recommended lipo for MMM and NEU

[blueb8llz]

i have a neu energy 5k 25c hard case lipo that runs good on my 7xl/mmm.
quick question, if i was to use my 2 sets of 7 cell 3300 gp nimh batteries, how many amps would that be? i never know how you guys configure amps and such.
should i even risk it? will it blow out my mmm by any chance? i dont really care for the batteries. i reemember reading the mmm's instuction and it says it needs alot of power/juice to make the esc happy. so will those gp 7 cells provide enough juice?
