Lipo?
 

If a truck is set up for Lipo can it only run lipo?

What ESC?

cc mamba 25

That ESC can be programmed to run both NiMH (or NiCad) and Lipo. "thumbsup"

What about the novac rooster

the rooster crawler can run nimh or lipo up to 2s, although i run mine on 3s with an external cut off. no problems so far

come to think of it. if you set the esc for lipo i guess it will cut off nimh at the low voltage for lipo. that might reduce run time.

Does anything have to be done to the esc (rooster crawler) to switch between lipo and nimh?

yes .

1: hold the button down until both LED's come on

2:release button as soon as the LED's come on.

3 the 2 LED's will flash to show current throttle profile (1 flash for standard profile (nimh batteries). 2 flashes for lipo cut off on)(the rooster is only designed for 2s lipo)

4: quick press and release set button to change selection

5: the setting is stored in memory if button is not pressed within 3 seconds
