I have a pair of matching 6 cell 7.2v nimhs that I like to use along with my Lipos. Currently the nimhs sit unused most of the time (they're 5000mah, fairly new condition and I used them for my boats) my questions are:

Will they be severely damaged if I run them in series thru the Mamba Monster system or will they be ok if I go easy on the throttle?

Will the ESC auto detect the Nimh because I didn't see it in the Driver's Ed guide, can I just plug them in and run, will it damage the ESC etc...?
