doesn't instantly become more powerful with a 50C battery. But the BL combo that needs '50c' starves the 25C pack and runs to it's full potential with a '50c' pack. Buts it's not about c rating. It's the combo of mah and c rating with a splash of quality in the manufacturer. there's a math combo to figure it alll out but it doesn't mean too much in the real world. Bigger isn't necessarily better, but safer and more 'constant'
Current is not drawn. If there is no battery, nothing happens. Current starts to run when there is a way for electrons to move from the negative to the positive battery lead.
If a combo can consume less power than the battery can provide, a more powerful battery makes no difference. If the combo can consume more than the battery can provide, adding a more powerful battery will increase performance.
