I am trying to get a lipo for my m11, i have seen ppl using the 2S 7.4v or 3S 11.1V lipo, my question is.... would it be too much of Voltage if using 11.1v or would be it not enough of voltage if using the 7.4v, cuz currently i have been using 8 cells of 1.2v dry cell. My other question is if i chose to use 11.1v, do I care about the discharge rate like 10C or 15C or 20C? please advise. Thanks.
