hi all...thanks for you time and advice worth its weight in gold.
so i am right just saying it wrong

what i ment was it would be better for the packs to be sharing the draw from the mmm combo rather than risk using them individualy (because they are only 20c there is a chance lipo could be damaged with the current draw of the mmm combo).
so i will have approx 200 amps on draw with 2 rather than approx 100 amps with one pack. or would i be better off just paying more for 1 30c pack.
like the idea of the 10,000mah tho run time would be sweet
