    Why go for higher voltage battery?

    I'm just coming back to RC! I understand that a higher mah battery helps with length of fun time but why the increase of voltage? Is it just to make the car faster or does it help else where? Thanks

    Its all about available current. mAh rating, C rating and voltage all play a part in available power/watts.

    Eaxmple
    5000mAh battery rated 25C
    5000mAh=5amps
    5Ax25C=125A

    2s @ 7.4V nominal=7.4x125A=925 watts
    3S @ 11.1V nominal=11.1x125A=1387.5 watts and so on.

    Slash 4x4 will draw 1200 watts if you have the right stuff to do it.

    It has a lot more power delivered to the ESC, it doesn't really have anything to do with runtime, just a ton more power. I run 2s, it goes plenty fast and it's awesome, but if you do decide to go 3s, you can expect the parts to start breaking more and more, and it will end up costing more in the end. It does make it fun to run though. Keep an eye out on motor and esc temps. If you get 3s, I would put fans on ESC and motor. 4s is not possible with the stock ESC and motor. 6s with a mamba monster would be crazy, and it would be stupid fast. Wheelies for days, no wait, wheelies until your bumper has disappeared on the road by friction. haha

    6s will fry your system

    If u want 6s you need a motor and esc capable of that power input

    Yes anything over 3s=magic smoke gets out. Even 3s will let the magic smoke out if you dont gear it correctly and keep a contant check on temps.

    More voltage = more motor rpm = more speed ( or torque if geared up)
